Compared to the traditional single-process mode, it has the following characteristics: -- **Automatic Parallel Optimization**: Automatically optimize the application for parallelism at runtime without additional optimization costs; -- **Centralized Application Writing**: Easily orchestrate distributed application flow without distributed background knowledge; -- **Zero-Cost Automatic Migration**: Centralized Multi-Agent applications can be easily converted to distributed mode +- **High Performance**: Different agents and other services within the same application can run on different processes or even different machines, fully utilizing computing resources to unleash performance. +- **Automatic Parallelization**: Based on the Actor model, each agent has an independent state. When implementing applications, there's no need to consider invocation order, resource competition, etc., enabling automatic application parallelization. +- **Zero Migration Cost**: The code is fully compatible with the single-machine mode. Applications that can run in single-process mode can be migrated to the distributed mode at zero cost. -This tutorial will introduce the implementation and usage of AgentScope distributed in detail. +This section will detail the usage of AgentScope's distributed mode and introduce its principles. -## Usage +(basic_usage-en)= -In AgentScope, the process that runs the application flow is called the **main process**, and each agent can run in a separate process named **agent server process**. -According to the different relationships between the main process and the agent server process, AgentScope supports two modes for each agent: **Child Process** and **Independent Process** mode. +## Basic Usage -- In the Child Process Mode, agent server processes will be automatically started as sub-processes from the main process. -- While in the Independent Process Mode, the agent server process is independent of the main process and developers need to start the agent server process on the corresponding machine. +The distributed mode requires almost no modification to the running code compared to the traditional mode. Simply call the {func}`to_dist` function during the agent initialization phase. -The above concepts may seem complex, but don't worry, for application developers, you only need to convert your existing agent to its distributed version. +```python +# import some packages -### Step 1: Convert your agent to its distributed version +# init agentscope -All agents in AgentScope can automatically convert to its distributed version by calling its {func}`to_dist` method. -But note that your agent must inherit from the {class}`agentscope.agents.AgentBase` class, because the `to_dist` method is provided by the `AgentBase` class. +# Initialization in traditional mode +# agent = Agent(...) -Suppose there are two agent classes `AgentA` and `AgentB`, both of which inherit from `AgentBase`. +# Initialization in distributed mode +agent = Agent(...).to_dist() -```python -a = AgentA( - name="A" - # ... -) -b = AgentB( - name="B" - # ... -) +x = Msg(...) +y = agent(x) ``` -Next we will introduce the conversion details of both modes. - -#### Child Process Mode +In this section, we will demonstrate how to specifically use AgentScope's distributed mode with a webpage retrieval example. To highlight the acceleration effect brought by AgentScope's distributed mode, a simple custom `WebAgent` is used here. +This agent simulates the process of crawling webpages and looking for answers by sleeping for 5 seconds. In the example, there are a total of 5 agents, each crawling a webpage and searching for answers. -To use this mode, you only need to call each agent's `to_dist()` method without any input parameter. AgentScope will automatically start all agent server processes from the main process. +The only difference between the traditional mode and the distributed mode lies in the initialization phase, specifically in `init_without_dist` and `init_with_dist`. +The only difference in `init_with_dist` compared to `init_without_dist` is the additional call to the `to_dist` function. +After initialization, the `run` function is exactly the same for both modes. However, the running time differs significantly between the two modes. ```python -# Child Process mode -a = AgentA( - name="A" - # ... -).to_dist() -b = AgentB( - name="B" - # ... -).to_dist() +# Please do not run this code in a Jupyter notebook +# Copy the code to a `dist_main.py` file and run it using `python dist_main.py` +# Ensure you have installed the distributed version of agentscope before running the code +# pip install agentscope[distribute] + +import time +import agentscope +from agentscope.agents import AgentBase +from agentscope.message import Msg + +class WebAgent(AgentBase): + + def __init__(self, name): + super().__init__(name) + + def get_answer(self, url: str, query: str): + """Simulate crawling the web and looking for answers""" + time.sleep(5) + return f"Answer from {self.name}" + + def reply(self, x: dict = None) -> dict: + return Msg( + name=self.name, + role="assistant", + content=self.get_answer(x.content["url"], x.content["query"]) + ) + + +QUERY = "example query" +URLS = ["page_1", "page_2", "page_3", "page_4", "page_5"] + +def init_without_dist(): + return [WebAgent(f"W{i}") for i in range(len(URLS))] + + +def init_with_dist(): + return [WebAgent(f"W{i}").to_dist() for i in range(len(URLS))] + + +def run(agents): + start = time.time() + results = [] + for i, url in enumerate(URLS): + results.append(agents[i].reply( + Msg( + name="system", + role="system", + content={ + "url": url, + "query": QUERY + } + ) + )) + for result in results: + print(result.content) + end = time.time() + return end - start + + +if __name__ == "__main__": + agentscope.init() + start = time.time() + simple_agents = init_without_dist() + dist_agents = init_with_dist() + end = time.time() + print(f"Time taken for initialization: {end - start}") + print(f"Time taken without distributed mode: {run(simple_agents)}") + print(f"Time taken with distributed mode: {run(dist_agents)}") ``` -#### Independent Process Mode +Sample output of the above code is as follows: + +```text +Time taken for initialization: 12.944042921066284 +[W0] Answer from page_1 +[W1] Answer from page_2 +[W2] Answer from page_3 +[W3] Answer from page_4 +[W4] Answer from page_5 +Time taken without distributed mode: 25.022241830825806 +[W0] Answer from page_1 +[W1] Answer from page_2 +[W2] Answer from page_3 +[W3] Answer from page_4 +[W4] Answer from page_5 +Time taken with distributed mode: 5.021369934082031 +``` -In the Independent Process Mode, we need to start the agent server process on the target machine first. -When starting the agent server process, you need to specify a model config file, which contains the models which can be used in the agent server, the IP address and port of the agent server process -For example, start two agent server processes on the two different machines with IP `ip_a` and `ip_b`(called `Machine1` and `Machine2` accrodingly). -You can run the following code on `Machine1`.Before running, make sure that the machine has access to all models that used in your application, specifically, you need to put your model config file in `model_config_path_a` and set environment variables such as your model API key correctly in `Machine1`. The example model config file instances are located under `examples/model_configs_template`. In addition, your customized agent classes that need to run in the server must be registered in `custom_agent_classes` so that the server can correctly identify these agents. If you only use AgentScope's built-in agents, you can ignore `custom_agent_classes` field. +As observed from the output, there is a significant reduction in running time when using the distributed mode (from 25 seconds to 5 seconds). +The example above represents the most common usage of AgentScope's distributed mode. When not aiming for ultimate performance or the number of Agents is relatively small (e.g., no more than 10), it is advisable to use the method demonstrated above. +For further performance optimization, a deeper understanding of AgentScope's distributed model is required, and subsequent sections will introduce advanced usage of the distributed mode in detail. -```python -# import some packages +## Advanced Usage -# register models which can be used in the server -agentscope.init( - model_configs=model_config_path_a, -) -# Create an agent service process -server = RpcAgentServerLauncher( - host="ip_a", - port=12001, # choose an available port - custom_agent_classes=[AgentA, AgentB] # register your customized agent classes -) +This section will introduce advanced uses of the AgentScope distributed mode to further enhance efficiency. Before delving into advanced usage, we need to have a basic understanding of the fundamental concepts of the AgentScope distributed mode. -# Start the service -server.launch() -server.wait_until_terminate() -``` +### Fundamental Concepts -For simplicity, you can run the following command in your terminal rather than the above code: +- **Main Process**: The process where the AgentScope application resides is called the main process. For instance, the `run` function in the example from the previous section runs in the main process. Each AgentScope application will have only one main process. +- **Agent Server Process**: In distributed mode, the agent server process is where agents run. For example, in the example from the previous section, all agents in `dist_agents` actually run in the agent server process. Multiple agent server processes can exist at the same time. Agent server processes can run on any network-accessible node, and within each agent server process, multiple agents can run simultaneously. -```shell -as_server --host ip_a --port 12001 --model-config-path model_config_path_a --agent-dir parent_dir_of_agent_a_and_b -``` +- **Child Mode**: In child mode, the agent server process is spawned as a child process by the main process. In the example from the previous section, each agent in `dist_agents` is actually a child process of the main process. This mode is the default running mode for AgentScope distributed applications, meaning that when calling the `to_dist` function without any parameters, it defaults to this mode. This mode is employed in the [basic usage](#basic_usage-en) section. +- **Independent Mode**: In independent mode, the agent processes are independent of the main process. The agent processes need to be started on the machine in advance, and certain parameters need to be passed to the `to_dist` function. This mode must be used if agents need to be deployed across different machines. Additionally, this mode is recommended if performance is major concern, or you have a large number of agents. -> Note: -> The `--agent-dir` field is used to specify the directory where your customized agent classes are located. -> Please make sure that all custom Agent classes are located in `--agent-dir`, and that the custom modules they depend on are also located in the directory. -> Additionally, because the above command will load all Python files in the directory, please ensure that the directory does not contain any malicious files to avoid security risks. +### Using Independent Mode -Then put your model config file accordingly in `model_config_path_b`, set environment variables, and run the following code on `Machine2`. +Compared to child mode, independent mode can avoid the overhead of initializing child processes during runtime, thereby eliminating startup latency and enhancing operational efficiency in scenarios with many agents. -```python -# import some packages +In independent mode, agent server processes need to be started in advance on the machines, and the `host` and `port` of the agent server process to connect to should be passed to the `to_dist` function. -# register models which can be used in the server -agentscope.init( - model_configs=model_config_path_b, -) -# Create an agent service process -server = RpcAgentServerLauncher( - host="ip_b", - port=12002, # choose an available port - custom_agent_classes=[AgentA, AgentB] # register your customized agent classes -) +We will still use the example from the basic usage section for demonstration. Assuming the code file from the [basic usage](#basic_usage-en) section is named `dist_main.py`, the following code should be saved as `dist_server.py`. -# Start the service -server.launch() -server.wait_until_terminate() +```python +# Do not run this code in a Jupyter notebook +# Copy the code to a file named `dist_server.py` and run it using the command `python dist_server.py`. The directory structure should be: +# your_project_dir +# ├── dist_main.py +# └── dist_server.py +# Install the distributed version of agentscope before running the code +# pip install agentscope[distribute] + +import agentscope +from agentscope.server import RpcAgentServerLauncher +from dist_main import WebAgent + +if __name__ == "__main__": + agentscope.init( + # model_configs=... # Model configuration. If no model is needed, this parameter can be omitted. + ) + assistant_server_launcher = RpcAgentServerLauncher( + host="localhost", + port=12345, + custom_agent_classes=[WebAgent], + ) + assistant_server_launcher.launch(in_subprocess=False) + assistant_server_launcher.wait_until_terminate() ``` -> Similarly, you can run the following command in your terminal to setup the agent server: -> -> ```shell -> as_server --host ip_b --port 12002 --model-config-path model_config_path_b --agent-dir parent_dir_of_agent_a_and_b -> ``` +In the above code, we use `RpcAgentServerLauncher` to start an agent server process. Note that `WebAgent` is not an agent implementation provided by AgentScope, so it needs to be added to `custom_agent_classes`. Additionally, if model APIs are required in the agent server process, corresponding model parameters should be configured in `agentscope.init`. -Then, you can connect to the agent servers from the main process with the following code. +Furthermore, the `init_with_dist` function in `dist_main.py` needs to be updated to the following code: ```python -a = AgentA( - name="A", - # ... -).to_dist( - host="ip_a", - port=12001, -) -b = AgentB( - name="B", - # ... -).to_dist( - host="ip_b", - port=12002, -) +def init_with_dist(): + return [WebAgent(f"W{i}").to_dist(host="localhost", port=12345) for i in range(len(URLS))] ``` -The above code will deploy `AgentA` on the agent server process of `Machine1` and `AgentB` on the agent server process of `Machine2`. -And developers just need to write the application flow in a centralized way in the main process. +In this new version of `init_with_dist`, two new parameters, `host` and `port`, are added to connect to the agent server process. + +After modifying the code, run the `dist_server.py` file in one command line and wait for it to start successfully. Then run the `dist_main.py` file in another command line. During execution, the following output will be displayed: + +```text +Initialization time: 0.005397319793701172 +[W0] Answer from page_1 +[W1] Answer from page_2 +[W2] Answer from page_3 +[W3] Answer from page_4 +[W4] Answer from page_5 +Non-distributed mode runtime: 25.023009061813354 +[W0] Answer from page_1 +[W1] Answer from page_2 +[W2] Answer from page_3 +[W3] Answer from page_4 +[W4] Answer from page_5 +Distributed mode runtime: 5.021481990814209 +``` -### Step 2: Orchestrate Distributed Application Flow +At this point, the initialization time of `dist_main.py` will be significantly reduced, for instance, just 0.005 seconds in this case. -> Note: -> Currently, distributed version of Agent only supports `__call__` method call (i.e. `agent(x)`), not support calling other methods or reading/writing properties. +### Avoiding Repeated Initialization -In AgentScope, the orchestration of distributed application flow is exactly the same as non-distributed programs, and developers can write the entire application flow in a centralized way. -At the same time, AgentScope allows the use of a mixture of locally and distributed deployed agents, and developers do not need to distinguish which agents are local and which are distributed. +The above code calls the `to_dist` function on an already initialized agent. `to_dist` essentially clones the original agent to the agent server process, retaining an {class}`RpcObject` in the main process as a proxy for the original agent. Calls to this `RpcObject` are forwarded to the corresponding agent in the agent server process. -The following is the complete code for two agents to communicate with each other in different modes. It can be seen that AgentScope supports zero-cost migration of distributed application flow from centralized to distributed. +This process has a potential issue: the original agent is initialized twice, once in the main process and once in the agent server process. These two initializations occur sequentially, lacking the ability to be parallelized. For agents with low initialization costs, directly calling the `to_dist` function will not significantly impact performance. However, for agents with high initialization costs, repeated initialization should be avoided. Therefore, AgentScope distributed mode provides another method for initializing in distributed mode, which entails passing the `to_dist` parameter directly within the initialization function of any agent. The following code modifies the `init_with_dist` function in `dist_main.py`. -- All agents are centralized +- For child mode, simply pass `to_dist=True` in the initialization function. -```python -# Create agent objects -a = AgentA( - name="A", - # ... -) + ```python + def init_with_dist(): + return [WebAgent(f"W{i}", to_dist=True) for i in range(len(URLS))] + ``` -b = AgentB( - name="B", - # ... -) +- For independent mode, pass the parameters previously given to the `to_dist` function as a dictionary to the `to_dist` field. -# Application flow orchestration -x = None -while x is None or x.content == "exit": - x = a(x) - x = b(x) -``` + ```python + def init_with_dist(): + return [WebAgent(f"W{i}", to_dist={"host": "localhost", "port": "12345"}) for i in range(len(URLS))] + ``` -- Agents are deployed in a distributed manner - - `AgentA` in Child Process mode - - `AgentB` in Independent Process Mode +```{note} +Some IDEs might display a hint indicating that the `to_dist` parameter does not exist, but this will not cause an error at runtime. +Additionally, if the `to_dist` parameter has already been passed in the initialization parameters, the `to_dist` method should not be called again. +``` -```python -# Create agent objects -a = AgentA( - name="A" - # ... -).to_dist() - -b = AgentB( - name="B", - # ... -).to_dist( - host="ip_b", - port=12002, -) +## Developer Guide -# Application flow orchestration -x = None -while x is None or x.content == "exit": - x = a(x) - x = b(x) +```{note} +This section is aimed at developers who are developing new features based on the AgentScope distributed mode. It requires a certain understanding of distributed programming principles such as processes, threads, synchronization, asynchronicity, gRPC, Python metaclasses, and the Global Interpreter Lock (GIL). Even if you lack the aforementioned background, reading this section will still provide insights into the fundamental principles and advanced usages of the AgentScope distributed mode. ``` -### Advanced Usage +The core logic of the AgentScope distributed model is: -#### `to_dist` with lower cost +**By using the `to_dist` function or initialization parameters, objects that originally run in any Python process are transferred to an RPC server. In the original process, a `RpcObject` proxy is retained, and any function call or attribute access on this `RpcObject` will be forwarded to the object on the RPC server. When calling functions, you can decide whether to use synchronous or asynchronous invocation.** -All examples described above convert initialized agents into their distributed version through the {func}`to_dist` method, which is equivalent to initialize the agent twice, once in the main process and once in the agent server process. -For agents whose initialization process is time-consuming, the `to_dist` method is inefficient. Therefore, AgentScope also provides a method to convert the Agent instance into its distributed version while initializing it, that is, passing in `to_dist` parameter to the Agent's initialization function. +The following graph illustrate the workflow of `to_dist`, synchronous and asynchronous invocation. -In Child Process Mode, just pass `to_dist=True` to the Agent's initialization function. - -```python -# Child Process mode -a = AgentA( - name="A", - # ... - to_dist=True -) -b = AgentB( - name="B", - # ... - to_dist=True -) +```{mermaid} +sequenceDiagram + User -->> Process: initialize + Process -->> RPC Server: to_dist + User -->> Process: sync function call + Process -->> RPC Server: sync function call + RPC Server -->> RPC Server: calculate result + RPC Server -->> Process: sync result + Process -->> User: sync result + User -->> Process: async function call + Process -->> RPC Server: async function call + RPC Server -->> RPC Server: calculate result + User -->> Process: get async result + Process -->> RPC Server: get async result + RPC Server -->> Process: async result + Process -->> User: async result ``` -In Independent Process Mode, you need to encapsulate the parameters of the `to_dist()` method in {class}`DistConf` instance and pass it into the `to_dist` field, for example: +As illustrated in the previous figure, the distributed mode of AgentScope essentially follows a Client-Server architecture. In this setup, the user-authored agent applications (Processes) act as the Client, while the agent server process (RPC Server) functions as the Server. In distributed mode, the Client side sends the local agents to the Server side for execution. The Client forwards local function calls and property accesses to the Server, which is responsible for receiving the agents and handling various invocation requests from the Client. -```python -a = AgentA( - name="A", - # ... - to_dist=DistConf( - host="ip_a", - port=12001, - ), -) -b = AgentB( - name="B", - # ... - to_dist=DistConf( - host="ip_b", - port=12002, - ), -) +```{note} +Communication between the Client and Server in AgentScope's distributed mode is implemented using gRPC. There is a strict limitation on the size of messages send/recv; by default, a single message cannot exceed 32 MB. This value can be further increased by modifying the `_DEFAULT_RPC_OPTIONS` parameter in `src/agentscope/constants.py`. ``` -Compared with the original `to_dist()` function call, this method just initializes the agent once in the agent server process, which reduces the cost of initialization. +Next, we'll introduce the implementation of the Client and Server respectively. -#### Manage your agent server processes +### Client Side -When running large-scale multi-agent applications, it's common to have multiple Agent Server processes running. To facilitate management of these processes, AgentScope offers management interfaces in the {class}`RpcAgentClient` class. Here's a brief overview of these methods: +The Client Side mainly consists of two primary classes: `RpcMeta` and `RpcObject`. `RpcMeta` is responsible for sending local objects to the Server, while `RpcObject` handles the forwarding of subsequent invocation requests. -- `is_alive`: This method checks whether the Agent Server process is still running. +#### `RpcMeta` - ```python - client = RpcAgentClient(host=server_host, port=server_port) - if client.is_alive(): - do_something() - ``` +The class {class}`RpcMeta` is a metaclass that automatically adds the `to_dist` method and `to_dist` initialization parameter to its subclasses (thus IDEs might indicate `to_dist` parameter does not exist, but in actuality, it won't cause an error during runtime). Its implementation can be found in `src/agentscope/rpc/rpc_meta.py`. -- `stop`: This method stops the Agent Server process. +Calling the `to_dist` method on an already initialized object sends the object's initialization parameters to the Agent Server Process and reinitializes the object within that process. The main process returns a `RpcObject` to replace the original object. - ```python - client.stop() - assert(client.is_alive() == False) - ``` +Since the original object is reconstructed using initialization parameters, it cannot maintain state changes that occurred after creation. Thus, it is recommended to call the `to_dist` method immediately upon initialization or pass the `to_dist` parameter directly in the object's initialization function. -- `get_agent_list`: This method retrieves a list of JSON format thumbnails of all agents currently running within the Agent Server process. The thumbnail is generated by the `__str__` method of the Agent instance. +Since `to_dist` is automatically added to subclasses by `RpcMeta`, any class that inherits from `RpcMeta`, not just `Agent` classes, can use the `to_dist` method. - ```python - agent_list = client.get_agent_list() - print(agent_list) # [agent1_info, agent2_info, ...] - ``` +In addition to providing the `to_dist` method, `RpcMeta` also records callable methods and attributes from the original object to facilitate invocation within the `RpcObject`. By default, only public methods of the original object are recorded and invoked synchronously (the caller is blocked until the method on the original object has finished executing). If asynchronous invocation is needed, the `async_func` decorator should be added to the method declaration. -- `get_agent_memory`: With this method, you can fetch the memory content of an agent specified by its `agent_id`. +#### `async_func` and `AsyncResult` - ```python - agent_id = my_agent.agent_id - agent_memory = client.get_agent_memory(agent_id) - print(agent_memory) # [msg1, msg2, ...] - ``` +The decorator {func}`async_func` is implemented in `src/agentscope/rpc/rpc_meta.py`. The `__call__` and `reply` methods of `AgentBase` and all its subclasses are marked with `async_func` to avoid blocking. -- `get_server_info`：This method provides information about the resource utilization of the Agent Server process, including CPU usage, memory consumption. +In contrast to `async_func`, there is also the {func}`sync_func` decorator, used to indicate synchronous methods. However, since synchronous methods are the default, it is generally not used. - ```python - server_info = client.get_server_info() - print(server_info) # { "cpu": xxx, "mem": xxx } - ``` +Below is a simple example where we declare a class `Example`. In this class, `sync_method` is a synchronous method, `async_method_basic` and `async_method_complex` are marked as asynchronous methods, and `_protected_method` is a private method. -- `set_model_configs`: This method set the specific model configs into the agent server, the agent created later can directly use these model configs. +```python +import time +from agentscope.rpc import RpcMeta, async_func + +class Example(metaclass=RpcMeta): + + # @sync_func # Default is sync_func, can be omitted + def sync_method(self) -> str: + # Synchronous method, caller will be blocked for 1 s + time.sleep(1) + return "sync" + + @async_func + def async_method_basic(self) -> str: + # Asynchronous method, caller will not be blocked and can continue until attempting to get the result + time.sleep(1) + # Return a basic type + return "async" + + @async_func + def async_method_composite(self) -> dict: + # Asynchronous method + time.sleep(1) + # Return a dictionary + return {"a": 1, "b": 2, "c": "hello world"} + + def _protected_method(self) -> str: + # Not a public method, rpc object cannot call this method + time.sleep(1) + return "protected" + +if __name__ == "__main__": + example = Example(to_dist=True) + # Calling protected method will result in undefined behavior, avoid using it + # protected_result = example._protected_method() + t1 = time.time() + sync_result = example.sync_method() + assert sync_result == "sync" + t2 = time.time() + print(f"Sync func cost: {t2 - t1} s") + t3 = time.time() + async_basic = example.async_method_basic() + async_composite = example.async_method_composite() + t4 = time.time() + print(f"Async func cost: {t4 - t3} s") + # Basic type results need to call the result method to get the asynchronous execution result + assert async_basic.result() == "async" + # Composite types automatically update asynchronous execution results when accessing required fields + assert async_composite["a"] == 1 + assert async_composite["b"] == 2 + assert async_composite["c"] == "hello world" +``` - ```python - agent = MyAgent( # failed because the model config [my_openai] is not found - # ... - model_config_name="my_openai", - to_dist={ - # ... - } - ) - client.set_model_configs([{ # set the model config [my_openai] - "config_name": "my_openai", - "model_type": "openai_chat", - # ... - }]) - agent = MyAgent( # success - # ... - model_config_name="my_openai", - to_dist={ - # ... - } - ) - ``` +The result of running the above code sample is shown below. You can observe that the time taken to call `async_method` is much shorter than `sync_method`. This is because `async_method` is asynchronous and does not block the caller, whereas `sync_method` is synchronous and blocks the caller. -- `delete_agent`: This method deletes an agent specified by its `agent_id`. +```text +Sync func cost: 1.0073761940002441 s +Async func cost: 0.0003597736358642578 s +``` - ```python - agent_id = agent.agent_id - ok = client.delete_agent(agent_id) - ``` +In the above code, `async_method_basic` and `async_method_complex` return instances of the {class}`AsyncResult` class. This object can return the result of asynchronous execution through its `result` method. To maintain a consistent interface between asynchronous and synchronous calls, if the result represented by `AsyncResult` is a composite type, you do not need to call the `result` method manually. When accessing internal attributes, `result` is automatically called to update the execution result (as shown in the example for `async_composite`). -- `delete_all_agent`: This method deletes all agents currently running within the Agent Server process. +#### `RpcObject` - ```python - ok = client.delete_all_agent() - ``` +{class}`RpcObject` is implemented in `src/agentscope/rpc/rpc_object.py`. +`RpcObject` acts as a proxy and does not contain any attribute values or methods of the original object. It only records the address of the agent server process where the original object resides and the object's `id`. With these parameters, `RpcObject` can connect to the original object over the network, enabling invocation on the original object. -#### Connecting to AgentScope Studio +When a user calls methods or accesses attributes on a `RpcObject`, `RpcObject` will forward the request to the original object located in the agent server process through its `__getattr__` method. For synchronous method invocations (`@sync_func`) or attribute access, `RpcObject` will block the caller until the method on the original object completes execution and returns the result. In the case of asynchronous methods (`@async_func`), it immediately returns an {class}`AsyncResult` object. The main process can continue running without blocking if it doesn't access the specific value of this object. To obtain the execution result, the `result` method of the `AsyncResult` object needs to be called, which will block the caller if the result has not yet been returned. -The agent server process can be connected to [AgentScope Studio](#209-gui-en) at startup, allowing the `to_dist` method in subsequent distributed applications to be assigned automatically by Studio without the need for any parameters. +```{note} +When initializing `RpcObject`, if `host` and `port` parameters are not provided (i.e., sub-process mode), a new Agent Server process is started and the original object is recreated in that process. Starting a new Agent Server process is relatively slow, which is why initialization time is longer in sub-process mode. +If `host` and `port` parameters are provided (i.e., standalone process mode), `RpcObject` directly connects to the server and recreates the original object, avoiding the overhead of starting a new process. +``` -For scenarios where the agent server process is started using Python code, simply fill in the `studio_url` in the initialization parameters of `RpcAgentServerLauncher`. This requires that the URL is correct and accessible over the network, for example, the default URL for the Studio is `http://127.0.0.1:5000`. +### Server-Side -```python -# import some packages +The server side is primarily based on gRPC and mainly consists of the `AgentServerServicer` and `RpcAgentServerLauncher` classes. -# register models which can be used in the server -agentscope.init( - model_configs=model_config_path_a, -) -# Create an agent service process -server = RpcAgentServerLauncher( - host="ip_a", - port=12001, # choose an available port - custom_agent_classes=[...], # register your customized agent classes - studio_url="http://studio_ip:studio_port", # connect to AgentScope Studio -) +#### `AgentServerLauncher` -# Start the service -server.launch() -server.wait_until_terminate() -``` +The implementation of `AgentServerLauncher` is located at `src/agentscope/server/launcher.py`, and it is used to launch the gRPC Server process. Specifically, to ensure that the server process can correctly reinitialize the objects sent from the client side and correctly call the model API services, it is necessary to register all subclasses of `RpcMeta` that may be used during runtime when launching the server, and properly set the model configurations. There are two ways to launch the server: through python code or command-line instructions. -For scenarios using the command `as_server` in your command line, simply fill in the `--studio-url` parameter. +- The method to launch through python code is as follows. You need to specify `host` and `port`, as well as `custom_agent_classes`, and you also need to pass the required model configurations when calling `agentscope.init`. Suppose there are custom classes `AgentA`, `AgentB`, and `AgentC` that need to be registered, and all three classes are located in the `myagents.py` file and are subclasses of `AgentBase`. -```shell -as_server --host ip_a --port 12001 --model-config-path model_config_path_a --agent-dir parent_dir_of_agent_a_and_b --studio-url http://studio_ip:studio_port -``` + ```python + import agentscope + from agentscope.server import RpcAgentServerLauncher + from myagents import AgentA, AgentB, AgentC -After executing the above code or command, you can enter the Server Manager page of AgentScope Studio to check if the connection is successful. If the connection is successful, the agent server process will be displayed in the page table, and you can observe the running status and resource occupation of the process in the page, then you can use the advanced functions brought by AgentScope Studio. This section will focus on the impact of `to_dist` method brought by AgentScope Studio, and please refer to [AgentScope Studio](#209-gui-en) for the specific usage of the page. + MODEL_CONFIGS = {} -After the agent server process successfully connects to Studio, you only need to pass the `studio_url` of this Studio in the `agentscope.init` method, and then the `to_dist` method no longer needs to fill in the `host` and `port` fields, but automatically select an agent server process that has been connected to Studio. + HOST = "localhost" + PORT = 12345 + CUSTOM_CLASSES = [AgentA, AgentB, AgentC] -```python -# import some packages + if __name__ == "__main__": + agentscope.init( + model_configs=MODEL_CONFIGS, + ) + launcher = RpcAgentServerLauncher( + host=HOST, + port=PORT, + custom_agent_classes=CUSTOM_CLASSES, + ) + launcher.launch(in_subprocess=False) + launcher.wait_until_terminate() + ``` -agentscope.init( - model_configs=model_config_path_a, - studio_url="http://studio_ip:studio_port", -) +- The method to launch through command line is as follows. In addition to specifying `host` and `port`, you also need to specify `model_config_path` and `agent_dir`, which correspond to the model configuration file path and the directory where custom agent classes are located, respectively. When installing `agentscope`, the `as_server` command will be installed by default, so you can directly use this command in the command line. -a = AgentA( - name="A" - # ... -).to_dist() # automatically select an agent server + ```shell + as_server start --host localhost --port 12345 --model-config-path model_config_path --agent-dir parent_dir_of_myagents.py + ``` -# your application code +```{warning} +`AgentServerLauncher` will load and execute custom Python objects. Please thoroughly inspect the objects being loaded before use, as they might contain malicious code that could cause severe system damage. The `AgentServerLauncher` class also has a `local_mode` parameter indicating whether only local access is allowed. It defaults to `True`. If access from other machines is required, it should be set to `False`. To avoid network attacks, please only use it in a trusted network environment. ``` -> Note: -> -> - The Agent used in this method must be registered at the start of the agent server process through `custom_agent_classes` or `--agent-dir`. -> - When using this method, make sure that the agent server process connected to Studio is still running normally. +#### `AgentServerServicer` -After the application starts running, you can observe in the Server Manager page of Studio which agent server process this Agent is specifically running on, and after the application is completed, you can also delete this Agent through the Server Manager page. +The implementation of `AgentServerServicer` is located at `src/agentscope/server/servicer.py`. It is the implementation of the gRPC service responsible for receiving and processing various requests sent from the client side. -## Implementation +The `create_agent` method is called when the client uses `to_dist` on an object of a subclass of `RpcMeta`. It recreates the original object on the server and stores it in the `agent_pool` field with `id` as the key. -### Actor Model +The `call_agent_func` method is called when the client calls methods or properties on `RpcObject` objects. The input parameters include the `id` of the object being called and the name of the method being called. The specific calling process varies slightly. For synchronous methods and property access, `call_agent_func` retrieves the object from `agent_pool`, calls the corresponding method or property, and blocks the caller until it returns the result. For asynchronous methods, `call_agent_func` packages the input parameters and places them in a task queue, immediately returning the task's `task_id` to avoid blocking the caller. -[The Actor model](https://en.wikipedia.org/wiki/Actor_model) is a widely used programming paradigm in large-scale distributed systems, and it is also applied in the distributed design of the AgentScope platform. +The `AgentServerServicer` has an executor pool to automatically execute tasks (`_process_task`). The results of these tasks are then placed into a `result_pool`. The `result` method of `AsyncResult` attempts to fetch the corresponding task result from the `result_pool`. If the task result does not exist, it will block the caller until the result is available. -In the distributed mode of AgentScope, each Agent is an Actor and interacts with other Agents through messages. The flow of messages implies the execution order of the Agents. Each Agent has a `reply` method, which consumes a message and generates another message, and the generated message can be sent to other Agents. For example, the following chart shows the workflow of multiple Agents. `A`~`F` are all Agents, and the arrows represent messages. +##### `executor` -```{mermaid} -graph LR; -A-->B -A-->C -B-->D -C-->D -E-->F -D-->F -``` +The executor is a thread pool (`concurrent.futures.ThreadPoolExecutor`), with the number of threads determined by the `capacity` parameter. The setting of `capacity` greatly impacts performance and needs to be tailored based on specific tasks. +To enable concurrent execution of various agents within the server, it is best to ensure that the `capacity` is greater than the number of agents running simultaneously in `AgentServerServicer`. Otherwise, this may lead to exponential increases in execution time, or even deadlocks in certain scenarios (such as recursive calls among multiple agents). -Specifically, `B` and `C` can start execution simultaneously after receiving the message from `A`, and `E` can run immediately without waiting for `A`, `B`, `C`, and `D`. -By implementing each Agent as an Actor, an Agent will automatically wait for its input `Msg` before starting to execute the `reply` method, and multiple Agents can also automatically execute `reply` at the same time if their input messages are ready, which avoids complex parallel control and makes things simple. +The `capacity` parameter can be specified in the `as_server` command via `--capacity`, or directly during the initialization of `RpcAgentServerLauncher`. -### PlaceHolder - -Meanwhile, to support centralized application orchestration, AgentScope introduces the concept of {class}`Placeholder`. -A Placeholder is a special message that contains the address and port number of the agent that generated the placeholder, which is used to indicate that the output message of the Agent is not ready yet. -When calling the `reply` method of a distributed agent, a placeholder is returned immediately without blocking the main process. -The interface of placeholder is exactly the same as the message, so that the orchestration flow can be written in a centralized way. -When getting values from a placeholder, the placeholder will send a request to get the real values from the source agent. -A placeholder itself is also a message, and it can be sent to other agents, and let other agents to get the real values, which can avoid sending the real values multiple times. +```python +# ... +launcher = RpcAgentServerLauncher( + host="localhost", + port=12345, + custom_agent_classes=[], + capacity=10, +) +``` -About more detailed technical implementation solutions, please refer to our [paper](https://arxiv.org/abs/2402.14034). +```shell +as_server start --host localhost --port 12345 --model-config-path model_config_path --agent-dir parent_dir_of_myagents --capacity 10 +``` -### Agent Server +##### `result_pool` -In agentscope, the agent server provides a running platform for various types of agents. -Multiple agents can run in the same agent server and hold independent memory and other local states but they will share the same computation resources. +The `ResultPool` implementation is located in `src/agentscope/server/async_result_pool.py` and is used for managing the execution results of asynchronous methods. There are currently two implementations: `local` and `redis`. The `local` implementation is based on Python's dictionary type (`dict`), whereas the `redis` implementation is based on Redis. Both implementations include automatic deletion mechanisms to prevent results from consuming too much memory. The `local` implementation allows for timeout-based deletion (`max_expire`) or deletion when a certain number of items is exceeded (`max_len`), while the `redis` implementation only supports timeout-based deletion (`max_expire`). +During the startup of `AgentServerLauncher`, you can specify which implementation to use by passing in the `pool_type` parameter, with the default being `local`. +If `redis` is specified, you must also provide the `redis_url`. Below are examples of code and command-line usage. -After installing the distributed version of AgentScope, you can use the `as_server` command to start the agent server, and the detailed startup arguments can be found in the documentation of the {func}`as_server` function. +```python +# ... +launcher = RpcAgentServerLauncher( + host="localhost", + port=12345, + custom_agent_classes=[], + pool_type="redis", + redis_url="redis://localhost:6379", + max_expire_time=7200, # 2 hours +) +``` -As long as the code is not modified, an agent server can provide services for multiple main processes. -This means that when running mutliple applications, you only need to start the agent server for the first time, and it can be reused subsequently. +```shell +as_server start --host localhost --port 12345 --model-config-path model_config_path --agent-dir parent_dir_of_myagents --pool-type redis --redis-url redis://localhost:6379 --max-expire-time 7200 +``` [[Back to the top]](#208-distribute-en) diff --git a/docs/sphinx_doc/zh_CN/source/tutorial/208-distribute.md b/docs/sphinx_doc/zh_CN/source/tutorial/208-distribute.md index d6fe031bc..805df4ab0 100644 --- a/docs/sphinx_doc/zh_CN/source/tutorial/208-distribute.md +++ b/docs/sphinx_doc/zh_CN/source/tutorial/208-distribute.md @@ -2,422 +2,475 @@ # 分布式 -AgentScope实现了基于Actor模式的智能体分布式部署和并行优化，并提供以下的特点： +为了提供更好的性能以及支持更多的 Agent 同时运行，AgentScope 实现了基于 Actor 范式的 并行/分布式模式（后续简称为分布式模式）。该模式相比传统单进程模式具有以下特点： -- **自动并行优化**：运行时自动实现应用并行优化，无需额外优化成本； -- **应用编写中心化**：无需分布式背景知识，轻松编排分布式应用程序流程； -- **零成本自动迁移**：中心化的Multi-Agent应用可以轻松转化成分布式模式 +- **高性能**: 同一应用中的不同 Agent 以及其他服务可以运行不同进程甚至不同机器上，充分利用计算资源释放性能。 +- **自动并行化**: 基于 Actor 模式，每个 Agent都具有独立的状态，在编写应用时无需考虑调用顺序、资源竞争等问题，自动实现应用并行化。 +- **零迁移成本**: 代码与单机模式完全兼容，单机模式可运行的应用可以零成本直接迁移至并行/分布式模式。 -本教程将详细介绍AgentScope分布式的实现原理和使用方法。 +本节将详细介绍 AgentScope 分布式的使用方法并阐述其原理。 -## 使用方法 +(basic_usage-zh)= -AgentScope中，我们将运行应用流程的进程称为**主进程 (Main Process)**，而所有的智能体都会运行在额外的 **智能体服务器进程 (Agent Server Process)** 中。 -根据主进程与智能体服务器进程之间的关系，AgentScope 为每个 Agent 提供了两种启动模式：**子进程模式 (Child)** 和 **独立进程模式 (Indpendent)**。 -子进程模式中，开发者可以从主进程中启动所有的智能体服务器进程，而独立进程模式中，智能体服务器进程相对主进程来说是独立的，需要在对应的机器上启动智能体服务器进程。 +## 基础用法 -上述概念有些复杂，但是不用担心，对于应用开发者而言，仅需将已有的智能体转化为对应的分布式版本，其余操作都和正常的单机版本完全一致。 -

name="A", - # ... -).to_dist( - host="ip_a", - port=12001, -) -b = AgentB( - name="B", - # ... -).to_dist( - host="ip_b", - port=12002, -) +# 请不要使用 jupyter notebook 运行该代码 +# 请将代码拷贝到 `dist_server.py` 文件后使用 `python dist_server.py` 命令运行该代码, 目录结构如下： +# your_project_dir +# ├── dist_main.py +# └── dist_server.py +# 运行该代码前请先安装 agentscope 的分布式版本 +# pip install agentscope[distribute] + +import agentscope +from agentscope.server import RpcAgentServerLauncher +from dist_main import WebAgent + + +if __name__ == "__main__": + agentscope.init( + # model_configs=... # 模型配置，如果不需要模型，可以不设置该参数 + ) + assistant_server_launcher = RpcAgentServerLauncher( + host="localhost", + port=12345, + custom_agent_classes=[WebAgent], + ) + assistant_server_launcher.launch(in_subprocess=False) + assistant_server_launcher.wait_until_terminate() ``` -上述代码将会把 `AgentA` 部署到 `Machine1` 的智能体服务器进程上，并将 `AgentB` 部署到 `Machine2` 的智能体服务器进程上。 -开发者在这之后只需要用中心化的方法编排各智能体的交互逻辑即可。 +上述代码中，我们通过 `RpcAgentServerLauncher` 启动了一个智能体服务器进程，需要注意的是由于 `WebAgent` 不是 AgentScope 自带的 Agent 实现，需要将 `WebAgent` 添加到 `custom_agent_classes` ，才能在智能体服务器进程中创建该类型的 Agent。另外如果智能体服务器进程中需要使用模型 API，则需要在 `agentscope.init` 中配置对应的模型参数。 -### 步骤2: 编排分布式应用流程 +同时还需要将 `dist_main.py` 中的 `init_with_dist` 更新为下面的代码： -> Note: -> 当前分布式版本的 Agent 仅支持 `__call__` 方法调用 (即 `agent(x)`)，不支持调用其他方法或是属性读写。 +```python +def init_with_dist(): + return [WebAgent(f"W{i}").to_dist(host="localhost", port=12345) for i in range(len(URLS))] +``` -在AgentScope中，分布式应用流程的编排和非分布式的程序完全一致，开发者可以用中心化的方式编写全部应用流程。 -同时，AgentScope允许本地和分布式部署的智能体混合使用，开发者不用特意区分哪些智能体是本地的，哪些是分布式部署的。 +这里新版本的 `init_with_dist` 相比原版本新增了 `host` 与 `port` 两个参数，用于连接智能体服务器进程。 + +在代码修改完成后，先在一个命令行窗口中运行 `dist_server.py` 文件，等待启动成功后在另一个命令行窗口运行 `dist_main.py` 文件，运行的时候会看到如下输出： + +```text +初始化的耗时：0.005397319793701172 +[W0] Answer from page_1 +[W1] Answer from page_2 +[W2] Answer from page_3 +[W3] Answer from page_4 +[W4] Answer from page_5 +不使用分布式模式的耗时：25.023009061813354 +[W0] Answer from page_1 +[W1] Answer from page_2 +[W2] Answer from page_3 +[W3] Answer from page_4 +[W4] Answer from page_5 +使用分布式模式的耗时：5.021481990814209 +``` -以下是不同模式下实现两个智能体之间进行对话的全部代码，对比可见，AgentScope支持零代价将分布式应用流程从中心化向分布式迁移。 +此时的 `dist_main.py` 初始化的耗时将会明显减少，例如这里的耗时仅为 0.005 s。 -- 智能体全部中心化： +### 避免重复初始化 -```python -# 创建智能体对象 -a = AgentA( - name="A", - # ... -) +上面的代码中都是在一个已经初始化完成的 Agent 上调用 `to_dist` 函数。 +`to_dist` 本质上是将原 Agent 克隆到智能体服务器进程中，并在主进程中保留一个 {class}`RpcObject` 作为原 Agent 的代理，对该 `RpcObject`的调用都会转发到智能体服务器进程中的对应 Agent 上。 -b = AgentB( - name="B", - # ... -) +这样的流程存在一个潜在问题，即原 Agent 被初始化了两次，一次是在主进程中，一次是在智能体服务器进程中，并且这两次初始化是依次执行的，无法通过并行加速。对于初始化成本比较低的 Agent，直接调用 `to_dist` 函数不会对性能产生明显影响，但是对于初始化成本较高的 Agent，则需要尽量避免重复初始化行为，为此 AgentScope 分布式模式提供了另一种分布式模式的初始化方法，即直接在任意 Agent 的初始化函数内部传入 `to_dist` 参数，例如下面的代码就是对 `dist_main.py` 的`init_with_dist` 函数的修改。 -# 应用流程编排 -x = None -while x is None or x.content == "exit": -

x = a(x) - x = b(x) +```{note} +一些 IDE 的自动补全功能可能提示 `to_dist` 参数不存在，但实际运行时并不会报错。 +另外，如果已经在初始化参数中传入了 `to_dist`，则不能再调用 `to_dist` 方法。 ``` -### 进阶用法 +## 开发者指南 -#### 更低成本的 `to_dist` +```{note} +本节主要面向基于 AgentScope 分布式模式开发新功能的开发者，需要开发者有一定的分布式编程基础，对进程、线程、同步、异步、gRPC、Python 元类以及GIL等概念有一定的理解。但即使没有上述基础，通过阅读本节也能学到 AgentScope 分布式模式的基本原理以及一些高级用法。 +``` -上面介绍的案例都是将一个已经初始化的 Agent 通过 {func}`to_dist` 方法转化为其分布式版本，相当于要执行两次初始化操作，一次在主进程中，一次在智能体进程中。如果 Agent 的初始化过程耗时较长，直接使用 `to_dist` 方法会严重影响运行效率。为此 AgentScope 提供了在初始化 Agent 实例的同时将其转化为其分布式版本的方法，即在原 Agent 实例初始化时传入 `to_dist` 参数。 +AgentScope 分布式模式的主要逻辑是: -子进程模式下，只需要在 Agent 初始化函数中传入 `to_dist=True` 即可： +**将原本运行在任意 Python 进程中的对象通过 `to_dist` 函数或是初始化参数转移到 RPC 服务器中运行，并在原进程中保留一个 `RpcObject` 作为代理，任何 `RpcObject` 上的函数调用或是属性访问都会转发到 RPC 服务器中的对象上，并且在调用函数时可以自行决定是使用同步调用还是异步调用。** -```python -# Child Process mode -a = AgentA( - name="A", - # ... - to_dist=True -) -b = AgentB( - name="B", - # ... - to_dist=True -) +下图展示了`to_dist`初始化、同步函数调用以及异步函数调用的交互流程： + +```{mermaid} +sequenceDiagram + User -->> Process: initialize + Process -->> RPC Server: to_dist + User -->> Process: sync function call + Process -->> RPC Server: sync function call + RPC Server -->> RPC Server: calculate result + RPC Server -->> Process: sync result + Process -->> User: sync result + User -->> Process: async function call + Process -->> RPC Server: async function call + RPC Server -->> RPC Server: calculate result + User -->> Process: get async result + Process -->> RPC Server: get async result + RPC Server -->> Process: async result + Process -->> User: async result ``` -独立进程模式下， 则需要将原来 `to_dist()` 函数的参数以 {class}`DistConf` 实例的形式传入 Agent 初始化函数的 `to_dist` 域： +从上图可以观察到 AgentScope 分布式模式本质是一个 Client-Server 架构，用户编写的智能体应用（Process）作为Client 端，而智能体服务器进程（RPC Server）作为 Server 端。分布式模式下 Client 端将本地的智能体发送到 Server 端运行，并将本地的函数调用以及属性访问转发到 Server 端，而 Server 端则负责接收 Client 端发送的对象，并接收 Client 端发来的各种调用请求。 -```python -a = AgentA( - name="A", - # ... - to_dist=DistConf( - host="ip_a", - port=12001, - ), -) -b = AgentB( - name="B", - # ... - to_dist=DistConf( - host="ip_b", - port=12002, - ), -) +```{note} +AgentScope 分布式模式中 Client 与 Server 通信基于 gRPC 实现，对发送消息的大小有严格的限制，默认情况下单条消息不能超过 32 MB。可以通过修改 `src/agentscope/constants.py` 中的 `_DEFAULT_RPC_OPTIONS` 参数来进一步扩大该值。 ``` -相较于原有的 `to_dist()` 函数调用，该方法只会在智能体进程中初始化一次 Agent，避免了重复初始化行为，能够有效减少初始化开销。 +接下来将分别介绍 Client 端以及 Server 端的实现。 -#### 管理 Agent Server +### Client 端 -在运行大规模多智能体应用时，往往需要启动众多的 Agent Server 进程。为了让使用者能够有效管理这些进程，AgentScope 在 {class}`RpcAgentClient` 中提供了如下管理接口： +Client 主要包含 `RpcMeta`、`RpcObject` 两个主要类，其中 `RpcMeta` 负责将本地对象发送到 Server 端运行，而 `RpcObject` 则负责后续的各种请求调用的转发。 -- `is_alive`: 该方法能够判断该 Agent Server 进程是否正在运行。 +#### `RpcMeta` - ```python - client = RpcAgentClient(host=server_host, port=server_port) - if client.is_alive(): - do_something() - ``` +{class}`RpcMeta` 类是一个元类(Meta class)，会自动向继承自己的子类添加 `to_dist` 方法以及 `to_dist` 初始化参数 (因此 IDE 可能会提示 `to_dist` 参数不存在，但实际运行时并不会报错)，其实现位于 `src/agentscope/rpc/rpc_meta.py`。 -- `stop`: 该方法能够停止连接的 Agent Server 进程。 +在一个已经初始化完成的对象上调用 `to_dist` 方法会将原对象的初始化参数打包发送到 智能体服务器进程 中，并在智能体服务器进程中重新初始化该对象，而在主进程中会返回一个 `RpcObject` 替代原有的对象。 - ```python - client.stop() - assert(client.is_alive() == False) - ``` +由于是使用初始化参数来重建原有对象，无法维持创建后的状态变化，因此建议在初始化的同时立即调用 `to_dist` 方法，或者直接在原对象的初始化函数中传入 `to_dist` 参数。 -- `get_agent_list`: 该方法能够获取该 Agent Server 进程中正在运行的所有 Agent 的 JSON 格式的缩略信息列表，具体展示的缩略信息内容取决于该 Agent 类的 `__str__` 方法。 +由于 `to_dist` 是 `RpcMeta` 自动向子类添加的方法，因此不仅是 Agent 类，任何继承自 `RpcMeta` 的类都可以使用 `to_dist` 方法。 - ```python - agent_list = client.get_agent_list() - print(agent_list) # [agent1_info, agent2_info, ...] - ``` +`RpcMeta` 除了提供 `to_dist` 方法外还会记录原对象上能够被调用的方法以及属性，以方便在 `RpcObject` 中调用。默认情况下只会记录原对象上的公有方法，并且使用同步调用 (调用时会阻塞调用发起方，直到原对象上的方法执行完毕)。如果需要使用异步调用需要在方法声明上添加 `async_func` 装饰器。 -- `get_agent_memory`: 该方法能够获取指定 `agent_id` 对应 Agent 实例的 memory 内容。 +#### `async_func` 和 `AsyncResult` - ```python - agent_id = my_agent.agent_id - agent_memory = client.get_agent_memory(agent_id) - print(agent_memory) # [msg1, msg2, ...] - ``` +{func}`async_func` 装饰器的实现位于 `src/agentscope/rpc/rpc_meta.py``AgentBase` 及其所有子类的 `__call__` 以及 `reply` 方法都被标记为了 `async_func` 以避免阻塞。 -- `get_server_info`：该方法能够获取该 Agent Server 进程的资源占用情况，包括 CPU 利用率、内存占用。 +与 `async_func` 相对的还有 {func}`sync_func` 装饰器，用于标识同步方法。但由于同步方法为默认情况，因此一般不使用。 - ```python - server_info = client.get_server_info() - print(server_info) # { "cpu": xxx, "mem": xxx } - ``` +如下是一个简单的示例，这里声明了一个 `Example` 类，其中 `sync_method` 是同步方法，`async_method_basic` 以及 `async_method_complex` 被标记为了异步方法，`_protected_method` 是私有方法。 -- `set_model_configs`: 该方法可以将指定的模型配置信息设置到 Agent Server 进程中，新创建的 Agent 实例可以直接使用这些模型配置信息。 +```python +import time +from agentscope.rpc import RpcMeta, async_func + + +class Example(metaclass=RpcMeta): + + # @sync_func # 默认即为 sync_func，可以不添加 + def sync_method(self) -> str: + # 同步方法，调用者会被阻塞 1 s + time.sleep(1) + return "sync" + + @async_func + def async_method_basic(self) -> str: + # 异步方法，调用者不会被阻塞，可以继续执行直到尝试获取结果 + time.sleep(1) + # 返回一个基本类型 + return "async" + + @async_func + def async_method_composite(self) -> dict: + # 异步方法 + time.sleep(1) + # 返回一个字典 + return {"a": 1, "b": 2, "c": "hello world",} + + def _protected_method(self) -> str: + # 不是公有方法，rpc object 无法调用该方法 + time.sleep(1) + return "protected" + + +if __name__ == "__main__": + example = Example(to_dist=True) + # 访问 protected 方法会引发未定义行为，请避免使用 + # protected_result = example._protected_method() + t1 = time.time() + sync_result = example.sync_method() + assert sync_result == "sync" + t2 = time.time() + print(f"Sync func cost: {t2 - t1} s") + t3 = time.time() + async_basic = example.async_method_basic() + async_composite = example.async_method_composite() + t4 = time.time() + print(f"Async func cost: {t4 - t3} s") + # 基本类型需要在返回值上调用 result 方法获取异步执行结果 + assert async_basic.result() == "async" + # 复合类型在访问所需要的域时自动更新异步执行结果 + assert async_composite["a"] == 1 + assert async_composite["b"] == 2 + assert async_composite["c"] == "hello world" +``` - ```python - agent = MyAgent( # 因为找不到 [my_openai] 模型而失败 - # ... - model_config_name="my_openai", - to_dist={ - # ... - } - ) - client.set_model_configs([{ # 新增 [my_openai] 模型配置信息 - "config_name": "my_openai", - "model_type": "openai_chat", - # ... - }]) - agent = MyAgent( # 成功创建 Agent 实例 - # ... - model_config_name="my_openai", - to_dist={ - # ... - } - ) - ``` +上述代码的运行结果样例如下，可以观察到调用 `async_method` 的耗时比 `sync_method` 短很多，这是因为 `async_method` 是异步方法，不会阻塞调用发起方，而 `sync_method` 是同步方法，因此会阻塞调用发起方。 -- `delete_agent`: 该方法用于删除指定 `agent_id` 对应的 Agent 实例。 +```text +Sync func cost: 1.0073761940002441 s +Async func cost: 0.0003597736358642578 s +``` - ```python - agent_id = agent.agent_id - ok = client.delete_agent(agent_id) - ``` +上述代码中 `async_method_basic` 以及 `async_method_complex` 返回的是 {class}`AsyncResult` 对象，该对象可以通过 `result` 方法获取异步执行结果。为了让异步与同步调用的接口尽可能统一，如果 `AsyncResult` 所代表的结果是复合类型，就不再需要手动调用 `result` 方法，在访问内部属性时会自动调用 `result` 更新执行结果 (如上述代码中 `async_composite` 所示)。 -- `delete_all_agent`: 该方法可以删除 Agent Server 进程中所有的 Agent 实例。 +#### `RpcObject` - ```python - ok = client.delete_all_agent() - ``` +{class}`RpcObject` 的实现位于 `src/agentscope/rpc/rpc_object.py` 中。 +`RpcObject` 是一个代理，其内部并不包含原对象的任何属性值或是方法，只记录了原对象所在的智能体服务器的地址以及该对象的 `id`，通过这些参数，`RpcObject` 可以通过网络连接原对象，从而实现对原对象的调用。 -#### 连接 AgentScope Studio +当用户调用 `RpcObject` 上的方法或访问属性时，`RpcObject` 会通过 `__getattr__` 方法将请求转发到位于智能体服务器进程的原对象上。对于调用同步方法 (`@sync_func`) 或是访问属性值的情况，`RpcObject` 会阻塞调用发起方，直到原对象上的方法执行完毕，并返回执行结果。而异步方法 (`@async_func`) 则会立即返回一个 {class}`AsyncResult` 对象，如果主进程不去访问该对象的具体值就可以无阻塞地继续运行，而如果需要获取执行结果，则需要调用 `AsyncResult` 对象上的 `result` 方法，如果此时结果还没有返回，`result` 方法会阻塞调用发起方，直到结果返回。 -智能体服务器进程可以在启动时连接 [AgentScope Studio](#209-gui-zh) ，从而让后续搭建的分布式应用中的 `to_dist` 方法不再需要填写任何参数，而是由 Stduio 为其自动分配智能体服务器进程。 +```{note} +`RpcObject` 在初始化时如果发现没有提供 `host` 和 `port` 参数 (即子进程模式)，就会去启动一个新的智能体服务器进程，并在该进程上重新创建原对象，而启动新的智能体服务器进程相对缓慢，这也是导致子进程模式初始化时间较长的主要原因。 +而如果提供了 `host` 和 `port` 参数 (即独立进程模式)，`RpcObject` 就会直接连接该服务器并重新创建原对象，避免了启动新进程的开销。 +``` -对于使用 Python 代码启动智能体服务器进程的场景，只需要在 `RpcAgentServerLauncher` 的初始化参数中填入 `studio_url` 即可，这里需要确保填写正确且能够通过网络访问，例如默认情况下启动的 Studio 的 URL 为 `http://127.0.0.1:5000`。 +### Server 端 -```python -# import some packages +Server 端主要基于 gRPC 实现，主要包含 `AgentServerServicer` 和 `RpcAgentServerLauncher` 这两个类。 -# register models which can be used in the server -agentscope.init( - model_configs=model_config_path_a, -) -# Create an agent service process -server = RpcAgentServerLauncher( - host="ip_a", - port=12001, # choose an available port - custom_agent_classes=[...] # register your customized agent classes - studio_url="http://studio_ip:studio_port", # connect to AgentScope Studio -) +#### `AgentServerLauncher` -# Start the service -server.launch() -server.wait_until_terminate() -``` +`AgentServerLauncher` 的实现位于 `src/agentscope/server/launcher.py`，用于启动 gRPC Server 进程。 +具体来说，为了保证启动的 Server 进程中能够正确地重新初始化 Client 端发来的对象并正确调用模型API服务，需要在启动 Server 时注册在运行中可能用到的所有 `RpcMeta` 的子类，并且正确设置模型配置。具体来说有两种启动方法，分别是通过代码启动，和通过命令行指令启动。 -对于使用命令行 `as_server` 的场景，也只需要在命令行中填入 `--studio-url` 参数。 +- 通过代码启动的具体方法如下，需要指定 `host` 和 `port`，以及 `custom_agent_classes`，并且需要在调用 `agentscope.init` 时传入需要使用的模型配置。这里假设有 `AgentA`，`AgentB`，`AgentC` 这三个自定义类需要被注册，并且 `AgentA`，`AgentB`，`AgentC` 这三个类都位于 `myagents.py` 文件中且都是 `AgentBase` 的子类。 -```shell -as_server --host ip_a --port 12001 --model-config-path model_config_path_a --agent-dir parent_dir_of_agent_a_and_b --studio-url http://studio_ip:studio_port -``` + ```python + import agentscope + from agentscope.server import RpcAgentServerLauncher + from myagents import AgentA, AgentB, AgentC -执行上述代码或命令后可以进入 AgentScope Studio 的 Server Manager 页面查看是否连接成功。如果连接成功，该智能体服务器进程会显示在页面的表格中，并且可以在页面中观察到该进程的运行状态以及资源占用情况，之后就可以使用 AgentScope Studio 所带来的高级功能了。本节将聚焦于 AgentScope Studio 对 `to_dist` 方法带来的影响，而页面的具体用法请参考 [AgentScope Studio](#209-gui-zh)。 -在智能体服务器进程成功连接 Studio 后，只需要在 `agentscope.init` 方法中传入该 Studio 的 `studio_url`，后续的 `to_dist` 方法就不再需要填写 `host` 和 `port` 域，而是自动选择一个已经连接到 Studio 的智能体服务器进程。 + MODEL_CONFIGS = {} -```python -# import some packages + HOST = "localhost" + PORT = 12345 + CUSTOM_CLASSES = [AgentA, AgentB, AgentC] -agentscope.init( -

name="A" - # ... -).to_dist() # automatically select an agent server +- 通过命令行启动的具体方法如下，除了需要指定 `host` 和 `port` 外，还需要指定 `model_config_path` 和 `agent_dir`，分别对应模型配置文件路径和自定义 Agent 类所在的目录。在安装 `agentscope` 时默认会安装 `as_server` 指令，所以可以直接在命令行中使用该指令。 -# your application code -``` + ```shell + as_server start --host localhost --port 12345 --model-config-path model_config_path --agent-dir parent_dir_of_myagents.py + ``` -> Note: -> -> - 该方法中使用的 Agent 必须在智能体服务器进程启动时就已经通过 `custom_agent_classes` 或 `--agent-dir` 注册。 -> - 使用该方法时需要确定连接到 Studio 的智能体服务器进程还在正常运行。 +```{warning} +`AgentServerLauncher` 会加载并执行自定义的 Python 对象，在使用前请仔细检查被加载的对象，如果其中包含恶意代码可能会对系统造成严重损害。 +`AgentServerLauncer` 类还存在一个 `local_mode` 参数用于表示是否只允许本地访问，默认为 `True`，如果需要允许其他机器访问，则需要设置为 `False`。为了避免网络攻击，建议仅在可信的网络环境下使用。 +``` -在应用开始运行后，可以在 Studio 的 Server Manager 页面中观察该 Agent 具体运行在哪个智能体服务器进程上，应用运行完成后也可以通过 Server Manager 页面删除该 Agent。 +#### `AgentServerServicer` -## 实现原理 +`AgentServerServicer` 的实现位于 `src/agentscope/server/servicer.py`，是 gRPC 服务的实现类，负责具体接收并处理 Client 端发来的各种请求。 -### Actor模式 +其中的 `create_agent` 方法会在 Client 端对某个 `RpcMeta` 的子类对象使用 `to_dist` 时被调用，并在 server 内部重新创建原对象，并以 `id` 为键将对象保存在 `agent_pool` 域中。 -[Actor模式](https://en.wikipedia.org/wiki/Actor_model)是大规模分布式系统中广泛使用的编程范式，同时也被应用于AgentScope平台的分布式设计中。 -在Actor模型中，一个actor是一个实体，它封装了自己的状态，并且仅通过消息传递与其他actor通信。 +而 `call_agent_func` 方法会在 Client 端调用 `RpcObject` 对象上的方法或属性时被调用，输入参数中包含了被调用对象的 `id` 以及被调用方法的名称，具体的调用流程有一定差异。对于同步方法以及属性访问，`call_agent_func` 会直接从 `agent_pool` 取出对象并调用对应方法或属性，并在返回结果前阻塞调用发起方。对于异步方法，`call_agent_func` 会将输入参数打包放入任务队列中，并立即返回该任务的 `task_id` 从而避免阻塞调用发起方。 -在AgentScope的分布式模式中，每个Agent都是一个Actor，并通过消息与其他Agent交互。消息的流转暗示了Agent的执行顺序。每个Agent都有一个`reply`方法，它消费一条消息并生成另一条消息，生成的消息可以发送给其他 Agent。例如，下面的图表显示了多个Agent的工作流程。`A`~`F`都是Agent，箭头代表消息。 +`AgentServerServicer` 内部包含了一个执行器池 (`executor`) 用于自动执行任务队列中提交的任务 (`_process_task`)，并执行将结果放入 `result_pool` 中，`AsyncResult` 的 `result` 方法会尝试从 `result_pool` 中取出对应任务的结果，如果任务结果不存在则会阻塞调用发起方，直到结果返回。 -```{mermaid} -graph LR; -A-->B -A-->C -B-->D -C-->D -E-->F -D-->F -``` +##### `executor` -其中，`B`和`C`可以在接收到来自`A`的消息后同时启动执行，而`E`可以立即运行，无需等待`A`、`B`、`C`和`D`。 -通过将每个Agent实现为一个Actor， Agent将自动等待其输入Msg准备好后开始执行`reply`方法，并且如果多个 Agent 的输入消息准备就绪，它们也可以同时自动执行`reply`，这避免了复杂的并行控制。 +executor 是一个线程池 (`concurrent.futures.ThreadPoolExecutor`)，其中的线程数量由 `capacity` 参数决定，`capacity` 的设置对运行效率的影响巨大，需要根据具体任务来针对性设置。 +为了让 Server 中的各个 Agent 能够并发执行，最好保证 `capacity` 大于 `AgentServerServicer` 中同时运行的 Agent 的数量，否则可能会导致运行时间成倍增加，甚至在一些特殊场景 (多个agent 之间进行递归调用) 中出现死锁现象。 -#### Placeholder +`capacity` 参数可以在 `as_server` 命令中通过 `--capacity` 指定，或是直接在 `RpcAgentServerLauncher` 初始化时指定。 -同时，为了支持中心化的应用编排，AgentScope 引入了 {class}`Placeholder` 这一概念。 -Placeholder 可以理解为消息的指针，指向消息真正产生的位置，其对外接口与传统模式中的消息完全一致，因此可以按照传统中心化的消息使用方式编排应用。 -Placeholder 内部包含了该消息产生方的联络方法，可以通过网络获取到被指向消息的真正值。 -每个分布式部署的 Agent 在收到其他 Agent 发来的消息时都会立即返回一个 Placeholder，从而避免阻塞请求发起方。 -而请求发起方可以借助返回的 Placeholder 在真正需要消息内容时再去向原 Agent 发起请求，请求发起方甚至可以将 Placeholder 发送给其他 Agent 让其他 Agent 代为获取消息内容，从而减少消息真实内容的不必要转发。 +```python +# ... +launcher = RpcAgentServerLauncher( + host="localhost", + port=12345, + custom_agent_classes=[], + capacity=10, +) +``` -关于更加详细的技术实现方案，请参考我们的[论文](https://arxiv.org/abs/2402.14034)。 +```shell +as_server start --host localhost --port 12345 --model-config-path model_config_path --agent-dir parent_dir_of_myagents --capacity 10 +``` -### Agent Server +##### `result_pool` -Agent Server 也就是智能体服务器。在 AgentScope 中，Agent Server 提供了一个让不同 Agent 实例运行的平台。多个不同类型的 Agent 可以运行在同一个 Agent Server 中并保持独立的记忆以及其他本地状态信息，但是他们将共享同一份计算资源。 +`ResultPool` 的实现位于 `src/agentscope/server/async_result_pool.py`，用于管理异步方法的执行结果，目前有两种实现分别为 `local` 和 `redis`。其中 `local` 基于 Python 的字典类型 (`dict`) 实现，而 `redis` 则是基于 Redis 实现。为了避免结果占用过多内存两种实现都包含了过期自动删除机制，其中 `local` 可以设置超时删除 (`max_expire`) 或超过条数删除 (`max_len`)，而 `redis` 则仅支持超时删除 (`max_expire`)。 +在启动 `AgentServerLauncher` 时可以通过传入 `pool_type` 来指定使用哪种实现，默认为`local`。 +如果指定为 `redis` 则还必须传入 `redis_url`，如下是代码以及命令行的使用案例。 -在安装 AgentScope 的分布式版本后就可以通过 `as_server` 命令来启动 Agent Server，具体的启动参数在 {func}`as_server` 函数文档中可以找到。 +```python +# ... +launcher = RpcAgentServerLauncher( + host="localhost", + port=12345, + custom_agent_classes=[], + pool_type="redis", + redis_url="redis://localhost:6379", + max_expire_time=7200, # 2 hours +) +``` -只要没有对代码进行修改，一个已经启动的 Agent Server 可以为多个主流程提供服务。 -这意味着在运行多个应用时，只需要在第一次运行前启动 Agent Server，后续这些 Agent Server 进程就可以持续复用。 +```shell +as_server start --host localhost --port 12345 --model-config-path model_config_path --agent-dir parent_dir_of_myagents --pool-type redis --redis-url redis://localhost:6379 --max-expire-time 7200 +``` [[回到顶部]](#208-distribute-zh) diff --git a/examples/distributed_parallel_optimization/main.py b/examples/distributed_parallel_optimization/main.py index 5a847cd6d..ce057a4f8 100644 --- a/examples/distributed_parallel_optimization/main.py +++ b/examples/distributed_parallel_optimization/main.py @@ -53,7 +53,7 @@ def parse_args() -> argparse.Namespace: model_config_name="my_model", ) if args.use_dist: -

Let's discuss the key components for an engaging open-world game. Bob, could you share your thoughts on the game mechanics and systems? +Alice: Hey everyone! I've been thinking about the open world game we're working on. It would be great if we could gather some ideas for unique NPC behaviors that would add depth to our world. @Carol, do you have any specific scenarios or character types in mind that you think would fit well into our game environment? +2024-08-22 15:35:51.633 | INFO | envs.chatroom:__call__:228 - Alice mentioned Carol. +Bob: Sure, for the game mechanics, I think incorporating dynamic weather systems and time of day changes could enhance player immersion. This way, NPC activities and environments adapt accordingly, creating a more realistic experience. @Alice, what kind of NPC behaviors were you envisioning? Could they interact differently based on the current weather or time of day? +2024-08-22 15:35:54.194 | INFO | envs.chatroom:__call__:228 - Bob mentioned Alice. +Carol: Absolutely, integrating dynamic NPC behaviors based on the environment and time of day sounds intriguing. For example, we could have traders setting up their stalls only during certain hours, or farmers tending to their crops in daylight but resting under the stars. @Bob, how do you think we could implement these mechanics to ensure they don't feel too repetitive for players over time? +2024-08-22 15:36:02.657 | INFO | envs.chatroom:__call__:228 - Carol mentioned Bob. +Alice: Absolutely, I was thinking along those lines as well. For example, fishermen might have better luck during certain times of day or under specific weather conditions. Farmers could have urgent tasks depending on the season or weather forecasts. And maybe traders would have special items to sell or deals to offer at night or during festivals. What do you think, @Bob? +2024-08-22 15:36:03.409 | INFO | envs.chatroom:__call__:228 - Alice mentioned Bob. +Bob: I think those ideas are fantastic! To avoid repetition, we could introduce random events or quests that trigger based on the time of day or weather conditions. This would keep the gameplay fresh and engaging. Additionally, NPC preferences could change seasonally, adding another layer of complexity. For instance, a fisherman might prefer fishing during high tide, which could vary by season. I believe these dynamic elements will significantly enrich the player's experience. Let's brainstorm some specific examples and scenarios to flesh out these ideas further. +Carol: Great suggestions, everyone! Let's start documenting these ideas and create a detailed list. We'll also need to consider how these mechanics impact the game's overall narrative and pacing. Once we have a solid foundation, we can move on to designing the visual aspects and user interface. @Alice, can you give us some preliminary thoughts on how we might visually represent these dynamic changes in the game world? +2024-08-22 15:36:14.411 | INFO | envs.chatroom:__call__:228 - Carol mentioned Alice. +Alice: Great suggestion, @Bob! I agree that introducing seasonal changes and random events will make the game world more alive and interesting. Let's consider having a festival once a month where NPCs participate in unique activities, like a harvest festival in autumn or a winter market with special winter-only goods. We could also have natural disasters like storms or wildfires that affect the environment and NPC behavior, forcing players to adapt their strategies. What do you think about incorporating such unpredictable elements into our game design? +2024-08-22 15:36:15.903 | INFO | envs.chatroom:__call__:228 - Alice mentioned Bob. +Bob: Those are excellent ideas, @Alice! The festivals and natural disasters sound like they could really bring the world to life and challenge players in different ways. I'm particularly intrigued by the concept of festivals. Let's explore how we can integrate these events seamlessly into the game world and ensure they're both fun and immersive. @Carol, could you help us think about how these events might impact the overall narrative and quest progression? +2024-08-22 15:36:18.267 | INFO | envs.chatroom:__call__:228 - Bob mentioned Alice. +2024-08-22 15:36:18.268 | INFO | envs.chatroom:__call__:228 - Bob mentioned Carol. +Carol: Absolutely, integrating festivals and natural disasters will definitely add depth to the game world and provide unique challenges for players. These events can serve as pivotal points in the narrative, influencing storylines and quest objectives. For instance, a festival might require players to help prepare or manage specific aspects of the event, while a natural disaster could lead to emergent quests that involve rescue operations or rebuilding efforts. Let's outline how these events can be woven into the main storyline and side quests to maintain engagement throughout the game. +Alice: Absolutely, @Bob! Festivals and natural disasters can definitely add a lot of depth and excitement to the game. I think it's important to balance these elements so they don't overwhelm the player or disrupt the flow of the game too much. We should aim to make them integral parts of the story and questlines. For example, a festival could lead to a special quest where players help organize events or solve puzzles related to the festival. As for natural disasters, they could serve as obstacles that players must overcome, either by preparing for them or by finding creative solutions when they occur unexpectedly. Let's discuss how we can integrate these elements into our game design in a way that enhances the overall player experience. +2024-08-22 15:36:28.846 | INFO | envs.chatroom:__call__:228 - Alice mentioned Bob. +Bob: I think this plan is shaping up beautifully. Let's focus on creating detailed mechanics for festivals and disasters, ensuring they not only add to the gameplay but also enhance the storytelling. We can then move on to refining the NPC behaviors and integrating them with the environmental changes. @Carol, @Alice, let's schedule a meeting to go over these concepts in detail and start fleshing out the designs. Goodbye for now, everyone. Let's make sure to touch base soon with updates on our progress. +2024-08-22 15:36:30.553 | INFO | envs.chatroom:__call__:228 - Bob mentioned Alice. +2024-08-22 15:36:30.554 | INFO | envs.chatroom:__call__:228 - Bob mentioned Carol. +Carol: Great summary, Bob! Your plan aligns perfectly with our goals for enhancing player immersion and narrative depth. Let's indeed focus on festivals and disasters as key elements that will drive our game's dynamics. Scheduling that meeting sounds like a good idea to delve deeper into these concepts. I'll coordinate the details and send out a calendar invite shortly. Looking forward to our next steps and seeing how we can refine NPC behaviors and environmental interactions. Keep up the great work, everyone! Goodbye for now, and let's stay in touch for updates. +Alice: Great summary, Bob! I'm excited to dive deeper into these mechanics and NPC behaviors. Let's ensure we capture the essence of each festival and disaster, making them unique and memorable. Looking forward to the meeting and seeing everyone's ideas come to life.
