langchain-Ollama-Chainlit

Simple Chat UI as well as chat with documents using LLMs with Ollama (mistral model) locally, LangChaiin and Chainlit

In these examples, we’re going to build a simpel chat UI and a chatbot QA app. We’ll learn how to:

Example 1

• Create a simple Chat UI locally.

Example 2

• Ingest documents into vector database, store locally (creates a knowledge base)
• Create a chainlit app based on that knowledge base.

Example 3

• Upload a document(pdf)
• Create vector embeddings from that pdf
• Create a chatbot app with the ability to display sources used to generate an answer

Chat with your documents 🚀

• Ollama and mistralas Large Language model
• LangChain as a Framework for LLM
• Chainlit for deploying.

System Requirements

You must have Python 3.9 or later installed. Earlier versions of python may not compile.

Steps to Replicate

1. Fork this repository and create a codespace in GitHub as I showed you in the youtube video OR Clone it locally.

git clone https://github.com/sudarshan-koirala/langchain-ollama-chainlit.git
cd langchain-ollama-chainlit

2. Rename example.env to .env with cp example.env .envand input the langsmith environment variables. This is optional.

3. Create a virtualenv and activate it

   python3 -m venv .venv && source .venv/bin/activate
   

4. Run the following command in the terminal to install necessary python packages:

   pip install -r requirements.txt
   

5. Run the following command in your terminal to start the chat UI:

   # Example 1
   chainlit run simple_chatui.py
   

   ---

   # Example 2
   python3 ingest.py
   chainlit run main.py
