- 在Ubuntu上运行Python项目，首先安装anaconda，直接在官网安装就好了。然后装Pycharm，也是在官网上装对应的社区版，配置conda的虚拟环境。在复现vae的代码时，绘图不能呈现，出现下述问题。
解决方法：
① 先用pip list列出所有的库，然后uninstall删掉PYQT相关的库
② 再用pip install PYQT==5.15.1去安装，但此时会安装两个库，PYQT和PYQT-sip，再pip uninstall PYQT只保留一个QT相关库就可以正常运行画图相关代码了。
- 在Unreal Engine上加入Github开发团队，这样Github会发送邮箱确认，加入开发团队后就能够访问UE的开源代码。
- 进入文件夹，
cd UnrealEngine-4.26，然后运行安装程序./Setup.sh
安装中。
安装成功。
- 运行工程配置文件
./GenerateProjectFiles.sh
工程配置脚本运行成功。
- 编译UE4，使用
make命令
编译成功。
git clone对应的airsim Linux版本。cd AirSim运行./setup.sh
这个错误信息是因为Ubuntu无法找到"vulkan-utils"这个包。解决方案：
- 更新包列表：尝试使用以下命令更新您的系统包列表。
sudo apt-get update
然后再试着安装
- 手动添加软件源：如果更新包列表后问题仍然存在，可以试着手动添加Vulkan软件源。
先添加 key
wget -qO - http://packages.lunarg.com/lunarg-signing-key-pub.asc | sudo apt-key add -
然后添加到 apt source list
sudo wget -qO /etc/apt/sources.list.d/lunarg-vulkan-1.2.170-bionic.list http://packages.lunarg.com/vulkan/1.2.170/lunarg-vulkan-1.2.170-bionic.list
再更新一次包列表
sudo apt update
但是还是会出现问题：
(base) gh@gh-virtual-machine:~/AirSim$ ./setup.sh
+ set -e
+++ dirname ./setup.sh
++ cd .
++ pwd
+ SCRIPT_DIR=/home/gh/AirSim
+ pushd /home/gh/AirSim

- 更新软件包索引列表。在终端中运行以下命令：
sudo apt-get update- 更新软件包索引列表后仍然无法找到
vulkan-utils，更改/更新软件源。编辑/etc/apt/sources.list文件。备份当前 sources.list 文件，然后替换为默认内容。默认的 sources.list 文件应如下所示：
deb http://archive.ubuntu.com/ubuntu/ focal main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ focal-security main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ focal-updates main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ focal-proposed main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ focal-backports main restricted universe multiverse
使用文本编辑器打开并编辑此文件，如 sudo nano /etc/apt/sources.list ，并替换为上述内容，然后保存(ctrl+S)并关闭(ctrl+X)文件。
- 保存更改后，再次更新您的软件包索引列表：
sudo apt-get update- 然后再次尝试安装
vulkan-utils：
sudo apt-get install vulkan-utils
