1、问题：

import yaml
ModuleNotFoundError: No module named 'yaml'

yaml模块的pip工具包名称不是yaml，而是pyyaml，所以不是直接pip install yaml，而是

pip install pyyaml

2、问题：

RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work
warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)RuntimeWarning: Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work
warn("Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work", RuntimeWarning)FileNotFoundError: [WinError 2] 系统找不到指定的文件

解决方法：

先打开Anaconda Prompt,输入如下命令：

conda install ffmpeg
pip install ffmpy

然后在输入如下代码测试是否安装成功

3、问题：

跑代码的时候遇到如下错误

TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:1. Downgrade the protobuf package to 3.20.x or lower.2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

解决方法:

按照提示的第一个，降级protoc即可：

pip install 'protobuf~=3.19.0'
