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If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc 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'
