Windows中使用torchaudio.io.StreamReader时报错：
FileNotFoundError: Could not find module 'D:\software\miniconda3\envs\pytorch\Lib\site-packages\torchaudio\lib\libtorchaudio_ffmpeg.pyd' (or one of its dependencies). Try using the full path with constructor syntax.
RuntimeError: StreamReader requires FFmpeg extension which is not available. Please refer to the stacktrace above for how to resolve this.
提示libtorchaudio_ffmpeg.pyd这个东西找不到，但是查看目录里明明是有的
我的解决方案
https://anaconda.org/conda-forge/ffmpeg
执行以下任意一条命令
conda install conda-forge::ffmpeg
conda install conda-forge/label/broken::ffmpeg
conda install conda-forge/label/cf201901::ffmpeg
conda install conda-forge/label/cf202003::ffmpeg
conda install conda-forge/label/gcc7::ffmpeg
参考
Torchaudio fails to find FFmpeg when installed via poetry #3195
TorchAudio does not pick up ffmpeg #3016
试图本地运行时出现DEBUG:torchaudio._extension:Failed to initialize ffmpeg bindings #144
