关于ffmpeg拓展的问题，找不到4、5、6版本

[YamakiYume]

本地部署时，之前步骤一切正常，但一旦到训练阶段，就会不停报错关于ffmpeg拓展与调用等问题，每次的训练步骤是可以继续进行的，但最终结果相当糟糕。我有可以使用的ffmpeg编译完成的exe文件且环境配置正常。具体报错如下： Traceback (most recent call last): File "D:\Anaconda\Anaconda\envs\data_sci\lib\site-packages\torchaudio_extension\utils.py", line 128, in _find_ffmpeg_extension return _find_versionsed_ffmpeg_extension(ffmpeg_ver) File "D:\Anaconda\Anaconda\envs\data_sci\lib\site-packages\torchaudio_extension\utils.py", line 113, in _find_versionsed_ffmpeg_extension _try_access_avutil(ffmpeg_ver) File "D:\Anaconda\Anaconda\envs\data_sci\lib\site-packages\torchaudio_extension\utils.py", line 89, in _try_access_avutil torchaudio.lib._torchaudio.find_avutil(libavutil) RuntimeError DEBUG:torchaudio._extension.utils:Attempting to load FFmpeg version 5.

你装的FFmpeg的version是多少呢

[cythc]

同样的问题 ffmpeg6.1.1

同样的问题 ffmpeg6.1.1

请问最终怎么解决的呢？

[wlsekd]

try conda install -c conda-forge 'ffmpeg<7' or conda install ffmpeg=6 to install ffmpeg
