FFmpeg installation not detected with diart

Question

Here I'm using the diart library for audio transcription and the OpenAI Whisper model model.
When I run my code I get this error though

Traceback (most recent call last):
File "/home/vkyc/Desktop/projectRasa/audio/lib/python3.10/site- 
packages/torchaudio/_extension.py", line 71, in _init_ffmpeg
_load_lib("libtorchaudio_ffmpeg")
File "/home/vkyc/Desktop/projectRasa/audio/lib/python3.10/site- 
packages/torchaudio/_extension.py", line 52, in _load_lib

self._handle = _dlopen(self._name, mode)
OSError: libavdevice.so.58: cannot open shared object file: No such file or directory

The above exception was the direct cause of the following exception:

ImportError: FFmpeg libraries are not found. Please install FFmpeg.

I tried pip install python-ffmpeg andsudo apt install ffmpeg.
Although FFmpeg is installed on my system it still throws the same error.

What version of ffmpeg do you have installed? You can check with `ffmpeg --version` — ShadowCrafter_01, Jun 08 '23 at 09:09
You can try to install `libavdevice58` from apt directly (but it should be installed automatically with `ffmpeg`). — Stanislav Ivanov, Jun 08 '23 at 09:34

According to the PyTorch documentation the TorchAudio module supports FFmpeg version 4.1 - 4.4. If you build TorchAudio from the source FFmpeg 5 is supported.

Reinstall a supported FFmpeg version and then it should work. As you didn't provied any code I couldn't try it out though.
