Description
currently trying to use whisperX (which uses faster whisper, which uses CTranslate2), and am getting the following error
Could not locate cudnn_ops_infer64_8.dll. Please make sure it is in your library path!
which from what I can tell is due to having CUDNN version > 9. This is an issue because it looks like pytorch >= 2.4.0 are compiled with CUDNN > 9.
See discussion here
https://github.com/SYSTRAN/faster-whisper/pull/958
Workaround right now is just to use a pytorch version < 2.4

Research direction
Start by reproducing the reported DLL error with PyTorch 2.4 or newer and CUDNN 9, then read the linked faster-whisper discussion for compatibility details. No source file or test is named; done means CTranslate2 runs with CUDNN 9 without requiring cudnn_ops_infer64_8.dll.
