Using NVIDIA's Windows cuDNN installer, the PATH entry looks like C:\Program Files\NVIDIA\CUDNN\v9.7\bin, but the libraries are in CUDA-version-specific subdirectories, i.e. C:\Program Files\NVIDIA\CUDNN\v9.7\bin\12.8\cudnn_ops64_9.dll. PATH lookups are not recursive, so any software expecting the DLL at the top level will fail.

You can add C:\Program Files\NVIDIA\CUDNN\v9.7\bin\12.8 to the PATH then restart the shell as a workaround.

Python ignores the Windows PATH completely since 3.8 (iirc). To get things to work I added the following to my main python file:

import os

os.add_dll_directory("c:\\Program Files\\NVIDIA\\CUDNN\\v9.7\\bin\\12.8")

Most likely faster-whisper (or a downstream dependency) is missing logic to detect the CUDA path, but this workaround should be fine until that's fixed.
