RuntimeError: Failed to import native module _PyNvCodec! Please check whether "/home/kevin/anaconda3/lib/python3.11/site-packages/PyNvCodec/_PyNvCodec.cpython-311-x86_64-linux-gnu.so" exists and can find all library dependencies (CUDA, ffmpeg).
On Unix systems, you can use ldd on the file to see whether it can find all dependencies.
On Windows, you can use "dumpbin /dependents" in a Visual Studio command prompt or

Hi @KevinZ-718

Please check out https://github.com/RomanArzumanyan/VALI which is actively developed and maintained VPF spin-off. It has compatible API and module naming. In case your issue reproduces with VALI, just duplicate it there.

Unfortunately there's no active development going in VPF public repo now, so I won't be able to help you here.
