Original GitHub issue: https://github.com/RVC-Project/Retrieval-based-Voice-Conversion-WebUI/issues/1545

Today tried to set up RVC beta and after installing all libraries like - "pip install torch torchvision torchaudio", "pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu117" and pip install faiss-gpu. And when launching the neural network and typing "python infer-web.py", I get the following error: File "C:\Rvc\Retrieval-based-Voice-Conversion-WebUI-updated0618v2\infer-web.py", line 20, in
import faiss
ModuleNotFoundError: No module named 'faiss'.

What can I do to fix this problem?

Please check once with pip list to make sure it is really installed and that the virtual environment is correct
