Installation troubles on Ubuntu 20.04.3 LTS

[AlexanderNevarko]

Summary

I have tried installing FAISS package according to the installation manual with commands "conda install -c pytorch faiss-cpu", "conda install -c pytorch faiss-gpu", "conda install -c pytorch faiss-gpu cudatoolkit=11.4". After that importing faiss gives me "ModuleNotFoundError: No module named 'faiss'".

Command "conda list" shows me a list of packages with the only faiss-like package in the list: faiss-proc 1.0.0 cuda rapidsai

I am using base conda environment. Don't know how to deal with the problem.

Platform

Ubuntu 20.04.3 LTS NVIDIA GTX 1080 Ti CUDA 11.4 conda 4.11.0

Running on:

• [x] CPU
• [x] GPU

Interface:

• [ ] C++
• [x] Python

Could you try with cudatoolkit=11.3?

Also, which version of Python are you using?

Same problem occurs. During the installation process it writes about package conflicts, but in the end it prints: "Your installed version is: 2.31"

• It is mentioned here that we should install either, not both. Can you check that out?
• Is it possible that you have a file named faiss.py in the same working directory? If yes, that might cause the problem with importing faiss.
• Does creating a new conda environment and installing faiss there fix your issue?

Just my 2 cents.
