You have a GPU available, but only `faiss-cpu` is currently installed. about ragatouille

Hey, there seems to be an issue with the attribute that we use as a proxy to check whether faiss has GPU bindings or not. This should be purely an annoyance with no actual impact (i.e. the GPU will be used in spite of the message). I'll update this in the next fix release, thank you!

For me, it is more than annoyance since the embedding/index process does not use GPU.

Oh, this is particularly odd then, as the use of faiss in RAGatouille is limited to checking if it has a GPU-related attribute, and the rest is handled upstream 🤔. Could you run pip-freeze to make sure there's no conflicting faiss versions? (It's happened to me before where both faiss-gpu and faiss-cpu were present, and caused some conflicts).

If there's no conflict, it'd be really helpful if you could get your env details (OS, Python version, CUDA version, GPU used, pip freeze) and create an issue on https://github.com/stanford-futuredata/ColBERT about the GPU not being used! Thanks a lot and sorry about the issue.
