Thank you for releasing the 1.7.3 version!
When running conda install -c pytorch faiss-gpu==1.7.3 inside a Conda environment with Python 3.10, I am getting the following error message:
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:
Specifications:
- faiss-gpu==1.7.3 -> python[version='>=3.7,<3.8.0a0|>=3.8,<3.9.0a0|>=3.9,<3.10.0a0']
Your python: python=3.10
If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.
I hope not to need to downgrade to Python 3.9, because 3.10 is already >1 year old.
Is there a chance that faiss-gpu 1.7.3 will be supported on python 3.10?

Pre-packaging with another version of python is not currently in our priorities.
If you need 3.10, I'd recommend compiling yourself, see
FYI for anyone compiling themselves for python 3.10, on Ubuntu 22.04 I had to add -DBLA_VENDOR=Intel10_64_dyn to the cmake commandline in order to get proper linking with MKL.
We just released 1.7.4 and it supports python 3.10 🥳 @urialon
Great, thanks a lot!
