Thank you for the notes on this issue. Unfortunately, I haven't tested with Windows and it looks like one of the packages referenced, faiss-gpu, doesn't support Windows.

If you're willing to give it a try, there is a port of faiss for Windows here: https://github.com/bitsun/faiss/blob/master/INSTALL_cmake.md. Otherwise, I'll work to locate a Windows machine to further test the install process on Windows.

The thought would be to build this package and ignore the faiss-gpu dependency when installing txtai.

@davidmezzetti I tried it, appears setting up faiss on windows is not that straightforward. I have a box with big GPU and Windows OS, can't move to linux as of now. Will try to find a linux box for experimentation, meanwhile please let us know if you find any work around!

After spending a good deal of time working to setup an environment to compile faiss on Windows, I realize that it's not a practical solution. Will investigate having a fallback option for Windows when faiss isn't present.

@davidmezzetti thanks for update, highly appreciate this!

This issue has been resolved with v1.1.0, Windows installs should now work without issue.
