I found the root cause and the workaround.

Fedora 39 uses the new Python 3.12 version by default, but faiss_cpu supported 3.11 only and faiss_cpu wheel (binary install package) is not compatible with 3.12 too, therefore the workaround is to use python 3.11 with virtual environment:

dnf install python3.11
cd ./NeuroGPT
deactivate # in case is if you have activated venv before with python 3.12 support
python3.11 -m venv venv311
source venv311/bin/activate
python --version # check that python version in new virtual environment is the 3.11 and is Not 3.12
pip install faiss-cpu # doublecheck that you can successfully install faiss-cpu now

#you may edit, but I did no check, start_webui_linux.sh to use venv311 or do it like me:
mv ./venv ./venv.old
ln -s ./venv311 ./venv

./start_webui_linux.sh

This workaround is for Fedora 39 that uses latest new Python 3.12 by default and faiss-cpu is not supported 3.12 yet at this moment. When faiss-cpu project will build version compatible with 3.12 we will not needed in this workaround anymore.

I put my troubleshooting and the workaround with all explanation already above.
