same problem on MPS M4 Max
While as I using Nvidia GPU cards on Ubuntu (VMs), the blocker became the error in training process, let alone generate index file...

I have the same problem!
Installed on Linux Mint via UV. I'm using a 2080ti. One-Click Training fails. No output after preprocess is done.
Manually training seems to run, but training the index fails. No output in Terminal, no output in the WebUI.
After all, I have a G and D *.pth but no index!

I think i have a solution found that worked for me!
I changed matplotlib and gradio.

python -m pip install matplotlib==3.7.0
and
python -m pip install gradio==3.48.0
(inside of my (venv) seems to work.
Training is ongoing, but there are no errors so far and training uses way more time. (it was unrealistic fast before).
Maybe it could help you too!?

you can run "train feature index" on its own after training to make the .index. also see the gradio 3.48 / matplotlib 3.7 fix earlier in this thread.
