Original GitHub issue: https://github.com/SillyTavern/SillyTavern-Extras/issues/80

I receive the following error after running pip install -r requirements-complete.txt followed by python server.py --enable-modules=caption,summarize,classify,chromadb. Currently running python 3.10.

I've tried deleting the virtual environment and pulling a fresh repo but issue still persists. Only happens when trying to use the classify or chromadb modules.

Looks like a corrupt model. Try cleaning the HF hub downloads cache and redownload it. Usually in your user profile directory, .cache/huggingface/hub

Thanks! Yes I managed to resolve the issue by deleting the chroma, huggingface and torch directories in .cache. Then rerunning python server.py --enable-modules=caption,summarize,classify,chromadb
