[Derjyn]

As a potential fix, I hopped into a virtual environment for my SDWUI set up, and did a pip install of the sentence_transformer library. The above traceback/error has gone away, but I don't see any hint of Incantations being active - that is, no options, feedback in the console, etc.

[v0xie]

Sorry about that. Try pip install "sentence_transformers>=2.2.2" "transformers==4.30.2"

[v0xie]

We're not using sentence transformers in the main branch so this is not an issue for the time being.
