Launching throws error with Exllamav2 stating "Tokenizers" are not found

[Adzeiros]

Followed the install instructions, launching the server.py in exui throws the below error:

  File "G:\_AI\exui\server.py", line 11, in <module>

Workaround is to install the "tokenizers" package which does not seem to be included in the provided requirements.txt. So just do a pip install tokenizers in your venv.

tokenizers isn't included as a requirement because it isn't needed for all models, only the ones that aren't made with SentencePiece or don't include the tokenizer.model SPM file. I guess I could add a check and a more helpful error message.
