DownloadAndLoadHyVideoTextEncoder No package metadata was found for bitsandbytes

[Bas667]

The following problem: When I start the workflow, I get the following error message:

DownloadAndLoadHyVideoTextEncoder No package metadata was found for bitsandbytes

The download should actually start automatically. I then manually downloaded the folder “llava-llama-3-8b-text-encoder-tokenizer” from huggingface and packed it in /models/LLM/. But that doesn't help either.

Here is the complete log:

During handling of the above exception, another exception occurred:

The bnb_nf4 quantization option requires bitsandbytes library installed, I didn't want to make that automatic as that package sometimes has issues and is preferable to be installed manually.

For portable that can be done by running this command in the ComfyUI_windows_portable\python_embeded -folder:

python.exe -m pip install bitsandbytes

Not working for me it says SyntaxError: invalid syntax

You have to use:
./python.exe -m pip install bitsandbytes
