Solving Invalid credentials in Authorization header error when downloading models from Hugging Face

  • This happens when your Hugging Face token is not anymore authorized for any reason

  • In this case run below command and delete your system registered token

  • Open a CMD and type below and hit enter

  • huggingface-cli logout

  • This will fix the below error

  • You may also get error when trying to download gated models, that time you have to enter your access token to your system and approve that model

  • But I don't put any Gated models into any of my installer so that is not an issue with my installers (i put them into public repos)

  • Or I provide a valid token with the installer itself so you don't have to do anything
