[Python] Fixing Hugging Face Login Issue (504 Gateway Timeout & Invalid Token Error)

Issue I was trying to log in to Hugging Face CLI, but I kept getting the following error:

requests.exceptions.HTTPError: 504 Server Error: Gateway Time-out for url: https://huggingface.co/api/whoami-v2

Even after trying multiple fixes, the error persisted and eventually changed to:

requests.exceptions.HTTPError: Invalid user token.

What I Tried (But Didn’t Work)

Logging in again using huggingface-cli login → Failed Upgrading Hugging Face Hub (pip install --upgrade huggingface_hub) → No effect Clearing cache & re-installing dependencies → Still the same error

Final Solution That Worked After many attempts, the issue got fixed by setting up a virtual environment and reinstalling everything from scratch.

Here’s what worked:

python -m venv hf_env source hf_env/bin/activate # (Windows users: hf_env\Scripts\activate) pip install huggingface_hub huggingface-cli login

Why This Works? A virtual environment creates an isolated Python environment, avoiding conflicts with existing dependencies. If there’s an issue with your global Python installation, this helps bypass it. It ensures a clean install of huggingface_hub without any corrupted files.

If you’re facing similar issues, try this approach and let me know if it works for you!
