Invalid credentials in Authorization header - HfApiModel

Course
1

Dear Team,

I am currently enrolled in the Agents course and encountered an error while attempting to run the Smol_Agents notebook. Specifically, I received an error when using model=HfApiModel() with my free Hugging Face API key.

Could you please assist me in resolving this issue?

The above exception was the direct cause of the following exception:

The following basic measures may help, but the Inference API is currently unstable and Qwen 2.5 Coder 32B is busy, so there is also the possibility of individual problems…
I’ll bring it if I find something.

Can you confirm if accessing Inference API requires Pro subscription or Free token will work?

I can’t try the Free token at the moment…

The same problem was reported quite a lot in the agents course channel on HF Discord. It would be easier if the following method was still available…

from Discord:

You can use https://pflgm2locj2t89co.us-east-1.aws.endpoints.huggingface.cloud/ as model_id (Qwen 2.5 Coder 32B)
