this error happened while I was training and I know nothing about this. Help me on this :))
Looks like you are using HuggingFace’s WandbCallback() API. A huggingface
Trainer expects a list of Callbacks, not an individual callback.
Seeing the error message, simply wrapping the
WandbCallback() in brackets as
[WandbCallback()] should fix the error.
I hope you were able to successfully resolve the issue. If you have any other questions, please do not hesitate to reach out.
