How to use?

Key is to create the callback CometMLCallback before you create Learner() like this:

from fastai.callback.comet import CometMLCallback

comet_ml_callback = CometCallback('PROJECT_NAME')  # specify project

learn = Learner(dls, model,
                cbs=comet_ml_callback
                )

learn.fit_one_cycle(1)

class CometCallback[source]

CometCallback(project_name, log_model_weights=True) :: Callback

Log losses, metrics, model weights, model architecture summary to neptune
