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)CometCallback
CometCallback (project_name, log_model_weights=True)
