Fastai2 sometimes no metrics output for text_classifier_learner

I’m following the github example for NLP somewhat closely on some data of my own.

I am sometimes not getting any output for fit_one_cycle or fine_tune.

learn = text_classifier_learner(dls_clas, AWD_LSTM, drop_mult=0.5, metrics=[accuracy, F1Score]).to_fp16() learn = learn.load_encoder('enc1') learn.fit_one_cycle(10, 2e-2)

The progress bars always show, but the results with epoch, metrics, time, etc sometimes do not show up. The progress bars disappear but no results ever come up.

I am running in JupyterNotebook on Google Cloud Platform.
