Save predictions on test data if test is enabled

Hi SciBERT team, First of all, it is an awesome work. I have a question cum feature request.

Q1.
Is scibert predicting the entity for each token or for a sentence (bunch of tokens) from the test set?

Q2. Is the accuracy/f1 score calculated at the "span label" level (PER) or "IOB label + span label" level (B-PER)?

If we have a feature to save the predictions (in addition to outputting just the acc/f1 score) on the test data when if the test is enabled during training, we can figure out the above such questions ourselves.

Thank you
