In our TF examples, we use
return_tensors="tf"for the data collators. However,prepare_tf_datasetandto_tf_datasetactually use a NumPy loader internally, which we wrap with atf.data.Datasetat the end. As a result,return_tensors="np"works much better for them, and avoids some weird slowdown bugs we've experienced.This PR replaces every instance in our notebooks with
return_tensors="np", and adds some explanatory text above. (cc @gante, @amyeroberts, @sayakpaul just so you're aware)
