Description
It is very easy to forget to pass the attention mask, giving bad output.
On the other hand it is very unlikely that someone doesn't want to use
an attention mask. In such cases, it is always possible to create a
custom mask all elements set to
True
.While at it, also consistently make
piece_ids
/attention_mask
positional arguments, while making all other arguments kwarg-only.
