Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`:
|
| 866 |
-
|

position_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):

Contains pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention

| 895 |
-
blocks) that can be used (see `past_key_values` input) to speed up sequential decoding.
|
| 896 |
-
|
| 897 |
-
If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that

don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of all

-
Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
|
| 902 |
-
is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
|

-
model's internal embedding lookup matrix.

-
use_cache (`bool`, *optional*):

`past_key_values`).
