… cross-attentions when requested In class BertEncoder.forward() method, `all_cross_attentions` is defined in Line 409, but not maintained, which causes a retuning of None object when requested. In this revision, `all_cross_attentions` is properly updated and maintained in Line 461. The maintenance code is referred from the original Hugging-face Transformer library https://github.com/huggingface/transformers/blob/v4.15.0/src/transformers/models/bert/modeling_bert.py Line600, and is tested to be valid.
