TypeError: __new__() missing 1 required positional argument: 'attention_state'

[zhyb]

when I run 'python3 aster/demo.py'.Errors occurred as follows :

TypeError: in converted code:

/home/zyb/aster/core/sync_attention_wrapper.py:78 call
    alignment_history=self._item_or_tuple(all_histories))

TypeError: __new__() missing 1 required positional argument: 'attention_state'

I did face the exact same issue, the problem is in the _compute_attention() function in line: 52

As is evident from the tensorflow source code the function returns three things :

attention, alignments, next_attention_state

The attention_state has not been accounted for when calling the function and therefore the missing value is actually this next_attention_state that has not been passed on to the AttentionWrapper. I have created a pull request for the same, which is accessible here.
