TypeError: 'generator' object is not callable

Python 2.7
torch 1.0.1
torch text 0.4.0

I try to preprocess the data, but when it save data, a TypeError occurs: 'generator' object is not callable. Can anyone help me?

Traceback (most recent call last):

I change knl_seq_length_trunc to 200, and get the same error

Please use python>=3.6.

Thanks. I change python to 3.6.5, and I meet with another error:ValueError: max() arg is an empty sequence

OK。
added this modify to the inputter.py and it workes.
if len(b) == 0: continue
