when run the train.py
ModuleNotFoundError: No module named ‘onmt.IO’ has happened, how to deal with it?

The traceback is as follow:
Traceback (most recent call last):
File “D:/PyCharm/WorkSpace/OpenNMT-py-master/train.py”, line 502, in

I also get this error when running on google colabratory:

using pytorch 0.4.0 and torchtext 0.3.0

According to the github project:

onmt.IO was refactored into a onmt.io package recently.
This indicates that your preprocessed dataset is too old.

I solved this problem by retraining my dataset, i.e. to preprocess again.

Hope this help.
