[hh23333]

Hi, i had a problem in training. when load source and target data simultaneously, everything was normal at begining few epoch, but after that, it appears that it can't keep on loading data, and I must restart the program. Have you met this problem? What can I do to solve it? Thanks

I did not meet this problem before. I have no idea myself without debugging in your case.
