When i just run train.py,something was wrong

[Zengpeizhi]

@whywhs hello,could you please to help me to solve the problem?(i just follow you readme and when i run Train.py ,it was wrong)

[whywhs]

Of course. I just ran my program on computer but there was no error, so I am not sure what caused your problems. Could you please show me the complete error message? Or just show me where the error occurred in my program.

Thank you very much for your reply! The code error information is shown in the attachment.I just follow your instruction and run gen_pkl.py,and it work.But after I run Train.py,the mistake happen.

I see your pictures, but I can't see where the error occurred in my program. So, maybe you can take a complete screenshot of the error. Is your pytorch version 0.3?

oh，sorry,my pytorch is 1.0.1 .So the error was because of that?If so,I try to use 0.3

[whywhs]

yes! I've been finished this project about 1 year ago, so the pytorch version is 0.3

@whywhs Thank you very much!When I use pytorch0.3,it runs!

Furthermore, you can write num_works in Train.py (line 128, line 135) if you want because this can make your training faster than before.

hello，thank you very much for your help! And if i want to improve the result ,what do you think i should do?Can you give me some advice?

[whywhs]

Sure. I think you can get a better result if you can do these:

1. When you finished your training, you can fix the weight of the encoder and train the decoder separately, this will improve your result about 3-4%.
2. If you want a better result, the batch_size is important. Meanwhile, you can also get a faster speed.
3. The teacher-forcing ratio is also important, you can try some higher ratio if you are interested.
