[akurniawan]

Hi @monajalal, thanks reporting the issue! It seems that the API has changed from ignite, will try to update it with new API as soon as I can!

[monajalal]

Thanks a lot.

[akurniawan]

Hi @monajalal, happy to tell you that I have fixed the error and now I have updated the requirement to pytorch 0.4 in order to run it. If you still facing the same problem even with pytorch 0.4.0, don't hesitate to let me know, thanks!

[DexterZeng]

Hi @akurniawan, I met the same problem here. I am using pytorch 0.4, but still it reports:

weixin@weixin-All-Series:~/PycharmProjects/csming/pytorch-sentiment-analysis-master$

File "run.py", line 8, in

ImportError: No module named engines

By referring to the documentation, it seems that it might be "ignite.engine" instead of "ignite.engines". Then I met another problem:

Traceback (most recent call last):

Do you know how to fix this one?
Many thanks,
Weixin.

[akurniawan]

Hi @DexterZeng, I can run the code just fine after changing from ignite.engines import Engine to from ignite.engine import Engine. Though, my pytorch version is currently 0.4.1. Can you try to upgrade the version first and let me know if you still facing the same problem? Thanks!

[DexterZeng]

Hi @akurniawan, thank you for your reply.
After I upgraded pytorch to 0.4.1, the previous problem was solved. However, it still reported an error:

WARNING:root:File 'models/sentiment-*.pth' is not found, skip restoring model
ERROR:ignite.engine.engine.Engine:Current run is terminating due to exception: can't convert CUDA tensor to numpy. Use Tensor.cpu() to copy the tensor to host memory first.

Then I changed .numpy() in line 111 and 123 in run.py to .cpu().numpy(), it reported another error:

Then I realized I used my own dataset, which reads like:

5,i like it
2,i hate it
...

Is there something wrong with my dataset or ?
P.S. The link [4] seems to be invaild.

[akurniawan]

Hi @DexterZeng, sorry I just get back to you. I have push the fix for .cpu() in run.py as you reported and also fix the link to the correct dataset.

Regarding your problem, is it possible that your dataset is not correctly formatted? Such as:

1. There exist a , and the field is not quoted by "". For example 5,hi, how are you?. The csv parser will split the line as an array with three contents where there should only be two.
2. This one I'm not really sure but possible, an empty line "". I don't know how the parser behave if your data looks like this

5,i like it
2, i hate it
""
3, i like it

[DexterZeng]

Hi @akurniawan, thank you for your response.
Although I have downloaded your dataset and used it, an error was still raised:

[akurniawan]

Hi @DexterZeng, sorry again for the late reply. Are you using cnn based model? If yes then I suspect there are words that quite short so that even the smallest filter in cnn can't afford travel through it.
