question about the version of pytorch

Hi,

Thanks for your kind sharing.
I want to reproduce your results on my device, but my training results are too bad,
The evaluating HR and NDCG of some epochs are 0.0000, do you have any idea about this case? And could you tell me the Pytorch version that you use in your side?

Thanks.

Could you share your training curve? I tested the repo using pytorch 0.2 but I guess it should work under 0.3 and 0.4 as well.

@LaceyChen17 @zhiqiangzhongddu , I got the same issue, see the curves on dataset ml-1m,

Before, I used Pytorch 1.0.1, the latest version.
I tried Pytorch 0.4.0 with Cuda 80&90, but they don't work.
Error:
RuntimeError: input and target shapes do not match: input [1024 x 1], target [1024].

And I'm not success to install Pytorch 0.2 and 0.3 on my computer. It seems Conda doesn't support them anymore.

I reproduced the bug in pytorch 1.0 as well. I am working on it now. Yihong

news: the same bug exists with Pytorch-0.3.1, Cuda=90&80&100 in my computer.

@zhiqiangzhongddu @GabbyHE

The bug was mainly caused by MSELoss.

The repo works well under the latest pytorch(1.0.1post2) now.

Thank you for reporting the bug. Also, pay attention to l2_regularization parameter.

Strong l2_regularization might lead to model underfitting and thus HR 0 & NDCG 0.
