There seems to be something wrong with your model code？

[Yucioiooo]

Your model code seems to have a dimension mismatch.

Our code is based on Python version 3.7 and Pytorch version 1.7.1, same as that of LibCity. If you are using another version of Pytorch you may get this kind of issue.

这个似乎和环境没有关系，我遇到了一样的问题，把HIEST的line 256的self.filter_convs.append(nn.Conv2d(in_channels=self.residual_channels, out_channels=self.dilation_channels, kernel_size=(1, self.kernel_size), dilation=new_dilation))中的Conv2d改成Conv1d似乎能解决这个问题，不知道是否可以这样解决？

The results after modification seem to be far from the paper.

I also don't think it's the experimental environment

How to explain the different running results? Or can you upload your running results?

我也不认为这是实验环境

如何解释不同的运行结果？或者你能上传你的跑步结果吗？

我从2d改成1d似乎还是不能解决这个问题。我没有成功跑通过这个程序

It looks like you got a different Pytorch version. The environment does matter. Please also check the section about setting environment of our doc You can have a try on GWNet and I think you will get the same error message. I have tried libcity code with Pytorch1.9 before and got the same error message.

When I used torch1.7.1, it prompted me that the GPU was unavailable. Due to this compatibility issue, I modified the torch version to run, but I don’t think it was a version problem.

What is the CPU model and CUDA version you are using?
