RuntimeError: derivative for aten::linear_backward is not implemented on MPS

autograd
1

Dear all,

I’m currently using Pytorch 1.13.1 on my Macbook M1 Pro

Long story short, I wanted to reproduce this notebook:
PINN/solve_PDE_NN.ipynb at main · nanditadoloi/PINN · GitHub on my machine. But obviously, I have to change the device to "mps"

However, it returns RuntimeError: derivative for aten::linear_backward is not implemented if I set device = torch.device("mps")

But it runs fine if I set the device to "cpu". Does anyone have a similar problem?

Addition: Just found the culprit. In the training step in the given link, it combines two loss functions the mse_u and mse_f. I tried to use mse_u only and it works fine on MPS, but when I tried mse_f only, the error message appear.

But I still have no idea why.

Thank you in advance
