when i try to train this model on double GPUs, an error occurred, suggesting that in models.maniqa.py in line 117 x = torch.cat((x6, x7, x8, x9), dim=2) appeared some data in CUDA0, some data in cuda1, please ask how this problem should be solved? I don't see some suitable solution on the internet.

Hi, I know this question.
This reason is the problem of implementation. It just support one GPU to training.

One solution is to return the output of each layer directly, without using the SaveOut module
