This error occurred while running torch

The error content probably means that the input type is CPU (torch. Floattensor), and the parameter type is GPU (torch. CUDA. Floattensor)
links to data types: Official links

First of all, please check whether CUDA is used correctly

We usually specify CUDA as follows:

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
inputs.to(device)

In this way, input is converted into CUDA type

The correct way is to:

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
inputs = inputs.to(device)

Reason:
tensor. To() is used to generate a new tensor without changing the original data

However, note that
module. To() is an “in place” method, while the tensor. To() function is not
