【PYTORCH】RuntimeError: torch. cuda. FloatTensor is not enabled.

The reason for this error is that you are installing cpu Version of pytorch Up operation GPU Version of pytorch Code for .

resolvent ：

Place the error in ".cuda()" Switch to ".cpu()"

Some of the downloaded code needs GPU Calculation , And computers don't GPU, At this point, you can add the following code at the beginning of the code to obtain whether the current computer has GPU
# gpu or not
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")

And then in the code use .to(device) Replace .cuda() perhaps .cpu() Can be found in GPU On your computer GPU Computational acceleration , In the absence of GPU On your computer CPU Calculation , But it's slower
