train error: svd_cuda

[vkl-git]

Hello, thank you for your work.When I tried to train with my own datasets, I used the SRFlow_DF2K_4x model, but during the training process, "svd_cuda: the updating process of SBDSDC did not converage (error:11)" error appeared.Have you ever encountered the same reason in your training?Is there a solution?

which cuda and pytorch version?

[vkl-git]

Thank you for your response.  I used CUDA 10. 0 and pytorch1.7. Are there any problems?

I train it with same problem before, But I run setup file all problem are display.
If GPU is 3090,cuda version should be cuda 11.0

Hi viki-li, this error usually occurs in the back propagation step of the 1x1 convolution, when the learning rate is too high.

Does it help to reduce the learning rate?
