[Prepare perceptual data] RuntimeError: cuDNN error: CUDNN_STATUS_NOT_SUPPORTED

[zhhezhhe]

Thans for your great work! When dataroot_LQ has only one image, the code runs OK! But when I put more images (DIV2K dataset) to the dir of dataroot_LQ: /DIV2K/DIV2K_train_HR, the error occurs.

The error occurs when I test Flickr2K/Flickr2K/000001.png. Its size is 2040*1356. When I test another image with a smaller size (some size like 680 * 680), the code runs OK.
