Hello! guys. Has anyone ever encountered such mistakes? How the errors fix？

The cause of the error is that you don't follow the first step of the "Instructions". If you download the BSDS500 dataset and extract it at the right folder, this error will not happen. Because you have to use the BSDS500 dataset to generate the images of MNISTM.
