Cheers, I’m receiving an error when augmenting masks prior to training a model for semantic segmentation. Consider img as RGB image matrix. Consider mask as a matrix with integer elements from 1 to 11. Code is as follow…

Hi! I am wondering what the fastest dimension ordering for convolution operations on the GPU using CUDNN currently is. Flux uses WHCN (column major), pytorch uses NCHW (row major) which is exactly the same. So to say, t…
