I have a tensor 100 x 50 x 60, and I have a mask acting on images  50 x 60 and selects some 1000 pixels of interst (out of 30,000 in that image).
When I apply the mask to the tensor mentioned in the beginning, it throws an error and doesn’t broadcast to the 100 images. I want an output like this : 100 x 1000 i.e. the mask applied to 100 images (batch size).
If there’s no way to broadcast mask in Pytorch, how can I do it manually?
