WebApr 16, 2024 · The pseudo-code is shown as follow (it can not work in pytorch): x = torch.rand ( (3,1,6,6), requires_grad=True) # [batch_size, channel, w, h] left_index = torch.randint (0,4, (3,)) right_index = left_index + 2 bottom_index = torch.randint (0,4, (3,)) top_index = bottom_index + 2 new_x = x [:,:,left_index:right_index, bottom_index:top_index] Web1 day ago · Is there any way to do it all at once in pytorch? It seems that x [:, :, masks] doesn't work since masks is a list of masks. Note, each mask has a different number of True entries, so simply slicing out the relevant elements from x and averaging is difficult since it results in a nested/ragged tensor.
