Argmax dim 1 keepdim true

WebThe input is assumed to be a channel-first PyTorch Tensor: 1) For not OneHot format data, the values correspond to expected labels, 0 will be treated as background and the over-segment pixels will be set to 0. 2) For OneHot format data, the values should be 0, 1 on each labels, the over-segment pixels will be set to 0 in its channel. Webtorch. mean (input, dim, keepdim = False, *, dtype = None, out = None) → Tensor Returns the mean value of each row of the input tensor in the given dimension dim.If dim is a list of dimensions, reduce over all of them.. If keepdim is True, the output tensor is of the same size as input except in the dimension(s) dim where it is of size 1. Otherwise, dim is …
