WebThe gumbel_softmax_sample function adds the Gumbel noise to the logits, applies the temperature and the softmax function. In the gumbel_softmax function we also add evaluation code which simply returns a sample (unrelaxed) from the categorical distribution parameterized by logits. [3]: WebThe easiest way I can think of to make you understand is: say you are given a tensor of shape (s1, s2, s3, s4) and as you mentioned you want to have the sum of all the entries along the last axis to be 1.. sum = torch.sum(input, dim = 3) # input is of shape (s1, s2, s3, s4)
