If keepdim is True, the output tensor is of the same size as input except in the dimension dim where it is of size 1. Otherwise, dim is squeezed (see torch.squeeze()), resulting in the output tensor having 1 fewer dimension than input. Parameters. input – the input tensor. dim – the dimension to reduce.

BoolTensor actually uses a byte for each element instead of a bit. To Reproduce. Steps to reproduce the behavior: import torch x = torch.

02.08.2017 · I am seeing this behavior with the conda version of PyTorch. If you do torch.sum((y_hat == y).float()) then it is fine. Sum of a boolean tensor. Lifeng_Jin (Lifeng Jin) August 2, 2017, 3:23pm #1. Is it known that if you do torch.sum(y_hat == y), if the sum is larger than 255, the sum will be whatever - 255? I am seeing this ...

torch.logical_or(input, other, *, out=None) → Tensor. Computes the element-wise logical OR of the given input tensors. Zeros are treated as False and nonzeros are treated as True. Parameters. input ( Tensor) – the input tensor. other ( Tensor) – the tensor to compute OR with. Keyword Arguments. out ( Tensor, optional) – the output tensor.

12.03.2019 · I found a behavior that I could not completely explain in boolean indexing. While it works fine with a tensor >>> a = torch.tensor([[1,2],[3,4]]) >>> a[torch.tensor([[True,False],[False,True]])] tensor([1, 4]) It does not work with a list of booleans >>> a[[[True,False],[False,True]]] tensor([3, 2]) My best guess is that in the second case the bools …
