torch.logical_and — PyTorch 2.5 documentation (original) (raw)

torch.logical_and(input, other, *, out=None) → Tensor¶

Computes the element-wise logical AND 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 AND with

Keyword Arguments

out (Tensor, optional) – the output tensor.

Example:

torch.logical_and(torch.tensor([True, False, True]), torch.tensor([True, False, False])) tensor([ True, False, False]) a = torch.tensor([0, 1, 10, 0], dtype=torch.int8) b = torch.tensor([4, 0, 1, 0], dtype=torch.int8) torch.logical_and(a, b) tensor([False, False, True, False]) torch.logical_and(a.double(), b.double()) tensor([False, False, True, False]) torch.logical_and(a.double(), b) tensor([False, False, True, False]) torch.logical_and(a, b, out=torch.empty(4, dtype=torch.bool)) tensor([False, False, True, False])
