torch.isposinf# torch.isposinf(input, *, out=None) → Tensor# Tests if each element of input is positive infinity or not. Parameters input (Tensor) – the input tensor. Keyword Arguments out (Tensor, optional) – the output tensor. Example: >>> a = torch.tensor([-float('inf'), float('inf'), 1.2]) >>> torch.isposinf(a) tensor([False, True, False])
