Torch tensor set the negative numbers to zero

Question

x=torch.Tensor({1,-1,3,-8})

How to convert x such that all the negative values in x are replaced with zero without using a loop such that the tensor must look like

th>x 1 0 3 0

Answer 1

Pytorch supports indexing by operators

a = torch.Tensor([1,0,-1])
a[a < 0] = 0
a

tensor([1., 0., 0.])
