torch.pow is inconsistent #26495
Description
import torch
empty = torch.randn([0])
tensor = torch.randn(2, 3)
result = torch.pow(tensor, 1, out=empty.clone())
RuntimeError: The size of tensor a (0) must match the size of tensor b (3) at non-singleton dimension 1
However, the following works:
import torch
empty = torch.randn([0])
tensor = torch.randn(2, 3)
result = torch.pow(tensor, 0, out=empty.clone())
