Pytorch: Create an boolean tensor (type: torch.ByteTensor)?

Already found it:

a = torch.zeros(10)
b = a.type(torch.ByteTensor)

Isn't this more economical (albeit longer):

a = torch.zeros(10, dtype=torch.bool)

or, in older versions,

a = torch.zeros(10, dtype=torch.uint8)

(Thanks @drevicko for the pointer to bool.)
