zeros(), zeros_like(), ones() and ones_like() in PyTorch

zeros() can create a 1D or more D tensor filled with zero or more 0., 0, 0.+0.j or False as shown below:

*Memos:

• 
  zeros() can be used only from torch but not from a tensor.


• The default type is float32.
  

import torch

torch.zeros(0)
torch.zeros((0,))
# tensor([])

torch.zeros(3)
torch.zeros((3,))
# tensor([0., 0., 0.])

torch.zeros(3, 2)
torch.zeros((3, 2))
# tensor([[0., 0.], [0., 0.], [0., 0.]])

torch.zeros(3, 2, 4)
torch.zeros((3, 2, 4))
# tensor([[[0., 0., 0., 0.], [0., 0., 0., 0.]],
#         [[0., …
