torch.meshgrid raises RuntimeError if no arrays are passed

[Nin17]

If no arrays are passed to torch.meshgrid a RuntimeError is raised whereas numpy returns an empty tuple.

import torch
torch.meshgrid()

raises:

RuntimeError: meshgrid expects a non-empty TensorList

Whereas with numpy:

import numpy as np
np.meshgrid()

returns:

()

I believe the numpy implementation is the correct output given the wording ("tuple of N arrays, where N is the number of provided one-dimensional input arrays") of the docstring for meshgrid.
