Return the number of dimensions of a tensor.
Parameters
----------
a : array_like
Input tebsir. If it is not already a tensor, a conversion is
attempted.
Returns
-------
number_of_dimensions : int
The number of dimensions in `a`. Scalars are zero-dimensional.

Examples
--------
>>> import mars.tensor as mt
>>> mt.ndim([[1,2,3],[4,5,6]])
2
>>> mt.ndim(mt.array([[1,2,3],[4,5,6]]))
2
>>> mt.ndim(1)
