[文档]def array_equal(a1, a2):
"""
True if two tensors have the same shape and elements, False otherwise.
Parameters
----------
a1, a2 : array_like
Input arrays.
Returns
-------
b : bool
Returns True if the tensors are equal.
See Also
--------
allclose: Returns True if two tensors are element-wise equal within a
tolerance.
array_equiv: Returns True if input tensors are shape consistent and all
elements equal.
Examples
--------
>>> import mars.tensor as mt
>>> mt.array_equal([1, 2], [1, 2]).execute()
True
>>> mt.array_equal(mt.array([1, 2]), mt.array([1, 2])).execute()
True
>>> mt.array_equal([1, 2], [1, 2, 3]).execute()
False
>>> mt.array_equal([1, 2], [1, 4]).execute()
False
