def deg2rad(x, out=None, where=None, **kwargs):
"""
Convert angles from degrees to radians.
Parameters
----------
x : array_like
Angles in degrees.
out : Tensor, None, or tuple of Tensor and None, optional
A location into which the result is stored. If provided, it must have
a shape that the inputs broadcast to. If not provided or `None`,
a freshly-allocated tensor is returned. A tuple (possible only as a
keyword argument) must have length equal to the number of outputs.
where : array_like, optional
Values of True indicate to calculate the ufunc at that position, values
of False indicate to leave the value in the output alone.
**kwargs
Returns
-------
y : Tensor
The corresponding angle in radians.
See Also
--------
rad2deg : Convert angles from radians to degrees.
unwrap : Remove large jumps in angle by wrapping.
Notes
-----
``deg2rad(x)`` is ``x * pi / 180``.
Examples
--------
>>> import mars.tensor as mt
>>> mt.deg2rad(180).execute()
