mars.tensor.exp2(x, out=None, where=None, **kwargs)[source]

Calculate 2**p for all p in the input tensor.

x : array_like
Input values.
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.


out : Tensor
Element-wise 2 to the power x.
