order (int): The order or p upon which the norm is calculated.
Valid values include:
None, inf, -inf, 0, 1, -1, 2, -2, ...
axis (int): The axis along which to compute vector norms.
out (GPUTensor): where to write the results to. Must be
of the expected result shape.
Returns:
GPUTensor: p-norm of tsr along the specified axis.
Raises:
IndexError if invalid axis specified
AttributeError if invalid order specified
