         a new shape compatible with the original shape. One shape dimension is allowed to be ``-1``. When a shape dimension is ``-1``, the corresponding output array shape dimension must be inferred from the length of the array and the remaining dimensions.

+        boolean indicating whether or not to copy the input array. If ``True``, the function must always copy. If ``False``, the function must never copy and must raise a ``ValueError`` in case a copy would be necessary. If ``None``, the function must reuse existing memory buffer if possible and copy otherwise. Default: ``None``.
