:class:`cupy.ndarray` is designed to be interchangeable with :class:`numpy.ndarray` in terms of code compatibility as much as possible.
But occasionally, you will need to know whether the arrays you're handling are :class:`cupy.ndarray` or :class:`numpy.ndarray`.
-One example is when invoking module-level functions such as :meth:`cupy.sum` or :meth:`numpy.sum`.
-In such situations, :meth:`cupy.get_array_module` can be used.

:class:`cupy.ndarray` and :class:`numpy.ndarray` are not implicitly convertible to each other.
That means, NumPy functions cannot take :class:`cupy.ndarray`\s as inputs, and vice versa.
-- To convert :class:`numpy.ndarray` to :class:`cupy.ndarray`, use :meth:`cupy.array` or :meth:`cupy.asarray`.
-- To convert :class:`cupy.ndarray` to :class:`numpy.ndarray`, use :meth:`cupy.asnumpy` or :meth:`cupy.ndarray.get`.

+- To convert :class:`cupy.ndarray` to :class:`numpy.ndarray`, use :func:`cupy.asnumpy` or :meth:`cupy.ndarray.get`.
Note that converting between :class:`cupy.ndarray` and :class:`numpy.ndarray` incurs data transfer between
the host (CPU) device and the GPU device, which is costly in terms of performance.
