NumPy’s array class is called ndarray. It is also known by the alias array. Note that numpy.arrayis not the same as the Standard Python Library class array.array, which only handles one-dimensional arrays and offers less functionality. The more important attributes of an ndarrayobject are: ndarray.ndim the number of axes (dimensions) of the ...

NumPy operations return views or copies. Views share the underlying storage of the original array. Changing the values of a view will change the original and vice versa. Read the documentation to determine if an operation returns a copy or a view. Most operations return a view when possible and a copy otherwise.

Return values. Numpy functions return either views or copies. Views share data with the original array, like references in Java/C++. Altering entries of a view, changes the same entries in the original. The numpy documentation says which functions return views or copies. Np.copy, np.view make explicit copies and views.

numpy.ndarray is that the content is allocated on the GPU memory. Most of the CuPy array manipulations are similar to NumPy. Take the Euclidean norm (a.k.a L2 norm) for example – NumPy uses numpy.linalg.norm to calculate it on CPU. 1 >>> x_cpu = np.array([1, 2, 3]) 2 >>> l2_cpu = np.linalg.norm(x_cpu) We can calculate it on a GPU with CuPy with:

NumPy Fundamentals • Why Numpy? • Remember that Python does not limit lists to just elements of a single class • If we have a large list and we want to add a number to all of the elements, then Python will asks for each element: • What is the type of the element • Does the type support the + operation • Look up the code for the + and execute • This is slow

• NumPy arrays have a fixed size at creation, unlike Python lists (which can grow dynamically). Changing the size of an ndarray will create a new array and delete the original. • The elements in a NumPy array are all required to be of the same data type, and thus will be the same size in memory.
