NumPy, SciPy and Python Image Library

Two related third-party packages named NumPy and SciPy [3] provide tools for creating arrays (vectors, matrices, and tensors) and a plethora of tools for manipulating these arrays. These tools provide very efficient codes that make programming easier and computations quick. Since neural models consider arrays of neurons these tools are essential. A third package named Python Image Library (PIL) provides tools or reading and writing image data.
