What are the pre-requisites for scikit-learn?
What are NumPy, SciPy, and matplotlib?
NumPy is a library for Python that adds support for large, multi-dimensional arrays and matrices, along with a vast collection of high-level mathematical functions to operate on these arrays. SciPy is a library that uses NumPy underneath and provides algorithms for optimization, integration, interpolation, eigenvalue problems, etc. Matplotlib is a plotting library for Python that provides complete 2D and 3D plotting features.
