Sklearn Source installation under Windows

Brief introduction

Under Windows compile Sklearn source code, the main note two points:

2. Compilation order

Building a compilation environment

If the environment is not well built, the most common error is "error:unable to find Vcvarsall.bat"

In Python 3.5, for example, when VisualStudio is installed by default, Python tools is not typically selected, so reinstall VisualStudio, select Custom, and tick the following options.

Compilation order

1. Compiling Sklearn source code

Python setup.py build_ext-i

1. Install Sklearn Source code

Python setup.py Install

Be sure to use the Build_ext command, if you start with install, that's okay, use Build_ext again, and finally use install.
