Numpy, SciPy, MatPlotLib installation and configuration in Python

After installing Numpy, SciPy and MatplotLib, Python can become a very sharp scientific research tool. I searched many installation tutorials before I found the correct resources to configure and share.

    Installation environment: 64-bit python2.7

    Download the exe of the three libraries in http://pan.baidu.com/s/1c1Phqko, because the use of MatplotLib requires the support of Numpy, so first click to install Numpy, then Scipy, and finally MatplotLib, click next all the way .

     If the error message that Python 2.7 was not found in the registry appears during installation, create a new register.py, copy the following code to run, and output: Python 2.7 is already registered means the problem has been solved.
