1.pycharm Activation Code: http://idea.liyang.io/
(2017/9)
2.matplotlib (Graphics library) installation: see
/*http://blog.csdn.net/u012562681/article/details/77193871
① Installation Address: http://www.lfd.uci.edu/~gohlke/pythonlibs/
② appears fatal error in launcher:unable to create process using ' "'
Problem Solving Method:
Add the display installation before PIP installation; Python-m Easy_install
Specific command: >python-m easy_install numpy-1.13.1+mkl-cp36-cp36m-win_amd64.whl*/
Free Pit declaration: ① download EXE files as far as possible
②python-m pip install numpy This command at the command line to install successfully (install NumPy first, then install the graphics library because of dependencies between each other) (when you follow the first connection installation, you encounter a problem where numpy cannot be installed successfully. Finding this method is easy to solve (python3.6.2)) suggests using this approach directly. Installation Success Tip: Installing collected packages:numpy
Successfully installed numpy-1.13.1

3. Environment variable configuration: 3. X and Pycharm installation will be configured in a good environment, such as error environment variables to find Python's scripts path, and pycharm python.exe file path;
Note the last addition \

4. Detect whether the installation is good:
Enter the import numpy in the Python interpreter without an error
In addition to the drawing validator will appear in the line interface

>>> import matplotlib >>> from matplotlib import Pyplot >>> Pyplot.plot ([1, 2, 3, 4], [1, 2, 3, 4]) [<matplotlib.lines.line2d object at 0x0476c370>] >>> pyplot.show () /pre>
