先添加pip的环境变量(也在Scripts下面),再用pip安装numpy——在cmd输入如下路径,pip安装numpy:

pip3.6 install C:\Users\lenovo\AppData\Local\Programs\Python\Python36-32\Scripts\numpy-1.13.3-2-cp36-none-win32.whl

C:\Users\lenovo\AppData\Local\Programs\Python\Python36-32\Scripts;

C:\Users\lenovo\AppData\Local\Programs\Python\Python36-32;

C:\ProgramData\Oracle\Java\javapath;

C:\Program Files (x86)\Lenovo\FusionEngine;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;

C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;

C:\Program Files (x86)\Lenovo\Lenovo Home\;

C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\;

C:\Program Files\Microsoft SQL Server\110\Tools\Binn\

20171204用pip安装scipyhe/matplotlib/sklearn,方法和pip安装numpy相同。

进入 www.lfd.uci.edu/%7Egohlke/pythonlibs/ 这个python库下载界面

找到numpy+mkl和scipy下载相应版本

下载完毕后,进入有whl文件的界面,在ftp地址栏输入cmd

再输入 pip3 install +whl文件的全名,安装whl。

    先安装numpy,再安装scipy

scipy下载路径:https://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy 

【安装scipy前,提示先安装Numpy;  Numpy和我之前安装的名称不同,下载路径:https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy】

Scikit-learn下载路径:https://www.lfd.uci.edu/~gohlke/pythonlibs/#scikit-learn

以下参考文档:

https://www.cnblogs.com/rucwxb/p/7297733.html

在命令界面cmd,查看系统版本的方法:

>>> import pip

>>> print(pip.pep425tags.get_supported())

[('cp36', 'cp36m', 'win32'), ('cp36', 'none', 'win32'), ('py3', 'none', 'win32')

, ('cp36', 'none', 'any'), ('cp3', 'none', 'any'), ('py36', 'none', 'any'), ('py

3', 'none', 'any'), ('py35', 'none', 'any'), ('py34', 'none', 'any'), ('py33', '

none', 'any'), ('py32', 'none', 'any'), ('py31', 'none', 'any'), ('py30', 'none'

, 'any')]

>>>

【我没有安装wheel。】

1.1,重新安装numpy【尽管电脑中已经安装过numpy-1.13.3-2-cp36-none-win32,但仍旧要重新下载(主要是mkl)】

pip3.6 install C:\Users\lenovo\AppData\Local\Programs\Python\Python36-32\Scripts\numpy-1.13.3+mkl-cp36-cp36m-win32.whl

1.2,验证:输入随机矩阵;

from numpy import *

random.rand(3,3)

2.1,安装scipy

pip3.6 install C:\Users\lenovo\AppData\Local\Programs\Python\Python36-32\Scripts\scipy-1.0.0-cp36-cp36m-win32.whl

2.2,再次进入python,引用,不报错证明OK。

import scipy

以上也可以,在tfp地址栏输入cmd的方式。【https://www.cnblogs.com/rucwxb/p/7297733.html】

3,安装SKlearn

pip3.6 install C:\Users\lenovo\AppData\Local\Programs\Python\Python36-32\Scripts\scikit_learn-0.19.1-cp36-cp36m-win32.whl

4,安装graphviz  需要添加path。

C:\Program Files (x86)\Graphviz2.38\bin;

C:\Users\lenovo\AppData\Local\Programs\Python\Python36-32\Scripts;

C:\Users\lenovo\AppData\Local\Programs\Python\Python36-32;

C:\ProgramData\Oracle\Java\javapath;

C:\Program Files (x86)\Lenovo\FusionEngine;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;C:\Program Files (x86)\Lenovo\Lenovo Home\;C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\;

C:\Program Files\Microsoft SQL Server\110\Tools\Binn\

dot -Tpdf D:\PycharmProjects2017\DRtee-1\allElectronicInformationGainOri.dot -o outpu.pdf----可以,但是pdf打不开

D:\PycharmProjects2017\DRtee-1>dot _Tpdf allElectronicInformationGainOri.dot -o allElectronicInformationGainOri.pdf

D:\PycharmProjects2017\DRtee-1\dot -Tpdf allElectronicInformationGainOri.dot -o output.pdf---Wrong

D:\PycharmProjects2017\DRtee-1>dot -Tpdf allElectronicInformationGainOri.dot -o outpu.pdf

dot -Tpdf allElectronicInformationGainOri.dot -o outpu.pdf【终于OK!!!】——转换后的文件名字是output.pdf

5,20171210-学习SVM,画图,安装matplotlib

https://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib

pip3.6 install C:\Users\lenovo\AppData\Local\Programs\Python\Python36-32\Scripts\matplotlib-2.1.1-cp36-cp36m-win32.whl

6,20171210-学习SVM,人脸识别,安装pillow;

https://github.com/python-pillow/Pillow

pip3.6 install C:\Users\lenovo\AppData\Local\Programs\Python\Python36-32\Scripts\Pillow-4.3.0-cp36-cp36m-win32.whl
