The following prompt appears to indicate successful installation:
Three Installing NumPy
Download the corresponding version number on the official website:
https://pypi.python.org/pypi/numpy/1.10.4
http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
(PS: The official web page seems to find the older version, I myself was found on the CSDN a resource bundle downloaded: http://download.csdn.net/download/pleaseandplease/ 9387857, download this package: NUMPY-1.10.2+MKL-CP27-NONE-WIN_AMD64.WHL)
After downloading it into a fixed directory, use the command pip install NUMPY*.WHL to install, after successful results are as follows:
You can also see the post-installation version using the PIP list:
Import uses normal
Four Installing scipy
Download the corresponding WHL installation package online, such as:
Scipy-0.15.1-cp27-none-win_amd64.whl
There is currently only a newer version of the official website, the 1.5 version is not provided, I was downloaded on the micro disk, the connection is as follows:
Http://vdisk.weibo.com/s/Dp2sFMRNcCOI
There is only a newer version of the WHL package on the official website.
After downloading, refer to the way above, using PIP to install, the successful prompt is as follows:
The Pip list can also see the installed version
Import use test OK
Five Installing Matplot
Similar to the previous step, download the corresponding WHL version, such as:
Matplotlib-1.5.0-cp27-none-win_amd64.whl
The official web site also seems to be not under the old version, I am in this connection up and down:
http://zh.osdn.net/projects/sfnet_matplotlib/downloads/matplotlib/matplotlib-1.5.0/windows/ matplotlib-1.5.0-cp27-none-win_amd64.whl/
Install using PIP install, after successful following prompt:
When installing Matplot, some dependent packages, such as Dateutil, are installed, and a number of new packages are added with the PIP List view:
Use Import to use OK
>>> Import Matplotlib.pyplot as Plt >>> Plt.plot ([+]) [<matplotlib.lines.line2d object at 0x00000000079e9be0>] >>> Plt.show () |
Six Installing Scikit-learn
To the official website to download the corresponding WHL version,
Https://sourceforge.net/projects/scikit-learn/files/?source=navbar
For example, use this version:
To install using the PIP Install command, the following is successful:
PIP list See installed version
Use Import to test OK
Seven Installing Pandas
Go to official website http://pandas.pydata.org/ find the corresponding version link
Download the corresponding wheel version:
Use pip install to install
PIP list See version
Import uses normal
Eight All installation Packages
The list of all packages that need to be installed is as follows:
Numpy+pandas+scipy+matplotlib+scikit-learn installation of Python data analysis
