I have been using Python for nearly a year, using Python 3.4, and recently wanted to upgrade my Python environment to the latest Python 3.6
Operating system windows8.1 64-bit
1. Download the installation package from the official website and click install
Check the options. If you do not check the options, you need to install them yourself
After installation, click Finish
I downloaded the 32-bit version of Python from the official website. Please be sure to match it when installing various installation packages in the future. Otherwise, errors will be reported
It will automatically add Python to the environment variable and verify the installation by typing Python on the command line after the installation is complete.
2. Install Numpy
PIP install numpy can be used to install numpy
3. Install SCIpy
Error: PIP install scipy
Scipy cannot be installed directly through PIP on Windows
Go to http://www.lfd.uci.edu/~gohlke/pythonlibs/ to download the installation file
Note that the version I chose is 32-bit, which matches my Python
And then install this. WHL
Note that the absolute path is entered
Test scipy after successful installation
Error while calling scipy, message above. The reason is that SCIpy relies on numpy and MKL, and numpy installed through PIP lacks MKL
So uninstall Numpy and scipy
Go to the url above to download the corresponding version of Numpy
Reinstall Numpy, and note that mine is the 32-bit version
Scipy was then installed and tested successfully
4. Install sciKit-learn
Download the corresponding version of SciKit-learn from the url above and install it in the same way
5. Install Matplotlib
Run the PIP install matplotlib command to install it
Install ipython
Install directly from the PIP install ipython command
