Prerequisite environment (according to the installation of the subject):
python3.7
Windows10
First of all, to download the three kinds of packages for https://www.lfd.uci.edu/~gohlke/pythonlibs/(if you want to download other packages, you can find and then the next), the download should be aware that you must first download a good NumPy package, Download the Scipy,sklearn package in turn, and note that the download and your Python, computer corresponding version, for example, my Python version is 3.7, the computer is 64-bit, then I choose to download is numpy-1.14.3+ Mkl-cp37-cp37m-win AMD64.WHL this version; If your computer is 32-bit, select Download numpy-1.14.3+ MKL-CP37-CP37M-WIN32.WHL; If Python is version 2.7 and the computer is 64-bit, select Download Numpy-1.14.3+mkl-cp27-cp27m-win AMD64.WHL this version. Other, and so on, scipy and Sklearn version of the same way to infer their own.
The three kinds of bags that I've been doing,
After the download, in the cmd into the pip path, my pip.exe is under the Python scripts, and then enter the command pip3.7 install +numpy storage path (You can enter "pip3.7 install" After direct click NumPy Drag to cmd window as shown, that is, I installed the Numpy,scipy,sklearn process is the result, has shown "successfully installed ...", I ignored the PIP version of the problem, It says that the PIP version can be upgraded to a higher version, but it does not affect the installation, so it will be upgraded later.
After installing with PIP, enter the command PIP list to see the packages that have been installed
At this point, the installation is complete, and if you want to install Python's other packages, the process is similar.
