1, first download Numpy, MatplotLib these two libraries, web site https://www.lfd.uci.edu /~ Gohlke/pythonlibs/, my is python3.5 64bit, so the download is the numpy-1.13.3 + mkl-cp35-cp35m-win amd64.whl

If the version is incorrect, an error is reported during installation.

　　

2, cmd, then cd to pip install numpy-1.13.3 + mkl-cp35-cp35m-win amd64.whl path, Through pip install numpy-1.13.3 + mkl-cp35-cp35m-win amd64.whl installation (Supplement: The premise is that pip has been installed, and set the environment variables. pip is in the scripts directory of the python installation directory)

Then cmd, then pip install-I https://pypi.tuna.tsinghua.edu.cn/simple numpy, so that the image from Tsinghua side to install the numpy library ..

If you want to use pip more conveniently next time, create a pip directory in the user directory, for example, C: \ Users \ xx \ pip. Create the pip. ini file. The content is as follows:
