    HTTP errors are often intermittent, and a simple retry will get you on your way.

    If your current network has https://www.anaconda.com blocked, please file
    a support request with your network engineering team.

    SSLError(MaxRetryError("HTTPSConnectionPool(host='repo.anaconda.com', port=443): Max retries exceeded with url: /pkgs/main/win-64/repodata.json.bz2 (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1045)')))"))
    解决办法:

    Pycharm中配置cando环境

    Page01.py文件:
    # coding:utf-8
    from matplotlib import pyplot as plt

    x = range(2, 26, 2)
    y = [15, 13, 14.5, 17,20,25,26,26,24,22,18,15]
    plt.plot(x,y)
    plt.show()


    运行简单的画图效果程序报错:
    D:pythonchuanzhi_15>python page01.py

    raise ImportError(msg)
    ImportError:
    Importing the multiarray numpy extension module failed. Most
    likely you are trying to import a failed build of numpy.
    If you're working with a numpy git repo, try `git clean -xdf` (removes all
    files not under version control). Otherwise reinstall numpy.

    Original error was: DLL load failed: 找不到指定的模块。


    画图效果

    解决办法将D:ProgramDataAnaconda3Libraryin加入环境变量:
