安装NNI时候遇到的问题

第一是

 install_requires = [
        'astor',
        'hyperopt==0.1.2',
        'json_tricks',
        'netifaces',
        'numpy',
        'psutil',
        'ruamel.yaml',
        'requests',
        'scipy',
        'schema',
        'PythonWebHDFS',
        'colorama',
        'scikit-learn>=0.20,<0.22',
        'pkginfo',
        'websockets'
    ],

没有符合scikit-learn>=0.20,<0.22’

PermissionError: [WinError 5] 拒绝访问。: ‘c:\programdata\anaconda3\lib\site-packages\pip-18.0.dist-info\entry_points.txt’
