【pip conda】第三方库无法安装

pip加速 #pip换源
conda下无法安装第三方库 Could not find a version that satisfies the requirement numpy
具体问题：
Could not fetch URL https://pypi.tuna.tsinghua.edu.cn/simple/pylint/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host=’pypi.tuna.tsinghua.edu.cn’, port=443): Max retries exceeded with url: /simple/pylint/ (Caused by SSLError(SSLEOFError(8, ‘EOF occurred in violation of protocol (_ssl.c:852)’),)) - skipping

pip install numpy -ihttp://pypi.douban.com/simple/--trusted-host pypi.douban.com
换成国内源就可以了
pip install incremental -ihttp://pypi.douban.com/simple/--trusted-host pypi.douban.com

pip install numpy —user —trusted-host pypi.python.org —依旧报错

pytorch环境下，使用pip或者conda命令无法安装，需要后面加源
