问题描述
sudo pip3 install scikit-learn (实际上只是使用最新尝试的任何模块)
sudo pip3 install scikit-learn (any module really just using most recent attempt)
sudo pip3 install -U scikit-learn
sudo -H pip3 install -U scikit-learn
sudo -H pip3 --default-timeout=200 install -U scikit-learn
sudo python3 -m pip install scikit-learn
每个命令以及上面的任何组合都会导致相同的错误:读取超时.该错误总是在同一点发生(scikit-learn发生在24％).我正在使用最新版本的pip(8.1.2)，并且正在使用ubuntu mate 16.04.确切的错误是:
every command and any combination of the above results in the same error: Read timed out. The error always occurs at the same point (scikit-learn happens at 24%). I am using the latest version of pip(8.1.2) and I am on ubuntu mate 16.04. The exact error is:

推荐答案
将默认套接字超时设置为更高的值(例如1000秒)应该可以解决您的问题:
Setting the default socket timeout to a higher value (e.g. 1000 seconds) should fix your problem:
pip3 install -U --timeout 1000 scikit-learn
当然，合适的超时值取决于您的连接速度和质量.请注意，套接字超时AFAIK是套接字级别数据流在引发错误之前中断的最长时间，而不是下载软件包所需的总时间.
The suitable timeout value, of course, depends on your connection speed and quality. Note that the socket timeout, AFAIK, is the maximum time the socket-level data flow is interrupted before an error is raised, not the total time needed to download packages.
