pip3 read time out error

Question

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

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:

Does this answer your question? Pip Install Timeout Issue – Interfile

Answer 1

Setting the default socket timeout to a higher value (e.g. 1000 seconds) should fix your problem:

pip3 install -U --timeout 1000 scikit-learn

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.

Answer 2

Set timeout to a high value. Also it's recommended to run the below command always:

python3 -m pip install --user --timeout 10000 scikit-learn

You maybe asking why should I enter python3 -m as extra and type a few more strings. It's basically to avoid conflicts when you working with multiple virtual environments.

Python core developer Brett Cannon explains why you should install packages like this in his article A quick and dirty guide on how to install python packages.

Answer 3

Setting timeout to a high value is a good solution. In addition, I think that pip install your_package_name from a new useful trusted-host works better. For example:

pip install scikit-learn -i https://www.lfd.uci.edu/~gohlke/pythonlibs/

If you are in China, please use https://pypi.tuna.tsinghua.edu.cn/simple or http://mirrors.aliyun.com/pypi/simple.

If you want the setting above to be valid permanently:

pip config set global.index-url https://www.lfd.uci.edu/~gohlke/pythonlibs/

or you can edit ~/.pip/pip.conf:

[global]
index-url = https://www.lfd.uci.edu/~gohlke/pythonlibs/
[install]
trusted-host = other_useful_urls

Answer 4

Make sure you are using IPV4 and not IPV6.

Answer 5

Sometimes it's nececessary to make some hosts trusted as well: bacause of proxies in some comapnies or service providers.

! pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --timeout 1000 scikit-learn
