Pip install forked github-repo

Question

I'm working on a project and need a little different functionality from the package sklearn. I've forked the repo and pushed my changes. I know that I can install from github via pip:

pip install git+git://github.com/wdonahoe/scikit-learn-fork.git@master

and then I can install the package with setup.py:

python setup.py install

However, I am confused about what to do after this step. Running setup.py creates some .egg-info folders and .egg-links files in .../dist-packages/, but I am unsure what to do with them. Ideally, I'd like to go into my project in .../projects/my_project and say something like

from sklearn-my-version import <stuff>

or switch it out with just

from sklearn import <stuff>

I am also a little confused because a lot of resources on this issue mention using easy_install, which I thought pip replaced.

First, you don't want to do both installs on the same package. Either `pip install git+…` or `python setup.py install` (or `pip install .`), not both. — abarnert, May 17 '15 at 20:58
Meanwhile, either one of those will install the package into your (system, user, or virtualenv) dist-packages or site-packages. (It doesn't go anywhere inside your project. If that's what you think you want, most likely what you actually want is a virtualenv.) You can just `import` the package the same way as any other package. Assuming it installed as `sklearn`, you can just do `from sklearn import `, which sounds like exactly what you want to do, so what's the problem? — abarnert, May 17 '15 at 21:00
Finally, the reason "a lot of resources" mention `easy_install` is that a lot of resources are years out of date. If you're reading old StackOverflow answers, blog posts, printed books, etc., they're unlikely to have been updated since they were initially written. — abarnert, May 17 '15 at 21:01

try again using just (-e flag lets you git pull updates by installing it as a git repo)

pip install -e git+git://github.com/wdonahoe/scikit-learn-fork.git@master#egg=scikit-learn

Great hint about the `-e` option! – Paolo Stefan Apr 21 '16 at 08:48

When I do this it creates a `/src` to the install in my current directory. Where is the best place to run these commands from? – lacostenycoder Jan 07 '21 at 20:28
how do I install from an ssh only repo? – pythonian29033 Apr 20 '22 at 12:23
@pythonian29033: This one is outdated, try this: https://stackoverflow.com/a/50141879/5290519 – NeoZoom.lua May 19 '22 at 01:01
@lacostenycoder try using a virtual environment. Then the install will put this in `./env/src/...` – nschmeller Aug 05 '22 at 21:42
