    DEPRECATED: dependency_links doesn't work
    Enables both "pytorch>=0.2" and "git+ssh://..." style links to work
    You can list both in requirements.txt, which is not supposed to be the same
    as listing requires in setup.py
    Don't forget to append "#egg=pytorch-0.2" to the end of the github src link
    Turns out that as well as a dependency_links line, we also need to add the
    name of the package in the install_requires line
