Proper way to parse requirements file after pip upgrade to pip 10.x.x?

Question

So today I did found out that with the release of pip 10.x.x the req package changed its directory and can now be found under pip._internal.r

I don't agree with the accepted answer. The setup.py file can get ugly real fast if you have a large project with a lot of dependencies. It is always good practice to keep your requirements in a separate .txt file. I would do something like this -

try:  # for pip >= 10
    from pip._internal.req import parse_requirements
    from pip._internal.download import PipSession
except ImportError:  # for pip <= 9.0.3
    from pip.req import parse_requirements
    from pip.download import PipSession

requirements = parse_requirements(os.path.join(os.path.dirname(__file__), 'requirements.txt'), session=PipSession())

if __name__ == '__main__':
    setup(
        ...
        install_requires=[str(requirement.requirement) for requirement in requirements],
        ...
    )

Throw in all your requirements in requirements.txt under project root directory.
