Marco Buccini commented on BEAM-517:
------------------------------------
So, from my understanding we could specify the requirements for PIP in setup.py
with the following:
import pkg_resources
assert str(pkg_resources.get_distribution('pip').version) >= '7.0.0', "This SDK
requires 'pip' >= 7.0.0"
while mentioning it in the README file.
(it seems that the --no-binary flag was introduced in version 7.0.0:
https://pip.pypa.io/en/stable/news/ )
Regarding cython, I am not quite sure about the version needed to run the code,
so probably someone else might be able to tell more about it.
> Check versions of pip and cython

> Python SDK depends on pip and cython however it does not check the versions
> of these.
> Some of the pip flags does not exist in older versions:
> https://github.com/GoogleCloudPlatform/DataflowPythonSDK/issues/28#issuecomment-236382953
> (Note: Even though the above issue was reported by the user in a different
> repo it is related to the apache beam sdk)
> Similarly with cython, SDK supports running with or without Cython. Because
> of that reason it is not list it as a requirement in the setup.py file.
> However, with an old version of cython SDK might fail.
> To avoid the above problem: In the SDK check the version of these packages
> and show a warning to upgrade.
