>
> Key: BEAM-4025
> URL: https://issues.apache.org/jira/browse/BEAM-4025
> Project: Beam
> Issue Type: Bug
> Components: sdk-py-core
> Affects Versions: 0.6.0, 2.0.0, 2.1.0, 2.2.0
> Reporter: Taylor Edmiston
> Priority: P3
>
> Beam does not currently support Python 3, however, it's possible to install
> _some versions_ from PyPI / Warehouse under Python 3 today. (It appears the
> config was fixed after 2.2.0 -
> https://github.com/apache/beam/commit/807b4bcefd877440c12f7fc3b401446e21899904.)
> This affects the following 5 versions:
> {code:java}
> $ pip3 install apache-beam==-1
> Collecting apache-beam==-1
> Could not find a version that satisfies the requirement apache-beam==-1
> (from versions: 0.6.0, 2.0.0, 2.1.0, 2.1.1, 2.2.0)
> No matching distribution found for apache-beam==-1{code}
> This is a confusing experience for users (customers) to discover that it's
> incompatible only on import after installing the package (and not reading the
> docs) via the error message:
> {code:java}
> RuntimeError: The Apache Beam SDK for Python is supported only on Python 2.7.
> It is not supported on Python [sys.version_info(major=3, minor=6, micro=4,
> releaselevel='final', serial=0)].{code}
> Since it's not compatible anyway, it's confusing that the non-working package
> versions are installable.
> I don't think there's an easy way to remove just the Python 3 build from the
> wheels or in the PyPI GUI. As far as I can tell, this would require
> rebuilding + re-uploading the Python 2 wheels for affected versions.
