Hi Manu, We have added Python 3 environment to our tests see [1], and we are actively making changes to Beam code to make it Python 3-compatible. We are enabling tests module by module, although we have to disable some of the tests initially, when failures are likely introduced in other modules.
I think @RobbeSneyders is currently working on typehints package specifically, as per our Kanban board [2]. If you (or anyone else) is interested in helping with Python 3 support, and has cycles to actively work on it now, please reach out - I would be happy to coordinate the effort, and help with code reviews. Thanks, Valentyn [1] https://github.com/apache/beam/blob/5d298db4c20bbb8876a5b75142341332c1e3fb8d/sdks/python/tox.ini#L56 [2] https://issues.apache.org/jira/secure/RapidBoard.jspa?rapidView=245&view=detail On Thu, Sep 27, 2018 at 3:52 PM Manu Zhang <[email protected]> wrote: > Hi all, > > I failed to run Python tests in 3.7 with the following error. > > File > "/Users/doria/git/incubator-beam/sdks/python/apache_beam/typehints/native_type_compatibility.py", > line 23, in <module> > > import typing > > File > "/Users/doria/git/incubator-beam/sdks/python/.eggs/typing-3.6.6-py3.7.egg/typing.py", > line 1356, in <module> > > class Callable(extra=collections_abc.Callable, metaclass=CallableMeta): > > File > "/Users/doria/git/incubator-beam/sdks/python/.eggs/typing-3.6.6-py3.7.egg/typing.py", > line 1004, in __new__ > > self._abc_registry = extra._abc_registry > > AttributeError: type object 'Callable' has no attribute '_abc_registry' > > This is because the required typing library is not provisional in Python > 3.7 <https://github.com/python/typing#important-dates>. > > Any thoughts on this?
