Barry Hart commented on BEAM-4752:
----------------------------------
Apparently something odd happened when I was installing local Python libraries.
I suspect I got a newer version of {{dill}}, as newer versions have
{{_dill.py}} but not {{dill.py}}.
Closing...

> Key: BEAM-4752
> URL: https://issues.apache.org/jira/browse/BEAM-4752
> Project: Beam
> Issue Type: Bug
> Components: sdk-py-core
> Affects Versions: 2.4.0
> Environment: CentOS Linux release 7.4.1708
> Python 2.7.13
> Reporter: Barry Hart
> Assignee: Ahmet Altay
> Priority: Major
>
> I'm seeing the following error (stack trace below). I looked at the module
> structure of the {{dill}} library, and it does not have a {{dill}} submodule
> (although it *does* have a {{_dill}} submodule). I think the correct way to
> reference {{Pickler}} is simply {{dill.Pickler.}}
> {noformat}
> Traceback (most recent call last):
> File "script/beam_run_model.py", line 29, in <module>
> import apache_beam as beam
> File
> "/usr/local/pyenv/versions/2.7.13/lib/python2.7/site-packages/apache_beam/__init__.py",
> line 84, in <module>
> import apache_beam.internal.pickler
> File
> "/usr/local/pyenv/versions/2.7.13/lib/python2.7/site-packages/apache_beam/internal/pickler.py",
> line 107, in <module>
> dill.dill.Pickler.dispatch[type])
> AttributeError: 'module' object has no attribute 'dill'{noformat}
> Oddly, I have successfully used Beam 2.4.0 in the past with this version of
> Dill. ¯_(ツ)_/¯
