Subject [jira] [Commented] (BEAM-4752) Import error in apache_beam.internal.pickler: "'module' object has no attribute 'dill'"
Date Tue, 10 Jul 2018 19:29:00 GMT

    [ https://issues.apache.org/jira/browse/BEAM-4752?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16539141#comment-16539141
] 

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...

> 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)_/¯
