Stephan Hoyer created BEAM-12234:
------------------------------------
Summary: README example for Beam Python InteractiveRunner is broken
Key: BEAM-12234
URL: https://issues.apache.org/jira/browse/BEAM-12234
Project: Beam
Issue Type: Bug
Components: runner-py-interactive
Affects Versions: 2.28.0
Reporter: Stephan Hoyer
Running the example from the interactive Beam README doc [1] produces an error:
{code:python}
import apache_beam as beam
from apache_beam.runners.interactive.interactive_runner import InteractiveRunner
p = beam.Pipeline(InteractiveRunner())
pcoll = p | beam.Create([1, 2, 3])
result = p.run().wait_until_finish()
pcoll_list = result.get(pcoll) # This returns a list!
{code}
Results in:
{{code}}
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
<ipython-input-11-b3606ce83458> in <module>()
2 pcoll = p | beam.Create([1, 2, 3])
3 result = p.run().wait_until_finish()
----> 4 pcoll_list = result.get(pcoll) # This returns a list!
AttributeError: 'NoneType' object has no attribute 'get'
{{code}}
Side note: I had to look-up the import statements here. As long as you're
updating the example, it would be nice for it to be runnable with copy & paste.
