[jira] [Created] (BEAM-11623) Verify that Python version used to launch pipeline matches the Python version that runs sdk_worker.

Valentyn Tymofieiev created BEAM-11623:
------------------------------------------

             Summary: Verify that  Python version used to launch pipeline matches the Python version that runs sdk_worker.
                 Key: BEAM-11623
                 URL: https://issues.apache.org/jira/browse/BEAM-11623
             Project: Beam
          Issue Type: Bug
          Components: sdk-py-core
            Reporter: Valentyn Tymofieiev


We should verify that (major.minor) Python version at launch time matches the version on the workers, and alert users with an error when this is not the case.
Otherwise the job may fail with cryptic errors during DoFn un-pickling such as 'SystemError: unknown opcode'.
