David Sabater commented on BEAM-3343: ------------------------------------- In case it helps. I had the same issue after the fix adding the upper bound in Protobuf. I solved the issue in my local environment by downgrading Protobuf installed in my virtualenv from 3.5 to 3.4. Kind regards. > beam_PostCommit_Python_Verify fails due to "ImportError: cannot import name > coder_impl" > --------------------------------------------------------------------------------------- > > Key: BEAM-3343 > URL: https://issues.apache.org/jira/browse/BEAM-3343 > Project: Beam > Issue Type: Bug > Components: sdk-py-core > Reporter: Chamikara Jayalath > Assignee: Robert Bradshaw > Priority: Critical > Fix For: Not applicable > > > First occurred for pull request https://github.com/apache/beam/pull/4220 > https://builds.apache.org/job/beam_PostCommit_Python_Verify/3723/console > Robert, can you take a look ? -- This message was sent by Atlassian JIRA (v6.4.14#64029)
