             Summary: virtualSetupEnv task is flaky
                 Key: BEAM-8194
                 URL: https://issues.apache.org/jira/browse/BEAM-8194
             Project: Beam
          Issue Type: Bug
          Components: sdk-py-core
            Reporter: Ahmet Altay
            Assignee: Valentyn Tymofieiev


PyPI sometimes fails when it cannot find dependencies. This happens even when dependencies exist.

Example: https://builds.apache.org/job/beam_PostCommit_Python2/433/consoleFull

Log: 
05:00:54 Collecting filelock<4,>=3.0.0 (from tox==3.11.1)
05:00:54   ERROR: Could not find a version that satisfies the requirement filelock<4,>=3.0.0 (from tox==3.11.1) (from versions: none)
05:00:54 ERROR: No matching distribution found for filelock<4,>=3.0.0 (from tox==3.11.1)

05:00:57 > Task :sdks:python:setupVirtualenv FAILED

There was a previous attempt to fix this (https://github.com/apache/beam/pull/7519/files) by adding `--retries 10` to the pip command. However, this only works with connections (https://pip.pypa.io/en/stable/reference/pip/#cmdoption-retries) and I am guessing that when pip decides that a dependency does not exist it requires more than a network retry.

We could try a gradle task level retry, or wrap the virtualenv creation in a shell script and try do a retry on that.
