Code0x58 opened a new issue #3558: URL: https://github.com/apache/incubator-heron/issues/3558
While upgrading from python2 to python3, the generated PEXs would not work due to being unable to import from at least `pex_library` includes, related to the introduction of [PEP-420](https://www.python.org/dev/peps/pep-0420/), but for some reason wasn't working with the default `zip_safe=None`/`zip_safe=True`, so the workaround was to cause the PEXs to always be extracted to disk rather than loaded straight into memory. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
