I can confirm that there is a bug in `PythonPlanBinder.java`. When you pass
packages to the `runPlan()` function, they are not copied to the temp directory
in which `plan.py` file is generated. I manually changed the `prepareFiles()`
call to copy the package files, and everything worked fine.
Should I open another issue, or just fix it here? This is not only a bug
related to the testing infrastructure, but the Python API in general.
