Pybindings on ubuntu

[fiedl]

While the pybindings are working on macos with icesim V05-00-07, I experience some issues when using ubuntu.

TypeError: No to_python (by-value) converter found

For example, when running ./generateTestFlashesSC.py of the StandardCandle script I get

Traceback (most recent call last):
  File "./generateTestFlashesSC.py", line 32, in <module>
    from icecube import icetray, dataclasses, dataio, phys_services, clsim, sim_services
TypeError: No to_python (by-value) converter found for C++ type: I3Map<OMKey, std::vector<I3MCPE, std::allocator<I3MCPE> > >

when the python modules are imported like usual in this script: from icecube import icetray, dataclasses, dataio, phys_services, clsim, sim_services.

When I change this to

from icecube import icetray, dataclasses, simclasses
from icecube import dataio
from icecube import phys_services, sim_services
from icecube import clsim

the above issue is gone. I had to split-up the imports and to import simclasses as well.

But this leads to an even stranger issue:

AttributeError: 'module' object has no attribute 'StandardCandleFlasherPulseSeriesGenerator'

When changing the import as shown above, calling ./generateTestFlashesSC.py leads to:

Traceback (most recent call last):
  File "./generateTestFlashesSC.py", line 63, in <module>
    tray.AddModule(clsim.StandardCandleFlasherPulseSeriesGenerator, "StandardCandleFlasherPulseSeriesGenerator",
AttributeError: 'module' object has no attribute 'StandardCandleFlasherPulseSeriesGenerator'

And, sure enough, if I try to inspect clsim, StandardCandleFlasherPulseSeriesGenerator as well as some other stuff from https://github.com/claudiok/clsim/blob/master/python/__init__.py is missing.

>>> print dir(clsim)
['I3CLSimEventStatistics', 'I3CLSimFlasherPulse', 'I3CLSimFlasherPulseSeries', 'I3CompressedPhoton', 'I3CompressedPhotonSeries', 'I3CompressedPhotonSeriesMap', 'I3ExtraGeometryItem', 'I3ExtraGeometryItemConstPtrVect', 'I3ExtraGeometryItemCylinder', 'I3ExtraGeometryItemMove', 'I3ExtraGeometryItemUnion', 'I3Photon', 'I3PhotonSeries', 'I3PhotonSeriesMap', 'I3ShadowedPhotonRemover', '__doc__', '__file__', '__name__', '__package__', 'converters', 'std_map_indexing_suite_I3CompressedPhotonSeriesMap_entry', 'std_map_indexing_suite_I3PhotonSeriesMap_entry']

How to reproduce

The easiest way to reproduce this is using the ubuntu-icecube-soft docker image. This uses icesim V05-00-00, but I've also installed V05-00-07 with the same result.

docker run -it tpalczew/ubuntu-icecube-soft bash
cd /icesim/V05-00-00/build
source env-shell.sh
cd /icesim/V05-00-00/src/clsim/resources/scripts/flasher/StandardCandle
./generateTestFlashesSC.py
