[Debian-med-packaging] Bug#896253: python-visionegg: VisionEgg fails to import

[Helmut Grohne]

Package: python-visionegg
Version: 1.2.1-4
Severity: serious
User: helmutg at debian.org
Usertags: python-import

After installing python-visionegg importing the module VisionEgg
into a python interpreter fails with the following error:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/VisionEgg/__init__.py", line 37, in <module>
    import VisionEgg.ParameterTypes as ve_types
  File "/usr/lib/python2.7/dist-packages/VisionEgg/ParameterTypes.py", line 20, in <module>
    import numpy.oldnumeric as numpyNumeric
ImportError: No module named oldnumeric

The vast majority of import failures is attributed to missing dependencies.
Often times that manifests as an ImportError or ModuleNotFoundError.
Typically, dependencies should be inserted by dh-python via ${python:Depends}
or ${python3:Depends}. Thus a missing dependency can be caused by incomplete
install_requires in setup.py. Sometimes a missing dependency of a dependency
is the cause, in such cases this bug should be reassigned.
