Bug#896300: python-linop: linop fails to import

[Helmut Grohne]

Package: python-linop
Version: 0.8.2-3
Severity: serious
User: helmutg at debian.org
Usertags: python-import

After installing python-linop importing the module linop
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/linop/__init__.py", line 31, in <module>
    from .linop import *
  File "/usr/lib/python2.7/dist-packages/linop/linop.py", line 32, in <module>
    import numpy as np
ImportError: No module named numpy

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.
