[Python-modules-team] Bug#896370: python-feather-format: feather fails to import

[Helmut Grohne]

Package: python-feather-format
Version: 0.3.1+dfsg1-1
Severity: serious
User: helmutg at debian.org
Usertags: python-import

After installing python-feather-format importing the module feather
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/feather/__init__.py", line 17, in <module>
    from feather.api import read_dataframe, write_dataframe
  File "/usr/lib/python2.7/dist-packages/feather/api.py", line 15, in <module>
    import six
ImportError: No module named six

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.
