[Debian-astro-maintainers] Bug#950033: missing dependencies on python3-healpy and python3-tk

[Christoph Berg]

Package: pymoctool
Version: 0.5.0-4
Severity: normal

pymoctool is missing dependencies on python3-healpy and python3-tk:

$ pymoctool ../cepheiden.moc --plot
Traceback (most recent call last):
  File "/usr/bin/pymoctool", line 40, in <module>
    main()
  File "/usr/bin/pymoctool", line 33, in main
    tool.run(sys.argv[1:])
  File "/usr/lib/python3/dist-packages/pymoc/util/tool.py", line 111, in run
    self.command[p](self)
  File "/usr/lib/python3/dist-packages/pymoc/util/tool.py", line 380, in plot
    from .plot import plot_moc
  File "/usr/lib/python3/dist-packages/pymoc/util/plot.py", line 16, in <module>
    import healpy
ModuleNotFoundError: No module named 'healpy'

... installing python3-healpy:

$ pymoctool ../cepheiden.moc --plot
Traceback (most recent call last):
  File "/usr/bin/pymoctool", line 40, in <module>
    main()
  File "/usr/bin/pymoctool", line 33, in main

    switch_backend(rcParams["backend"])
  File "/usr/lib/python3/dist-packages/matplotlib/pyplot.py", line 221, in switch_backend
    backend_mod = importlib.import_module(backend_name)
  File "/usr/lib/python3.7/importlib/__init__.py", line 127, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
  File "/usr/lib/python3/dist-packages/matplotlib/backends/backend_tkagg.py", line 1, in <module>
    from . import _backend_tk
  File "/usr/lib/python3/dist-packages/matplotlib/backends/_backend_tk.py", line 6, in <module>
    import tkinter as tk
ModuleNotFoundError: No module named 'tkinter'

... after installing python3-tk, rendering works.
