So declaring a conflict on setuptools-scm may be a bit tricky, since it is
also listed in the upstream's pyproject.toml file, although, of course,
it may be patched out. If anything, a conflict should be declared against
the "git" package :)

However, it seems the upstream build actually depends on setuptools-scm now,
they (you? :)) don't use any other way to tell the build system about
the data files - the *.png images, the *.rst documentation, etc..
This... may be a problem if the package is not built out of a Git checkout
with Git itself present... and Debian packages are usually expected to be
built out of a plain extracted source archive, no `.git/`, no anything.

I'd suggest making some changes upstream, like listing the data files yourself:
  https://setuptools.pypa.io/en/latest/userguide/datafiles.html

(or, of course, switching away from setuptools, but any build system you choose
 may still need to be configured to include the data files along with your
 Python module sources, although some of them do this by default for most files)

G'luck,
Peter
