{code}
I suspect this is because {{setuptools_scm}} isn't being used correctly. All
the documentation says to use {{get_version()}} and the package author doesn't
seem to be sure that {{version_from_scm()}} should even be a public function
(see
[here|[https://github.com/pypa/setuptools_scm/blob/master/src/setuptools_scm/__init__.py#L27]).]
Perhaps using the standard function would fix the issue?
