Numpy.core.getlimits.py UserWarning: The value of the smallest subnormal for <class 'numpy.float32'> type is zero.

[oschwengers]

Unfortunately, somewhere on the last mile towards v1.10.0, the following numpy UserWarning started to appeared in each invocation of Bakta:

conda-envs/bakta-test/lib/python3.11/site-packages/numpy/_core/getlimits.py:555: UserWarning: The value of the smallest subnormal for <class 'numpy.float32'> type is zero.
  setattr(self, word, getattr(machar, word).flat[0])
conda-envs/bakta-test/lib/python3.11/site-packages/numpy/_core/getlimits.py:89: UserWarning: The value of the smallest subnormal for <class 'numpy.float32'> type is zero.
  return self._float_to_str(self.smallest_subnormal)
conda-envs/bakta-test/lib/python3.11/site-packages/numpy/_core/getlimits.py:555: UserWarning: The value of the smallest subnormal for <class 'numpy.float64'> type is zero.
  setattr(self, word, getattr(machar, word).flat[0])
conda-envs/bakta-test/lib/python3.11/site-packages/numpy/_core/getlimits.py:89: UserWarning: The value of the smallest subnormal for <class 'numpy.float64'> type is zero.
  return self._float_to_str(self.smallest_subnormal)

As reported in #346 and discudded here, it seems to be related to some ffast-math compilation flag set by any of Bakta's dependency - or dependency's dependency...

If someone has an idea or solution how to solve or circumvent this, please let us know.
