dependencies missing (numpy, hd5py, ...)

[Kwasniok]

Hi, I freshly installed it via pip and numpy, h5py etc. seem to be missing.

Reproduction (Linux):

python -m venv venv
. venv/bin/activate
pip install openpmd-beamphysics
python -c "from pmd_beamphysics import ParticleGroup"

Result:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
    from pmd_beamphysics import ParticleGroup
  File "***/lib/python3.13/site-packages/pmd_beamphysics/__init__.py", line 1, in <module>
    from .fields.fieldmesh import FieldMesh
  File "***/lib/python3.13/site-packages/pmd_beamphysics/fields/fieldmesh.py", line 5, in <module>
    import numpy as np
ModuleNotFoundError: No module named 'numpy'

Version:

python --version
Python 3.13.5
pip freeze
openpmd-beamphysics==0.10.2

Workaround?:
Use

pip install pmd-beamphysics

When I added the following other packages the error went away:

numpy
h5py
scipy
matplotlib
