h5py doesnt like gdal

[wvangerwen]

Fresh install of https://github.com/threedi/hhnk-threedi-plugin/blob/main/hhnk_threedi_plugin/env/environment_services.yml without spider using mambaforge results in broken imports,

Somehow still works currently on ota155 broken everywhere else.

Error: Importing h5py and gdal individually works fine. but after each other they do something with dll's.

>>> from osgeo import gdal
>>> import h5py
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\Wietse\mambaforge\envs\threedipy\lib\site-packages\h5py\__init__.py", line 33, in <module>

    from . import h5 as _h5
  File "h5py\h5.pyx", line 1, in init h5py.h5
ImportError: DLL load failed while importing defs: The specified procedure could not be found.

and the other way around

On Windows, with Python >= 3.8, DLLs are no longer imported from the PATH.
If gdalXXX.dll is in the PATH, then set the USE_PATH_FOR_GDAL_PYTHON=YES environment variable
to feed the PATH into os.add_dll_directory().

Reproduce:

mamba env create --file environment_services.yml
conda activate threedipy
python
from osgeo import gdal
import h5py

Possibly to do with h5py being 3.8 while qgis 3.28.5 still uses h4py==2.10.0.

pip install h5py==2.10.0 doesnt work, cant build the wheels.

dependencies.py of ThreeDiToolbox -# On Windows, the hdf5 binary and thus h5py version depends on the QGis version -# QGis upgraded from hdf5 == 1.10.7 to hdf5 == 1.14.0 in QGis 3.28.6 QGIS_VERSION = Qgis.QGIS_VERSION_INT if QGIS_VERSION < 32806 and platform.system() == "Windows": SUPPORTED_HDF5_VERSIONS = ["1.10.7"] H5PY_DEPENDENCY = Dependency("h5py", "h5py", "==2.10.0", False) else: SUPPORTED_HDF5_VERSIONS = ["1.14.0"] H5PY_DEPENDENCY = Dependency("h5py", "h5py", "==3.8.0", True)

Verse installatie met miniforge van environment_services.yml op de ota155 heeft een werkende Threedipy env opgeleverd.
