There is currently an issue which leads to a crash of the Python Kernel when running CADET on Windows.
After some digging, we found out that the issue comes with one of our dependencies, namely hdf5/h5py.
When HDF5 v1.12.2 was released, h5py seems to not have properly included the new headers. Which leads to the following error:
Warning! ***HDF5 library version mismatched error*** The HDF5 header files used to compile this application do not match the version used by the HDF5 library to which this application is linked. Data corruption or segmentation faults may occur if the application continues. This can happen when an application was compiled by one version of HDF5 but linked with a different version of static or shared HDF5 library. You should recompile the application or check your shared library related settings such as 'LD_LIBRARY_PATH'. You can, at your own risk, disable this warning by setting the environment variable 'HDF5_DISABLE_VERSION_CHECK' to a value of '1'. Setting it to 2 or higher will suppress the warning messages totally. Headers are 1.12.2, library is 1.12.1
We know other projects seem to have the same issue and we contacted the h5py developers.
In the meantime, for a quick fix, simply downgrade h5py:
pip uninstall h5py pip install h5py==3.6.0
We’re also working on a new hotfix release of CADET-Python which will put bounds on the h5py version until the issue is resolved upstream.
Thanks for understanding!
