Description
the example from file "qmcpack-4.1.0/tests/converter/test_LiH_MSD_pyscsf/LiH.py" runs successfully, however, when convert the LiH_multidet.h5 file to qmcpack is wrong. the test text is "convert4qmc -orbitals LiH.h5 -multidet LiH_multidet.h5", the error message shows that "QMCPACK ERROR HDF5 read failure in hdf_archive::read NbDet
Fatal Error. Aborting at Unhandled Exception" . It is same as the error of issue #5563
In addition , we test the text : convert4qmc -orbitals LiH.h5", which can obtain a wavefuction with single determiment.
So how to get a correct wavefuction with multideterminants by PySCF
