Sep 20th, 2022 (OLCFHELP-8992):
The above **HDF5 Jupyter read** work-around for OLCFHELP-3685 does not work anymore, due to the way that GPFS is mounted via NSF on Jupyter nodes.
As a work-around until this is fixed, please copy your HDF5 data to ``/ccs``, ``$HOME`` or use ADIOS2 BP instead of HDF5 files.
