ADIOS ImportError is being ignored

An ImportError caused by a missing ADIOS installation is not handled. This leads to errors with the ADIOS datasets further in the code. https://github.com/ORNL/HydraGNN/blob/main/hydragnn/utils/adiosdataset.py#L300

NameError: name 'ad2' is not defined

We put try ... except block in the code to make HydraGNN work even without adios2 python module. When there is no adios2 python module and someone is trying to use adios related work, it will make such error.

On Frontier, I recommended people to use the following command:

module swap PrgEnv-${PE_ENV,,} PrgEnv-gnu
module load rocm/5.3.0
module load cmake
module load craype-accel-amd-gfx90a
module unload darshan-runtime

module use -a /lustre/orion/world-shared/phy122/jyc/frontier/sw/modulefiles
module load anaconda3/2022.10
module load adios2/devel

Now I recommend to use the following:

module load adios2/v2.8.3

or

module load adios2/v2.9.0

@kshitij-v-mehta @jychoi-hpc Is this issue still relevant or can we close it?

[kshitij-v-mehta]

It is still open. We need to add a clear error message when someone tries to use ADIOS when it is not installed.
