Unable to open HDF5 dataset: time_slice error

[prasad-sawantdesai]

Opening dataset_description ids with equilibrium, reading variables with HDF5 fails?

    import imaspy as imas
except ImportError:

try:
    ids_equilibrium = connection.get("equilibrium", autoconvert=False, lazy=True, ignore_unknown_dd_version=True)
except Exception as e:

for t in ids_equilibrium.time_slice:
