Group name acquisition and no lazy loading problem #2097

Closed ezeli closed 2 years ago

ezeli commented 2 years ago

When opening the hdf5 file, you must specify the group name defined at the time of creation. How should I obtain this group name if I have forgotten it ? Another question is when opening hdf5 files, how to load them into memory all at once without lazy loading ? Thank you !
