CORe50, 10 classes

[DraBard]

Can some1 explain to me why core50 = CORe50(scenario="nc", mini=True, object_lvl=False) (when the dataset has 10 classes) the experiences have the following classes:

exp 0: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
exp 1: [5, 6, 7, 8, 9]
exp 2: [0, 1, 2, 3, 4]
exp 3: [5, 6, 7, 8, 9]
exp 4: [0, 1, 2, 3, 4]
etc ...

Isn't the whole idea of new classes scenario, that each experience has a new class introduced?

Is there an easy way to get to the configuration where each experience has one class only? This is what I need ...

For object_lvl=False it seems to work as expected ...

Hi @Bard2803, you are right, this may be a possible bug!

Sure, we recommend using the benchmark generators for this: https://avalanche.continualai.org/from-zero-to-hero-tutorial/03_benchmarks#benchmarks-generators
