that's a numpy array with sparse data. What @TomNicholas was talking about is a array of type sparse.COO (from the sparse package).

And as far as I can tell, our wrapper class (which is the reason why you don't get the memory error on open) does not define nbytes, so at the moment there's no way to do that. You could try using dask, though, which does allow working with bigger-than-memory data.
