Using hodmd with parametric rom for 1D snapshots - ValueError: not enough values to unpack (expected 3, got 2)

[zonexo]

I want to use hodmd with parametric rom for 1D snapshots. However, the snapshots in hodmd use array of length (timestep_size,), unlike standard dmd, which uses (data_size,timestep_size)

Hence, when I use hodmd with parametric rom, I got the error msg:

ValueError: not enough values to unpack (expected 3, got 2)

So how should I solve it? Should I use a training_snapshots of array size (total_cases,1,timestep_size)? I tried and there's no error msg but I wonder if it's the correct way.

Please clarify. Thank you!
