Can't work out how to use SEED dataset de

[AnoderPersona]

Hello, I was trying to run the pre-trained model with the SEED-V de-features, however I can't seem to work it out. I used the .ipynb that comes with the dataset to try and use the features with the model, but the ones that come with the dataset are in .npz and the ones that de model asks for are .npy. I tried extracting both the label and the data divided by the sessions, but when running the bash command for the first line of local_run, it gives me the error:

When printing the length of the resulting .npy it does give me different values.
Could someone please help me, I'm interested in using this model for my thesis project.
I would upload more images about the code, but I'm afraid I may be going against SEED-V rules.
