(This is the error i get after run create_stateful_dataset.py with the dataset downloaded from youtube. Then i try to troubleshoot it and i found the problem is from data.py as i get "None" for variable output:

for start_frame in start_frames:
    # Obtain the label for this isntance and then its output
    output = None

    outs = outputs[start_frame:start_frame+length]
    if outs.count(label) >= length / 2:
        output = labels.index(label)
    else:
        output = labels[0] <----------------------it will jump to this everytime i run create_stateful_dataset.py
    instances.append(output)

Try to update the code to the latest version, I think previous people commented this issue and it has been fixed.

@albertomontesg @fitrialif I also meet this error when i running the create_stateful_dataset.py,my error is assert nb_instances == len(output_classes), i have update the code to the latest version
