How to create the plots in the demo videos?

[gitreset-hard]

I see there beat plot and downbeat plot, how can I create this? adding the type of plots changed nothing for the output. Just getting started using this library

estimator = BeatNet(1, mode='offline', inference_model='DBN', plot=["downbeat_particles","activations","beat_particles"], thread=False)
Output = estimator.process(song_path)
