TypeError: ' RadarPointCloud ' object is not iterable

[Tipper-sun]

When the training starts，i met this problem:

radar_sample = [radar.enrich_radar_data(pc.points) for pc in pcs]
TypeError: 'RadarPointCloud' object is not iterable

RadarPointCloud:
pcs, times = RadarPointCloud.from_file_multisweep(self.nusc, sample, sensor_channel,
sensor_channel, nsweeps=required_sweep_count,
min_distance=0.0)

you can transform pcs in 'radar_sample = [radar.enrich_radar_data(pc.points) for pc in pcs]' to list before iterate.
such as :

pcs = list(pcs)
radar_sample = [radar.enrich_radar_data(pc.points) for pc in pcs]
