Hi, thank you for sharing and maintaining an amazing dataset.
I am trying to use utilize a segmentation mask for the detection task.
To do that, I want to get the nuim segmentation mask from nusc ‘sample_data’.
nusc_sample = nusc.get(‘sample’, nusc_sample_token)
nusc_cam_token = nusc_sample[‘data’][‘CAM_FRONT’]
nusc_sample_data = nusc.get(‘sample_data’, nusc_cam_token)
semantic_mask, instance_mask = nuim.get_segmentation(nusc_cam_token)
As I understood from the tutorial and schema, nusc and nuim share sample_data tokens.
However, when I try to get nuim data from nusc token, nusc token is not listed in nuim ‘sample_data’ dictionary key.
Am I doing something wrong or nusc and nuim do not share sample_data token?
