How can I use with custom dataset

[RyanPham19092002]

I have 6 custom images for the input, how can I use it for visualization. I changed the dataroot in vis_frame.py and had an error

nusc = NuScenes(version='v1.0-trainval', dataroot=data_path, verbose=True)
File "/opt/conda/lib/python3.10/site-packages/nuscenes/nuscenes.py", line 62, in init
assert osp.exists(self.table_root), 'Database version not found: {}'.format(self.table_root)
AssertionError: Database version not found: /root/Town05/ClearNoon/vehicle.tesla.invisible/spawn_point_10/step_41/nuscenes/transforms/input_images/v1.0-trainval

Please help me, thanks a lot!
