Thank you very much for your excellent work。 How can I get the number of points for each point cloud in a batch? The batch_dict contains the points of all the point clouds in a batch. What do I do if I want to get a point cloud in a batch? Looking forward to your reply！

Please refer this line. The first dim of points is batch id.
