The instance segmentation accuracy of a certain category is always 0？

Hello, thank you very much for sharing. When I ran my own dataset for instance segmentation, I encountered the following problem: the instance segmentation of leaf is 0, I would like to ask you how to solve this problem?

For custom dataset, I suggest to turning the hyper-parameter that is related to point cloud density, such as scale, radius, mean active. You can check it via comparing scannet and stpls3d config, then turn your hyper-parameters appropreately.

你好，非常感谢你的分享，我在跑自己的数据集做实例分割的时候，遇到了如下问题：leaf的实例分割为0，请问你这个问题是怎么解决的？

Hello, can I learn from you how to train my own dataset? Thank you for your reply
