How to test the test set of stpls3d

[WS517]

Hello and thanks for your great work. I have observed that you have created a new file in ISBNet/dataset/stpls3d
/prepare_data_inst_instance_stpls3d.py file did not divide the test set for the stpls3d dataset, I would like to know how to test it against the stpls3d unlabeled test data which has only 6 columns of data in xyzrgb, I look forward to your reply, thank you very much!
