About the performance

Thanks for your owesome work!

Thanks for your opened code, it's very helpful for me!

I reproduced the released code on the S3DIS dataset, but I only got 0.552240 test iou in the training process, which is a certain gap from any version (v1-v4) of the paper. What is the reason? Here is my training log:
