Dear Professor Li:
Thanks for your great work and the open-source code.

I want to know why the keypoints visualization results I obtained using the model 5000-64-k1k9-3d (modelnet40 dataset) differ significantly from your visualization results in the paper. May I ask where the problem may be.

My visualization results are as follows:

The visualization results of modelnet40 in your paper are as follows:

I checked the parameters and they were all set according to the paper. Is it necessary to set the radius of nms to another value since it is 0?
