Model checkpoint

May I ask when will release the model checkpoint? Thanks.

You used model.mat to generate gt_file, but did not mention anywhere how to get it

Is that possible to get your generated dataset?

how use the render to create pcd from dataset of ShapeNetv1 ?

it is not like a part model of point cloud model, but just like a picture in a zoom.

Could you give more details about how to get correspoing ground truths by sampling from CAD models

TF_ops的.sh文件无法保证有效

我的python是3.6，tensorflow是1.12.0，cuda是10.0，在运行nn_distance_comple.sh后，
检查

后再运行train.py，出现问题：
