in ./train/sdf_train.py
line 417/418 and line 427/428
why output "batch_data['sdf_pt_rot'][bid,:,:]" twice, one called 'pred.obj' and other called 'gt.obj'? they are the same.
and during training, the batch_data['sdf_pt_rot'] also equal to batch_data['sdf_pt'],
there are no 3D obj produced during sdf_train right? just 1D pred_sdf value at shape [B, 2048 , 1]， right？
i just operated to sdf_train , and haven't run 'inference sdf and create mesh objects'
