the log of train_completion.py

Hi @hansen7 , Thanks for sharing this great work with us. I have a question regarding the output log during pretraining. The detail is here. The question is, it seems that the loss did not drop too much or its range is varied from 0.03 to 0.04. Did this happen to your pretraining as well? But visually, I could see some improvements in the plots folder. Best regards

Thank you, @zshyang. In my experience, the pretraining loss also reached saturation quickly.

Regarding the scenario where better visualizations with a slightly increased loss, I believe this is due to the Chamber Distance loss being poorly calibrated. It does not accurately represent the true quality of the generated point clouds.
