Thank you for your question! Would you mind sharing the training log? I plan to try to debug the segmentation code after my vacation (April 10th), sorry for the bugs!
log.txt Here is my log file, thank you very much
Hi! Sorry for the late reply. I have through the pipeline (data preparation + model training) again. Again, I failed to reproduce the error you encountered. I would suspect this is due to the environment. Therefore, I have updated my environment in the repository ('environment.yaml'). You may install it with conda env create -f environment.yaml
. Please let me know if the model is not working under this environment - then it would be great if you can leave your email address for me to share the data I just generated today.
Hi, thank you for this excellent work.!When I trained the Partseg model using my own dataset, I encountered a situation where the acc was very low and the iou was very high.

Hi! This could be because the zero-division returning value is 1 in IoU computation. Specifically, in our implementation we followed dgcnn: if the union of ground truth and prediction points is empty, then count part IoU as 1. By modifying 'iou=1' to 'iou=0' in line 40 in main_partseg.py, the zero-division returning value should be 0 and by then IoU will not be 'overestimated'.
For the model performance, there could be multiple reasons. Could you try to tune the hyperparameters on your dataset, e.g., decreasing the model size and the dropout rate?
Thank you for your work!The results of my run on the dataset are shown in this figure. Obviously, I have encountered a problem. I hope you can help me with the answer. Thank you very much!
