[Semantic Segmentation] - Problem when re-training Semantic segmentation, Accuracy decrease with parameter default?

[vanloctc]

Hi @charlesq34,

I'm really grateful when you public this source for me to have a chance to learn. I'm trying to re-training PointNet Semantic Segmentation but seems to be the training process met overfitting/underfitting with the 10th epoch. I still try for researching the cause but I think you can know the more cleary result. This is a summary result:

Hello @vanloctc, have you found any feasible solution for your case? I have been facing similar issue with my custom dataset.
