loss doesn't decrease about openscene HOT 3 CLOSED

Emmmm that is strange. Could you try training with just 1 scene instead of the entire dataset, and see if your network is able to overfit this scene (i.e., getting similar results to 2D fusion results like miou=0.2391)?

Thanks for the reply. I found a bug in my 3d data processing code. It can produce reasonable performance now.

By the way, does batch size affect the performance a lot? When I reproduce the results for Scannet, I set the batch_size=4 to fit in the 24GB GPU. But the miou of 3D distillation model is around 42 (46 in the table 4 of paper).

Sorry for the late reply, yes, batch_size makes some differences, so maybe you can consider using multi-GPU training to increase the batch_size?
