Model Zoo (Pretrained Models)

We provide the training logs & pretrained models in column our released trained with the improved training strategies proposed by our PointNeXt through Google Drive.

TP: Throughput (instance per second) measured using an NVIDIA Tesla V100 32GB GPU and a 32 core Intel Xeon @ 2.80GHz CPU.
