mx-pointnet(in progress)

This repository contains a MXNet implementation for the Pointnet. The official implementation is avaliable here.

Note: Only support point cloud classification Currently.

Requirements and Dependencies

• Install MXNet(https://github.com/apache/incubator-mxnet) on a machine with CUDA GPU
• Install CUDNN v5 or v6
• Install h5py for python

Train and Test

• Modify config/cfg.py by your setting
• python train.py
• python test.py
