### (1) Setup
This code has been tested with Python 3.5, Tensorflow 1.11, CUDA 9.0 and cuDNN 7.4.1 on Ubuntu 16.04/Ubuntu 18.04.
- Clone the repository
```
git clone --depth=1 https://github.com/QingyongHu/SQN && cd SQN
```
- Setup python environment
```
conda create -n sqn python=3.5
source activate sqn
pip install -r helper_requirements.txt
sh compile_op.sh
```
### (2) Training (Semantic3D as example)
First, follow the RandLA-Net [instruction](https://github.com/QingyongHu/RandLA-Net) to prepare the dataset, and then
manually change the
dataset [path](https://github.com/QingyongHu/SQN/blob/f75eb51532a5319c0da5320c20f58fbe5cb3bbcd/main_Semantic3D.py#L17) here.
- Start training with weakly supervised setting:
```
python main_Semantic3D.py --mode train --gpu 0 --labeled_point 0.1%
```
- Evaluation:
```
python main_Semantic3D.py --mode test --gpu 0 --labeled_point 0.1%
```
Quantitative results achieved by our SQN:
