1. Python3 (with necessary common libraries such as numpy, scipy, etc.)
2. TensorFlow(1.10 or other)
3. You can prepare your data in *.npy file or other,here I use .npy file:
   • .npy file include : x y z label.
   • I'm doing semantic segmentation,so I made some changes to the data.

python ../data/pre_data.py

python train.py

python test.py
