# dgcnn

This is an implementation of 3D point cloud semantic segmentation for [Dynamic Graph Convolutional Neural Network](https://arxiv.org/abs/1801.07829). The number of edge convolution layers, fully connected layers, and number of filters per each layer are all configurable. The implementation includes a few variations such as residual unit (edge convolution with identity mapping), with or without fully connected layers, etc.. Experimental results on DeepLearnPhysics open data set will be made available.

### Requirements

* `tensorflow >= v1.3`

* `numpy >= 1.13` 

* Optional requirements for IO include `h5py`, `larcv`

### Help

An executable script can be found at `bin/dgcnn.py`. The script takes `train` or `inference` arguments. Try `--help` to list available arguments:

```

bin/dgcnn.py train --help

```

### How to run

Below is an example of how to train the network using `mydata.hdf5` data file with `hdf5` format, 4 GPUs with batch size 24 and mini-batch size of 6, store snapshot every 500 iterations, print out info (loss,accuracy,etc) every 10 iterations, and store tensorboard summary every 50 iterations.

```

bin/dgcnn.py train --gpus 0,1,2,3 -bs 24 -mbs 6 -chks 500 -rs 10 -ss 50 -if mydata.hdf5 -io h5

```

See `--help` to find more flags and a descipriton for arguments.
