rgbd_graspnet

Implementation for ICRA 2021 paper RGB Matters: Learning 7-DoF Grasp Poses on Monocular RGBD Images.

Project Website https://graspnet.net/publications.html

Installation

git clone https://github.com/GouMinghao/rgb_matters
cd rgb_matters

# virtualenv, conda or docker are strongly suggested.
python3 -m pip install -r requirements.txt

Download the GraspNet dataset

Download and setup following the official website.

Generate label

Modify the values in constant.py to your own.
Run gen_labels.py

# Around 260G space is needed if all the labels are generated.
python3 gen_labels.py

Check if all labels are generated.

python3 check_label_integrity.py

No errors will be presented if all labels exist.

Visualize the generated labels.

python3 vis_label.py

Generate normals (optional)

If you want to use the normal modality, you should generate normals by running the following scripts.

# Around 130G space is needed if all the normals are generated.
python3 gen_normals.py

Training

Training on a sinlge GPU

cd rgb_matters

# bash train.sh [config name] [GPU Ids] [ddp port](default=12345)
bash train.sh 0 rs_rs_no_norm 12345 # training with rs_rs_no_norm.yaml config with GPU 0.

Training on multiple GPUs

cd rgb_matters

# bash train.sh [config name] [GPU Ids] [ddp port](default=12345)
bash train.sh 1,2 rs_rs_no_norm  # training with rs_rs_no_norm.yaml config with GPU 1 and 2.

FAQ

Q1: Can I train on CPU.

A1: We don't support training on CPU, you can modify the code to train on it. However, it is not suggested.

Q2: CUDA out of memory error.

A2: Try to reduce the batch size in config file.
