Introduction

This project is based on the code of Scene Graph Benchmark in Pytorch.

Method overview

Installation

• Clone this repo

git clone https://github.com/siml3/HL-Net.git
cd HL-Net

• Create a conda virtual environment and activate it (optional)

conda create -n hlnet -y
conda activate hlnet

• Prepare proper pytorch environment for your device.

• Install dependencies

  conda install ipython
  conda install scipy
  conda install h5py
  pip install ninja yacs cython matplotlib tqdm opencv-python-headless overrides
  
  
  git clone https://github.com/cocodataset/cocoapi.git
  cd cocoapi/PythonAPI
  python setup.py build_ext install
  cd ../../
  
  # GPU and Cuda environment is necessary for proper compilation of this repo
  git clone https://github.com/NVIDIA/apex.git
  cd apex
  python setup.py install --cuda_ext --cpp_ext
  cd ../
  

• Compile extensions and install this repo in develop mode

  python setup.py build develop
  

Dataset

Please refer to the DATASET.md

CUDA_VISIBLE_DEVICES=0,1,2,3 python -m torch.distributed.launch --master_port 10001 --nproc_per_node=4 tools/detector_pretrain_net.py --config-file "configs/e2e_relation_detector_X_101_32_8_FPN_1x.yaml" SOLVER.IMS_PER_BATCH 8 TEST.IMS_PER_BATCH 4 DTYPE "float32" SOLVER.MAX_ITER 50000 SOLVER.STEPS "(30000, 45000)" SOLVER.VAL_PERIOD 2000 SOLVER.CHECKPOINT_PERIOD 2000 MODEL.RELATION_ON False SOLVER.PRE_VAL False OUTPUT_DIR /path/to/output 

Training on Scene Graph Generation

The training scripts are available in the folder scripts

If you have multi gpus, try the command as the follows for SGCLS:

# four cards
PYTHONPATH=$PWD CUDA_VISIBLE_DEVICES=0,1,2,3 python -m torch.distributed.launch --master_port 10022 --nproc_per_node=4 tools/relation_train_net.py --config-file "configs/e2e_relation_X_101_32_8_FPN_1x.yaml" MODEL.ROI_RELATION_HEAD.USE_GT_BOX True MODEL.ROI_RELATION_HEAD.USE_GT_OBJECT_LABEL False MODEL.PRETRAINED_DETECTOR_CKPT checkpoints/pretrained_faster_rcnn/model_final.pth OUTPUT_DIR "exp/HL-Net-sgcls" SOLVER.IMS_PER_BATCH 12 TEST.IMS_PER_BATCH 4 DTYPE "float16" SOLVER.PRE_VAL True MODEL.ROI_RELATION_HEAD.PREDICTOR HLNetPredictor MODEL.ROI_RELATION_HEAD.MP_LAYER_NUM 5 SOLVER.BASE_LR 0.0025 GLOVE_DIR glove MODEL.ROI_RELATION_HEAD.PPR_ALPHA -0.5

Testing

gpu_id=0,1
port=10086
gpu_num=2
output_dir="home/XXXX/exp/.."

PYTHONPATH=$PWD CUDA_VISIBLE_DEVICES=${gpu_id} python -m torch.distributed.launch --master_port ${port} --nproc_per_node=${gpu_num} tools/relation_test_net.py --config-file "${output_dir}/config.yml" MODEL.ROI_RELATION_HEAD.USE_GT_BOX True MODEL.ROI_RELATION_HEAD.USE_GT_OBJECT_LABEL False OUTPUT_DIR "${output_dir}" TEST.IMS_PER_BATCH ${gpu_num} DTYPE "float16" GLOVE_DIR glove
