Internal and External Data Transfer (IETrans) for Scene Graph Generation

This is the code for ECCV 2022 (Oral) paper "Fine-Grained Scene Graph Generation with Data Transfer". Our paper get (1, 1, 2) from reviewers which is near to full marks (1, 1, 1).

Overview

alt text

Internal Transfer: transfer data from general predicate categories (e.g. on) to informative ones (e.g. riding on).
External Transfer: relabel unannoated data.

Install

Please refer to INSTALL.

Dataset

Please refer to DATASET.

Object Detector

Download Pre-trained Detector

In generally SGG tasks, the detector is pre-trained on the object bounding box annotations on training set. We directly use the pre-trained Faster R-CNN provided by Scene-Graph-Benchmark.pytorch, because our 20 category setting and their 50 category setting have the same training set.

After you download the Faster R-CNN model, please extract all the files to the directory /home/username/checkpoints/pretrained_faster_rcnn. To train your own Faster R-CNN model, please follow the next section.

The above pre-trained Faster R-CNN model achives 38.52/26.35/28.14 mAp on VG train/val/test set respectively.

Pre-train Your Own Detector

In this work, we do not modify the Faster R-CNN part. The training process can be referred to the origin code.

IETrans

All commands of training are saved in the directory cmds/. The directory of cmds looks like:

cmds/  
├── 50 
│   └── motif
│       ├── predcls
│       │   ├── lt \\ training to cope with long-tail distribution

Generally, we first train a normal supervised model, and then use this model to relabel existing dataset (IETrans).

All checkpoints can be downloaded from MODEL_ZOO.md.

Preparation

Before running the code, you need to specify the current path as environment variable SG and the experiments' root directory as EXP.

# specify current directory as SG, e.g.:
export SG=~/IETrans-SGG.pytorch
# specify experiment directory, e.g.:
export EXP=~/exps

VG-50-Training

For our pre-trained models and enhanced datasets, please refer to MODEL_ZOO.md

  1. PREDCLS
bash cmds/50/motif/predcls/predcls.sh # run a sinlge command for all things

You can also run step by step:

# train a supervised model
bash cmds/50/motif/predcls/sup/train.sh
# conduct internal transfer
bash cmds/50/motif/predcls/lt/internal/relabel.sh
# conduct external transfer
bash cmds/50/motif/predcls/lt/external/relabel.sh
# combine internal and external transferred data
bash cmds/50/motif/predcls/lt/combine/combine.sh

# train a new model
bash cmds/50/motif/predcls/lt/combine/train.sh

# train a new model using rwt
bash cmds/50/motif/predcls/lt/combine/train_rwt.sh

The key for rwt is IETRANS.RWT True and WSUPERVISE.LOSS_TYPE ce_rwt.

To evaluate a trained model.

bash cmds/50/motif/predcls/lt/combine/val.sh

Do not forget to specify the OUTPUT_PATH in val.sh as the path to the model directory you want to evaluate.

Note that the motif can replaced with other models we provide (e.g. gpsnet, vctree, and transformer).

  1. SGCLS
bash cmds/50/motif/sgcls/lt/combine/train_rwt.sh
  1. SGDET
bash cmds/50/motif/sgdet/lt/combine/train_rwt.sh

VG-1800-Training

The overall training is similar with VG-50.

  1. PREDCLS
bash cmds/1000/motif/predcls.sh
  1. SGCLS
bash cmds/1000/motif/sgcls/lt/combine/train_0.1.sh # 0.1 indicates the internal transfer percentage (k_I)
# or
bash cmds/1000/motif/sgcls/lt/combine/train_0.9.sh
  1. Evaluation

First go to the OUTPUT_PATH of your model.

cd $OUTPUT_PATH/inference/1000VG_stanford_filtered_with_attribute_test
cp $SG/tools/vg1800/eval.py ./
python eval.py # the script will output obj, predicate and rel accs.
