Scene Graph Benchmark in PyTorch 1.7
This project is based on maskrcnn-benchmark
Highlights
- Upgrad to pytorch 1.7
- Multi-GPU training and inference
- Batched inference: can perform inference using multiple images per batch per GPU.

- Provides bounding box level and relation level feature extraction functionalities
- Provides large detector backbones (ResNxt152)
Installation
Check INSTALL.md for installation instructions.
Model Zoo and Baselines
Pre-trained models can be found in SCENE_GRAPH_MODEL_ZOO.md
Visualization and Demo
We provide a helper class to simplify writing inference pipelines using pre-trained models (Currently only support objects and attributes). Here is how we would do it. Run the following commands:

Perform training
For the following examples to work, you need to first install this repo.
You will also need to download the dataset. Datasets can be downloaded by azcopy with following command:
path/to/azcopy copy 'https://penzhanwu2.blob.core.windows.net/sgg/sgg_benchmark/datasets/TASK_NAME' <target folder> --recursive
TASK_NAME could be visualgenome, openimages_v5c.
We recommend to symlink the path to the dataset to datasets/ as follows
# symlink the dataset
cd ~/github/maskrcnn-benchmark
mkdir -p datasets/openimages_v5c/
ln -s /vrd datasets/openimages_v5c/vrd
You can also prepare your own datasets.
Follow tsv dataset creation instructions tools/mini_tsv/README.md
Single GPU training
python tools/train_sg_net.py --config-file "/path/to/config/file.yaml"
This should work out of the box and is very similar to what we should do for multi-GPU training. But the drawback is that it will use much more GPU memory. The reason is that we set in the configuration files a global batch size that is divided over the number of GPUs. So if we only have a single GPU, this means that the batch size for that GPU will be 4x larger, which might lead to out-of-memory errors.
Multi-GPU training
We use internally torch.distributed.launch in order to launch multi-gpu training. This utility function from PyTorch spawns as many Python processes as the number of GPUs we want to use, and each Python process will only use a single GPU.
export NGPUS=4
python -m torch.distributed.launch --nproc_per_node=$NGPUS tools/train_sg_net.py --config-file "path/to/config/file.yaml"
Evaluation
You can test your model directly on single or multiple gpus. To evaluate relations, one needs to output "relation_scores_all" in the TSV_SAVE_SUBSET. Here are a few example command line for evaluating on 4 GPUS:
export NGPUS=4
python -m torch.distributed.launch --nproc_per_node=$NGPUS tools/test_sg_net.py --config-file CONFIG_FILE_PATH
# vg IMP evaluation
python -m torch.distributed.launch --nproc_per_node=$NGPUS tools/test_sg_net.py --config-file sgg_configs/vg_vrd/rel_danfeiX_FPN50_imp.yaml
# vg MSDN evaluation
python -m torch.distributed.launch --nproc_per_node=$NGPUS tools/test_sg_net.py --config-file sgg_configs/vg_vrd/rel_danfeiX_FPN50_msdn.yaml

python -m torch.distributed.launch --nproc_per_node=$NGPUS tools/test_sg_net.py --config-file sgg_configs/oi_vrd/R152FPN_msdn_bias_oi.yaml
# oi neural motif evaluation
python -m torch.distributed.launch --nproc_per_node=$NGPUS tools/test_sg_net.py --config-file sgg_configs/oi_vrd/R152FPN_motif_oi.yaml
# oi GRCNN evaluation
python -m torch.distributed.launch --nproc_per_node=$NGPUS tools/test_sg_net.py --config-file sgg_configs/oi_vrd/R152FPN_grcnn_oi.yaml
# oi RelDN evaluation
python -m torch.distributed.launch --nproc_per_node=$NGPUS tools/test_sg_net.py --config-file sgg_configs/vrd/R152FPN_vrd_reldn.yaml
To evaluate in sgcls mode:
export NGPUS=4
python -m torch.distributed.launch --nproc_per_node=$NGPUS tools/test_sg_net.py --config-file CONFIG_FILE_PATH MODEL.ROI_BOX_HEAD.FORCE_BOXES True MODEL.ROI_RELATION_HEAD.MODE "sgcls"
To evaluate in predcls mode:
export NGPUS=4
python -m torch.distributed.launch --nproc_per_node=$NGPUS tools/test_sg_net.py --config-file CONFIG_FILE_PATH MODEL.ROI_RELATION_HEAD.MODE "predcls"
To evaluate with ground truth bbox and ground truth pairs:
export NGPUS=4
python -m torch.distributed.launch --nproc_per_node=$NGPUS tools/test_sg_net.py --config-file CONFIG_FILE_PATH MODEL.ROI_RELATION_HEAD.FORCE_RELATIONS True
Abstractions
For more information on some of the main abstractions in our implementation, see ABSTRACTIONS.md.
Adding your own dataset
This implementation adds support for TSV style datasets. But adding support for training on a new dataset can be done as follows:
from maskrcnn_benchmark.data.datasets.relation_tsv import RelationTSVDataset
class MyDataset(RelationTSVDataset):
def __init__(self, yaml_file, extra_fields=(), transforms=None,
is_load_label=True, **kwargs):
super(MyDataset, self).__init__(yaml_file, extra_fields, transforms, is_load_label, **kwargs)
def your_own_function(self, idx, call=False):
# you can overwrite function or add your own functions this way
pass
That's it. You can also add extra fields to the boxlist, such as segmentation masks (using structures.segmentation_mask.SegmentationMask), or even your own instance type.
For a full example of how the VGTSVDataset is implemented, check maskrcnn_benchmark/data/datasets/vg_tsv.py.
Once you have created your dataset, it needs to be added in a couple of places:
maskrcnn_benchmark/data/datasets/__init__.py: add it to__all__maskrcnn_benchmark/data/datasets/utils/config_args.py: add it's name as an option totsv_dataset_name
Adding your own evaluation
To enable your dataset for testing, add a corresponding if statement in maskrcnn_benchmark/data/datasets/evaluation/__init__.py:
if isinstance(dataset, datasets.MyDataset):
return your_evaluation(**args)
VinVL Feature extraction
The output feature will be encoded as base64
# extract vision features with VinVL object-attribute detection model
# pretrained models at https://penzhanwu2.blob.core.windows.net/sgg/sgg_benchmark/vinvl_model_zoo/vinvl_vg_x152c4.pth
# the associated labelmap at https://penzhanwu2.blob.core.windows.net/sgg/sgg_benchmark/vinvl_model_zoo/VG-SGG-dicts-vgoi6-clipped.json
python tools/test_sg_net.py --config-file sgg_configs/vgattr/vinvl_x152c4.yaml TEST.IMS_PER_BATCH 2 MODEL.WEIGHT models/vinvl/vinvl_vg_x152c4.pth MODEL.ROI_HEADS.NMS_FILTER 1 MODEL.ROI_HEADS.SCORE_THRESH 0.2 DATA_DIR "../maskrcnn-benchmark-1/datasets1" TEST.IGNORE_BOX_REGRESSION True MODEL.ATTRIBUTE_ON True
To extract relation features (union bounding box's feature), in yaml file, set TEST.OUTPUT_RELATION_FEATURE to True, add relation_feature in TEST.TSV_SAVE_SUBSET.
To extract bounding box features, in yaml file, set TEST.OUTPUT_FEATURE to True, add feature in TEST.TSV_SAVE_SUBSET.
