Large-scale Visual Relationship Understanding

alt text

Example results from the VG80K dataset.

This is the Caffe2 implementation for Large-scale Visual Relationship Understanding, AAAI2019.

This code is for the VG80K dataset only. For results on VG200 and VRD please refer to the PyTorch implementation.

Note: In this repo we use ground-truth boxes during testing, so there is no object detection module involved in this repo.

Caffe2

To install Caffe2 with CUDA support, follow the installation instructions from the Caffe2 website. If you already have Caffe2 installed, make sure to update your Caffe2 to a version that includes the Detectron module.

Please ensure that your Caffe2 installation was successful before proceeding by running the following commands and checking their output as directed in the comments.

# To check if Caffe2 build was successful
python2 -c 'from caffe2.python import core' 2>/dev/null && echo "Success" || echo "Failure"

# To check if Caffe2 GPU build was successful
# This must print a number > 0 in order to use Detectron
python2 -c 'from caffe2.python import workspace; print(workspace.NumCudaDevices())'

If the caffe2 Python package is not found, you likely need to adjust your PYTHONPATH environment variable to include its location (/path/to/caffe2/build, where build is the Caffe2 CMake build directory).

Other Dependencies

Install Python dependencies:

pip install numpy>=1.13 pyyaml>=3.12 matplotlib opencv-python>=3.2 setuptools Cython mock scipy

Large-scale-VRD

Clone the Large-scale-VRD repository:

# Large-scale-VRD=/path/to/clone/Large-scale-VRD
git clone https://github.com/fairinternal/VRD $Large-scale-VRD

Set up Python modules:

cd $Large-scale-VRD/lib && make

Annotations

Download VG annotation files from here. Put the zip file under $Large-scale-VRD and unzip it. You should see a datasets folder unzipped there.

Datasets

Download VG80K images from here. Unzip all images into $Large-scale-VRD/datasets/large_scale_VRD/Visual_Genome/images.

Pretrained Embedding Models

Download pretrained embeddings from here. Put the zip file under $Large-scale-VRD/datasets/large_scale_VRD and unzip it. You should see a "label_embeddings" folder and a "models" folders there.

Our Trained Models

You can download our trained models from here. Put the zip file under $Large-scale-VRD and unzip it. You should see a checkpoints folder unzipped there.

Training

To train VG80K with 8 GPU, run:

python tools/train_net_rel.py --cfg configs/vg/VG_wiki_and_relco_VGG16_softmaxed_triplet_2_lan_layers_8gpu.yaml

Testing

To test VG80K with 8 GPU, run:

python tools/test_net_rel.py --cfg configs/vg/VG_wiki_and_relco_VGG16_softmaxed_triplet_2_lan_layers_8gpu.yaml
