The repository contains the training code of MDef-DETR. The paper is availe on arxiv.

pip install -r requirements.txt

Distributed training is available via Slurm and submitit:

pip install submitit

The config file for pretraining is configs/pretrain.json and looks like:

{
    "combine_datasets": ["flickr", "mixed"],
    "combine_datasets_val": ["flickr", "gqa", "refexp"],
    "coco_path": "",
    "vg_img_path": "",
    "flickr_img_path": "",
    "refexp_ann_path": "annotations/",
    "flickr_ann_path": "annotations/",
    "gqa_ann_path": "annotations/",
    "refexp_dataset_name": "all",
    "GT_type": "separate",
    "flickr_dataset_path": ""
}

• Download the original Flickr30k image dataset from : Flickr30K webpage and update the flickr_img_path to the folder containing the images.
• Download the original Flickr30k entities annotations from: Flickr30k annotations and update the flickr_dataset_path to the folder with annotations.
• Download the gqa images at GQA images and update vg_img_path to point to the folder containing the images.
• Download COCO images Coco train2014. Update the coco_path to the folder containing the downloaded images.
• Download pre-processed annotations that are converted to coco format (all datasets present in the same zip folder for MDETR annotations): Pre-processed annotations and update the flickr_ann_path, gqa_ann_path and refexp_ann_path to this folder with pre-processed annotations.

Alternatively, you can download the preprocessed data from the link as a single zip file and extract it under data directory.

This command will reproduce the training of the resnet 101.

python run_with_submitit.py --dataset_config configs/pretrain.json  --ngpus 8 --nodes 4 --ema --epochs 20 --lr_drop 16
