This is an implementation of Deformable-DETR

Deformable-DETR: Deformable Transformers for End-to-End Object Detection

Deformable-DETR

This an implementation of Deformable-DETR. Codes are based on DETR project. My code is inspired by his/her work. Many thanks.

Preparation

For DETR stuffs, etc. data preparation, evaluation, and others , please refer to DETR.

Training

My machine is equipped with two GTX 2080TIs. Below is the training script for DDP training.

bash train.sh

For single gpu training, try the code below

python main.py
--output_dir my_output \
--coco_path ~/dev/data/coco \
--lr 0.0002 \
--lr_backbone 0.00001 \
--num_queries 300 \
--batch_size 1 \
--enc_layers 6 \
--dec_layers 6 \
--no_aux_loss \
--amp

If you do not need AMP, just remove this flag.
