CenterNet-better-plus

This repo is implemented based on detectron2 and CenterNet-better

Requirements

• Python >= 3.6
• PyTorch >= 1.4
• torchvision that matches the PyTorch installation.
• OpenCV
• pycocotools

pip install cython; pip install 'git+https://github.com/cocodataset/cocoapi.git#subdirectory=PythonAPI'

• GCC >= 4.9

gcc --version

• detectron2

pip install -U 'git+https://github.com/facebookresearch/detectron2.git'

Training

python train_net.py --num-gpus 8 --config-file configs/centernet_r_18_C4_1x.yaml

Testing and Evaluation

python train_net.py --num-gpus 8 --config-file configs/centernet_r_18_C4_1x.yaml --eval-only MODEL.WEIGHTS model_0007999.pth

Performance

This repo use less training time to get a better performance, it nearly spend half training time and get 1~2 pts higher mAP compared with the old repo. Here is the table of performance.

Backbone ResNet-50

Code	mAP
ours
centernet-better	35.1

Backbone ResNet-18

Code	mAP
ours	29.7
centernet-better	29.8

What's comming

• Support DLA backbone
• Support Hourglass backbone
• Support KeyPoints dataset
