Hit-Detector Code Base

Implementation of our CVPR2020 paper Hit-Detector: Hierarchical Trinity Architecture Search for Object Detection

We released the searched Hit-Detector Architecture.

Environments

• Python 3.6
• Pytorch>=1.1.0
• Torchvision == 0.3.0

You can directly run the code sh env.sh to setup the running environment. We use 8 GPUs (32GB V100) to train our detector, you can adjust the batch size in configs by yourselves.
