Detectron with VoVNet(CVPRW'19) backbone networks
Detectron with VoVNet(CVPRW'19) Backbone Networks
This repository contains Detectron with VoVNet (CVPRW'19) Backbone Networks. This code based on pytorch imeplementation of Detectron (maskrcnn-benchmark)
Highlights
- Memory efficient
- Better performance, especially for small objects
- Faster speed
Comparison with ResNet backbones
- 2x schedule
- same hyperparameters
- same training protocols ( max epoch, learning rate schedule, etc)
- NOT multi-scale training augmentation
- 8 x TITAN Xp GPU
- pytorch1.1
- CUDA v9
- cuDNN v7.2
Note
'*' indicates ResNeXt models from Detectron official caffe2 page.

ImageNet pretrained weight
Installation
Check INSTALL.md for installation instructions which is orginate from maskrcnn-benchmark
Training
Follow the instructions maskrcnn-benchmark guides
For example,
export NGPUS=8
python -m torch.distributed.launch --nproc_per_node=$NGPUS tools/train_net.py --config-file "configs/vovnet/e2e_faster_rcnn_V_39_FPN_2x.yaml"
Evaluation
Follow the instruction
First of all, you have to download the weight file you want to inference.
For examaple,
