Train Your Model

1.Before Run You Need:

1. cd ./lib

   Change gpu_id in make.sh and setup.py.
   Detially, you need modify parameter setting in line 5, 12 and 19 in make.sh and line 143 in setup.py where include key words '-arch=' depend on your gpu model.(select appropriate architecture described in table below)

   sh make.sh

   GPU model	Architecture
   TitanX (Maxwell/Pascal)	sm_52
   GTX 960M	sm_50
   GTX 108 (Ti)	sm_61
   Grid K520 (AWS g2.2xlarge)	sm_30
   Tesla K80 (AWS p2.xlarge)	sm_37

2. cd ../

   mkdir ./data

   mkdir ./data/pretrained_model

   download pre-trained weights in ./data/pretrained_model

3. run train.py

2.How to use?

Note: decentralization in preprocesing is based on BGR channels, so you must guarantee your pre-trained model is trained on the same channel set if you use transfer learning

For example:

VGG: CUDA_VISIBLE_DEVICES=1 python train.py --net='vgg16' --tag=vgg16 --iters=70000 --cfg='./experiments/cfgs/vgg16.yml' --weight='./data/pretrained_model/vgg16_caffe.pth'

CUDA_VISIBLE_DEVICES=2 python test.py --net='vgg16' --tag=vgg16 --model=60000 --cfg='./experiments/cfgs/vgg16.yml' --model_path='voc_2007_trainval/vgg16/vgg16_faster_rcnn' --imdb='voc_2007_test' --comp

ResNet:

CUDA_VISIBLE_DEVICES=2 python train.py --net='res18' --tag=res18 --iters=70000 --cfg='./experiments/cfgs/res18.yml' --weight='./data/pretrained_model/Resnet18_imagenet.pth'

CUDA_VISIBLE_DEVICES=3 python train.py --net='res50' --tag=res50 --iters=70000 --cfg='./experiments/cfgs/res50.yml' --weight='./data/pretrained_model/Resnet50_imagenet.pth'

CUDA_VISIBLE_DEVICES=7 python train.py --net='res101' --tag=res101 --iters=80000 --cfg='./experiments/cfgs/res101.yml' --weight='./data/pretrained_model/resnet101_caffe.pth'

CUDA_VISIBLE_DEVICES=6 python test.py --net='res101' --tag=res101_1 --cfg='./experiments/cfgs/res101.yml' --model=70000 --model_path='voc_2007_trainval/res101_1' --imdb='voc_2007_test' --comp
