Baseline

SOTA

Note:

• Single GPU training: SAVE_WEIGHTS_INTE = iter_epoch * 1 (DOTA1.0: iter_epoch=27000, DOTA1.5: iter_epoch=32000, DOTA2.0: iter_epoch=40000)
• Multi-GPU training (better): SAVE_WEIGHTS_INTE = iter_epoch * 2

pip install -r requirements.txt
pip install -v -e .  # or "python setup.py develop"

Or, you can simply install AlphaRotate with the following command:

pip install alpharotate

docker images: yangxue2docker/yx-tf-det:tensorflow1.13.1-cuda10-gpu-py3

Note: For 30xx series graphics cards, I recommend this blog to install tf1.xx, or download image from tensorflow-release-notes according to your development environment, e.g. nvcr.io/nvidia/tensorflow:20.11-tf1-py3

Download a pretrain weight you need from the following three options, and then put it to $PATH_ROOT/dataloader/pretrained_weights.

1. MxNet pretrain weights (recommend in this repo, default in NET_NAME): resnet_v1d, resnet_v1b, refer to gluon2TF.

• Baidu Drive (5ht9)
• Google Drive

2. Tensorflow pretrain weights: resnet50_v1, resnet101_v1, resnet152_v1, efficientnet, mobilenet_v2, darknet53 (Baidu Drive (1jg2), Google Drive).
3. Pytorch pretrain weights, refer to pretrain_zoo.py and Others.

• Baidu Drive (oofm)
• Google Drive

1. Please download trained models by this project, then put them to $PATH_ROOT/output/pretained_weights.

1. If you want to train your own dataset, please note:

   (1) Select the detector and dataset you want to use, and mark them as #DETECTOR and #DATASET (such as #DETECTOR=retinanet and #DATASET=DOTA)
   (2) Modify parameters (such as CLASS_NUM, DATASET_NAME, VERSION, etc.) in $PATH_ROOT/libs/configs/#DATASET/#DETECTOR/cfgs_xxx.py
   (3) Copy $PATH_ROOT/libs/configs/#DATASET/#DETECTOR/cfgs_xxx.py to $PATH_ROOT/libs/configs/cfgs.py
   (4) Add category information in $PATH_ROOT/libs/label_name_dict/label_dict.py     
   (5) Add data_name to $PATH_ROOT/dataloader/dataset/read_tfrecord.py  
   

2. Make tfrecord
   If image is very large (such as DOTA dataset), the image needs to be cropped. Take DOTA dataset as a example:

   cd $PATH_ROOT/dataloader/dataset/DOTA
   python data_crop.py
   

   If image does not need to be cropped, just convert the annotation file into xml format, refer to example.xml.

   cd $PATH_ROOT/dataloader/dataset/  
   python convert_data_to_tfrecord.py --root_dir='/PATH/TO/DOTA/' 
                                      --xml_dir='labeltxt'
                                      --image_dir='images'
                                      --save_name='train' 
                                      --img_format='.png' 
                                      --dataset='DOTA'
   

3. Start training

   cd $PATH_ROOT/tools/#DETECTOR
   python train.py
   

1. For large-scale image, take DOTA dataset as a example (the output file or visualization is in $PATH_ROOT/tools/#DETECTOR/test_dota/VERSION):

   cd $PATH_ROOT/tools/#DETECTOR
   python test_dota.py --test_dir='/PATH/TO/IMAGES/'  
                       --gpus=0,1,2,3,4,5,6,7  
                       -ms (multi-scale testing, optional)
                       -s (visualization, optional)
                       -cn (use cpu nms, slightly better <1% than gpu nms but slower, optional)
   
   or (recommend in this repo, better than multi-scale testing)
   
   python test_dota_sota.py --test_dir='/PATH/TO/IMAGES/'  
                            --gpus=0,1,2,3,4,5,6,7  
                            -s (visualization, optional)
                            -cn (use cpu nms, slightly better <1% than gpu nms but slower, optional)
   

   Notice: In order to set the breakpoint conveniently, the read and write mode of the file is' a+'. If the model of the same #VERSION needs to be tested again, the original test results need to be deleted.

2. For small-scale image, take HRSC2016 dataset as a example:

   cd $PATH_ROOT/tools/#DETECTOR
   python test_hrsc2016.py --test_dir='/PATH/TO/IMAGES/'  
                           --gpu=0
                           --image_ext='bmp'
                           --test_annotation_path='/PATH/TO/ANNOTATIONS'
                           -s (visualization, optional)
   

cd $PATH_ROOT/output/summary
tensorboard --logdir=.
