It can be seen from the tensorboard that the classification ability of the model is particularly poor and the score is relatively low. There may be a problem with the focal loss, and I am still looking for the cause.
This is a tensorflow re-implementation of FCOS: Fully Convolutional One-Stage Object Detection, and completed by YangXue.
| Model | Backbone | Train Schedule | GPU | Image/GPU | FP16 | Box AP |
|---|---|---|---|---|---|---|
| FCOS (ours) | R50v1 | 1X | 8X GeForce RTX 2080 Ti | 2 | no | Debugging |
1、python3.5 (anaconda recommend)
2、cuda9.0
3、opencv(cv2)
4、tfplot
5、tensorflow >= 1.12
1、Please download resnet50_v1, resnet101_v1 pre-trained models on Imagenet, put it to data/pretrained_weights.
2、Or you can choose to use a better backbone, refer to gluon2TF. Pretrain Model Link, password: q4jg.
Select a configuration file in the folder ($PATH_ROOT/libs/configs/) and copy its contents into cfgs.py, then download the corresponding weights.
cd $PATH_ROOT/libs/box_utils/cython_utils
python setup.py build_ext --inplace
cd $PATH_ROOT/libs/box_utils/nms
python setup.py build_ext --inplace
1、If you want to train your own data, please note:
(1) Modify parameters (such as CLASS_NUM, DATASET_NAME, VERSION, etc.) in $PATH_ROOT/libs/configs/cfgs.py
(2) Add category information in $PATH_ROOT/libs/label_name_dict/lable_dict.py
(3) Add data_name to line 76 of $PATH_ROOT/data/io/read_tfrecord.py
2、make tfrecord
cd $PATH_ROOT/data/io/
python convert_data_to_tfrecord_coco.py --VOC_dir='/PATH/TO/JSON/FILE/'
--save_name='train'
--dataset='coco'
3、multi-gpu train
cd $PATH_ROOT/tools
python multi_gpu_train.py
cd $PATH_ROOT/tools
python eval_coco.py --eval_data='/PATH/TO/IMAGES/'
--eval_gt='/PATH/TO/TEST/ANNOTATION/'
--GPU='0'
cd $PATH_ROOT/output/summary
tensorboard --logdir=.
