Usage

Requirements

• Ubuntu 16.04
• Anaconda3 with python=3.6
• Pytorch=1.9.0
• mmdetection=2.16.0+fe46ffe
• mmcv=1.3.9
• wandb=0.10.31

Notes

• We use wandb for visualization, if you don't want to use it, just comment line 276-289 in configs/soft_teacher/base.py.

Installation

make install

Data Preparation

• Download the COCO dataset
• Execute the following command to generate data set splits:

# YOUR_DATA should be a directory contains coco dataset.
# For eg.:
# YOUR_DATA/
#  coco/
#     train2017/
#     val2017/
#     unlabeled2017/
#     annotations/ 
ln -s ${YOUR_DATA} data
bash tools/dataset/prepare_coco_data.sh conduct

Training

• To train model on the partial labeled data setting:

# JOB_TYPE: 'baseline' or 'semi', decide which kind of job to run
# PERCENT_LABELED_DATA: 1, 5, 10. The ratio of labeled coco data in whole training dataset.
# GPU_NUM: number of gpus to run the job
for FOLD in 1 2 3 4 5;
do
  bash tools/dist_train_partially.sh <JOB_TYPE> ${FOLD} <PERCENT_LABELED_DATA> <GPU_NUM>
done

For example, we could run the following scripts to train our model on 10% labeled data with 8 GPUs:

for FOLD in 1 2 3 4 5;
do
  bash tools/dist_train_partially.sh semi ${FOLD} 10 8
done

• To train model on the full labeled data setting:

bash tools/dist_train.sh <CONFIG_FILE_PATH> <NUM_GPUS>

For example, to train ours R50 model with 8 GPUs:

bash tools/dist_train.sh configs/soft_teacher/soft_teacher_faster_rcnn_r50_caffe_fpn_coco_full_720k.py 8

Inference

bash tools/dist_test.sh <CONFIG_FILE_PATH> <CHECKPOINT_PATH> <NUM_GPUS> --eval bbox --cfg-options model.test_cfg.rcnn.score_thr=<THR>
