Run inference on your own pictures.

• Prepare checkpoint:

  • Download our baseline model (Google Drive, Tsinghua Cloud, backbone: resnet101) or use your own model.
  • Specify the checkpoints file path params.ckpt in file multipose_test.py.
  • Specify the pictures file path testdata_dir and results file path testresult_dir in file multipose_test.py.

• Run:

python ./evaluate/multipose_test.py  # inference on your own pictures
python ./evaluate/multipose_coco_eval.py  # COCO evaluation

Result

• mAP (baseline checkpoint, temporarily)

Requirements

Prerequisites

• Disable cudnn for batch_norm: (See: @Microsoft / human-pose-estimation.pytorch#installation)

# PYTORCH=/path/to/pytorch
# for pytorch v0.4.0
sed -i "1194s/torch\.backends\.cudnn\.enabled/False/g" ${PYTORCH}/torch/nn/functional.py
# for pytorch v0.4.1
sed -i "1254s/torch\.backends\.cudnn\.enabled/False/g" ${PYTORCH}/torch/nn/functional.py

# Note that instructions like # PYTORCH=/path/to/pytorch indicate that you should pick 
# a path where you'd like to have pytorch installed and then set an environment
# variable (PYTORCH in this case) accordingly.

• If you are using Anaconda, we suggest you create a new conda environment :conda env create -f multipose_environment.yaml. Maybe you should change the channels: and prefix: setting in multipose_environment.yaml to fit your own Anaconda environment.

  • source activate Multipose
  • pip install pycocotools

• You can also follow dependencies setting in multipose_environment.yaml to build your own Python environment.

  • Pytorch = 0.4.0, Python = 3.6
  • pycocotools=2.0.0, numpy=1.14.3, scikit-image=0.13.1, opencv=3.4.2
  • ......

• Build the NMS extension

  cd ./lib
  bash build.sh
  cd ..

Data preparation

You can skip this step if you just want to run inference on your own pictures using our baseline checkpoint

• For Training Keypoint Estimation Subnet, we followed ZheC/Realtime_Multi-Person_Pose_Estimation's first 4 Training Steps prepared our COCO2014 dataset (train2014, val2014 and mask2014).
• We also use COCO2017 dataset to train Person Detection Subnet.

Make them look like this:

${COCO_ROOT}
   --annotations
      --instances_train2017.json
      --instances_val2017.json
      --person_keypoints_train2017.json
      --person_keypoints_val2017.json
   --images
      --train2014
      --val2014
      --train2017
      --val2017
   --mask2014
   --COCO.json

Training

• Prepare
  • Change the hyper-parameter coco_root to your own COCO path.
  • You can change the parameter params.gpus to define which GPU device you want to use, such as params.gpus = [0,1,2,3].
  • The trained model will be saved in params.save_dir folder every epoch.
• Run:

python ./training/multipose_keypoint_train.py  # train keypoint subnet
python ./training/multipose_detection_train.py  # train detection subnet
python ./training/multipose_prn_train.py  # train PRN subnet

Validation

• Prepare checkpoint:

  • Download our baseline model (Google Drive, Tsinghua Cloud, backbone: resnet101) or use your own model.
  • Specify the checkpoints file path params.ckpt in file multipose_*_val.py.

• Run:

python ./evaluate/multipose_keypoint_val.py  # validate keypoint subnet on first 2644 of val2014 marked by 'isValidation = 1', as our minval dataset.
python ./evaluate/multipose_detection_val.py  # validate detection subnet on val2017
python ./evaluate/multipose_prn_val.py  # validate PRN subnet on val2017

To Do

• Keypoint Estimation Subnet for 17 human keypoints annotated in COCO dataset
• Keypoint Estimation Subnet with intermediate supervision
• Combine Keypoint Estimation Subnet with Person Detection Subnet(RetinaNet)
