Res2Net for Pose Estimation using Simple Baselines as the baseline
Res2Net for Pose Estimation
Update
- [2020.3.13] Res2Net_v1b based Pose Estimation results are released now.
Introduction
This repo uses Simple Baselines as the baseline method for Pose Estimation.
Res2Net is a powerful backbone architecture that can be easily implemented into state-of-the-art models by replacing the bottleneck with Res2Net module. More detail can be found on "Res2Net: A New Multi-scale Backbone Architecture"

Note:
- Flip test is used.
- Person detector: prdbox refers to the Person detector that has person AP of 56.4 on COCO val2017 dataset; GTbox refers to the GT of person detection.
Quick start
Installation
-
Install pytorch >= v1.0.0
-
Clone this repo, and we'll call the directory that you cloned as ${POSE_ROOT}.
-
Install dependencies:
pip install -r requirements.txt
-
Make libs:
cd ${POSE_ROOT}/lib make
-
Install COCOAPI:
# COCOAPI=/path/to/clone/cocoapi git clone https://github.com/cocodataset/cocoapi.git $COCOAPI cd $COCOAPI/PythonAPI # Install into global site-packages make install # Alternatively, if you do not have permissions or prefer # not to install the COCO API into global site-packages python3 setup.py install --user
Note that instructions like # COCOAPI=/path/to/install/cocoapi indicate that you should pick a path where you'd like to have the software cloned and then set an environment variable (COCOAPI in this case) accordingly.
-
Init output(training model output directory) and log(tensorboard log directory) directory:
mkdir output mkdir log
Your directory tree should look like this:
${POSE_ROOT} ├── data ├── experiments ├── lib ├── log ├── models ├── output ├── tools ├── README.md └── requirements.txt
-
Download pretrained models of Res2Net following the instruction from Res2Net backbone pretrained models. Please change the path to pretrained models (PRETRAINED: ) in config files:

Data preparation
For MPII data, please download from MPII Human Pose Dataset. The original annotation files are in matlab format. We have converted them into json format, you also need to download them from OneDrive or GoogleDrive. Extract them under {POSE_ROOT}/data, and make them look like this:
${POSE_ROOT}
|-- data
`-- |-- mpii
`-- |-- annot
| |-- gt_valid.mat
| |-- test.json
| |-- train.json
| |-- trainval.json
| `-- valid.json
`-- images
|-- 000001163.jpg
|-- 000003072.jpg
For COCO data, please download from COCO download, 2017 Train/Val is needed for COCO keypoints training and validation. We also provide person detection result of COCO val2017 and test-dev2017 to reproduce our multi-person pose estimation results. Please download from OneDrive or GoogleDrive. Download and extract them under {POSE_ROOT}/data, and make them look like this:
${POSE_ROOT}
