The paper is in draft review. I hope the article will be hired.

I don't know if there are any risks in open source code before employment, but I have promised to update the new results so the new result is released.

I hope this work can help you and if you have any question or are interested in this direction you can join in the QQ group 767732179.

I hope to learn and progress with you.

The newst result has reach none accuracy drop with 58.2% Params pruned.

Some feature work is underwork. I will update and maintain in time, and welcome you to provide your own scheme for communication.

Fig1. the architecture of the proposed HRNet

Fig2. the pruning area of the proposed HRNet

• Flip test is used.
• Person detector has person AP of 56.4 on COCO val2017 dataset.
• GFLOPs is for convolution and linear layers only.
• _best is best purning rate of HRnet and _extreme is higher purning rate.
• APRP is the selection mothed using to generate APR.

The code is developed using python 3.6 on Centos7. NVIDIA GPUs are needed. The code is developed and tested using 2 NVIDIA 2080Ti GPU cards.

1. Install pytorch >= v1.0.0 following official instruction.

2. Clone this repo, and we'll call the directory that you cloned as ${POSE_ROOT}.

3. Install dependencies:

   pip install -r requirements.txt
   

   or

   pip3 install -r requirements.txt
   

4. Make libs:

   cd ${POSE_ROOT}/lib
   make
   

5. 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.

6. Init log(tensorboard log directory) directory:

   mkdir log
   

   Your directory tree should look like this:

   ${POSE_ROOT}
   ├── experiments
   ├── lib
   ├── models
   ├── output
   ├── tools 
   ├── README.md
   └── requirements.txt
   

7. Download pretrained models of original HRNet from (GoogleDrive or OneDrive)

For APRCP HRNet you can get our prtrain model in : https://drive.google.com/file/d/1-EXl9dSatzmUSGpWGuBFlcPPM9T8Gcfr/view?usp=drivesdk And new result using v1 and v2 is here: https://drive.google.com/file/d/16qW7gPrtjaQzyiuE9xEkkqBxaDYSvOoa/view?usp=sharing

For a purned model, there are two main file:

pruneXXX.txt // to build model
XXXXXXXX.pth // weight of model

We first use pruneXXX.txt to get model structure,then copy weight form XXXXXXXX.pth

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_data}, and make them look like this:

2. channel puring rate select

python3 tools/normal_regular_select \
    --cfg experiments/coco/hrnet/w48_384x288_adam_lr1e-3.yaml --save output\
or use:
python3 tools/golden_cut_select.py \
    --cfg experiments/coco/hrnet/w48_384x288_adam_lr1e-3.yaml --save output\

Note in line 138 : max_perf,max_acc = getpruneffects(0,"original")

getpruneffects should be replaced by getpruneffects_v2 or getpruneffects_v3 if you want to use v2 or v3 pruning mothed.

python3 tools/retrain.py \
    --cfg experiments/coco/hrnet/w48_384x288_adam_lr1e-3.yaml --save output --percent [you get in purning select or another float in range(0,1)] \
