Dependencies

Local machine:

• python==3.7.3
• torch==1.6.0
• requirements.txt
• GPU running option requires:
  • Installing CUDA 10.1 (Runtime + SDK) and configuring NVCC root directory into ENVIRONMENT PATH

Resources

Dataset	Dataset	Metadata (train, test)	Model (pytorch, onnx)
COFW	official	google / baidu	google / baidu
300W	official	google / baidu	google / baidu
WFLW	official	google / baidu	google / baidu

Preparation

• Step1: Install dependencies.
• Step2: Clone repo.
• Step3: Download dataset and metadata of each dataset to data/alignment/${dataset} folder.
• Step4: Set the target dataset through configuring the ${data_definition} variable in conf/alignment.py script.
• Step5: Run the scripts below.

Training in local machine

python main.py --mode=train --config_name=alignment --device_ids=0,1,2,3

Testing in local machine

python main.py --mode=test --config_name=alignment --pretrained_weight=${model_path} --device_ids=0

Evaluation in local machine

python evaluate.py --mode=nme --config_name=alignment --model_path=${model_path} --metadata_path==${metadata_path} --image_dir=${image_dir} --device_ids=0

Framework

The framework of ADNet.
