Preparation

Please download the corresponding benchmarks in 'data' directory. Then prepare the environment as in requirement.txt. We have uploaded several trained models on online (Baidunetdisk(link：https://pan.baidu.com/s/1qcGmdmZlmAgqsAzw_i5BhA code：mapz) or Drive (https://drive.google.com/drive/folders/1ketomxctszHo7jpGQS3RxbZGq7e_M3e4?usp=sharing)).
