About the pretrained model

[pantingchn]

Hi, I just wonder where can i get the pretrained models, whose paths in the json files are like:
"pretrained_backbone": "/data4/livesegmentation/thuync/PyTorch-pretrained/resnet18.pth"
or
"pretrained_backbone": "/root/pretrain/resnet18.pth"
or
"/workspace/pretrain/resnet18.pth"?
