About training in step 2 anhd step 3

[huytuong010101]

I see the config in step 2 is:
...
BACKBONE_RESUME_ROOT = './backbone_resume.pth'
HEAD_RESUME_ROOT = './head_resume.pth'
TRAIN_FILES = './dataset/face_train_ms1mv2.txt'
BACKBONE_LR = 0.05
PRETRAINED_BACKBONE = ''
PRETRAINED_QUALITY = ''
...
So where can i get the backbone_resume.pth and head_resume.pth
And where can i get pretrained_backbone_resume.pth and pretrained_qulity_resume.pth in step 3?
...
BACKBONE_RESUME_ROOT = ''
HEAD_RESUME_ROOT = ''
TRAIN_FILES = './dataset/face_train_ms1mv2.txt'
BACKBONE_LR = 0.05
PRETRAINED_BACKBONE = ''
PRETRAINED_QUALITY = ''
PRETRAINED_BACKBONE = 'pretrained_backbone_resume.pth'
PRETRAINED_QUALITY = 'pretrained_qulity_resume.pth'
...
