unavailable function in demo!from config import cfg, get_affine_transform , etc

[rangerToby]

i try to run the demo code，but i find some unavailable function in demo code:
import _init_paths
import models
from config import cfg
from config import update_config
from core.function import get_final_preds
from utils.transforms import get_affine_transform

pose_model = eval('models.'+cfg.MODEL.NAME+'.get_pose_net')(
    cfg, is_train=False
)

is there somebody who run the demo code successfully?

-_-，there is a hidden step in dome's readme：
copy demo/inferrence.py into tools/ ，and run the command from [pose_root]
