INFO net.py: 89: old_res5_2_branch2c_bn_b not found

I have installed CBNet follow the Detectron repo install tutorial.
However,when I run the infer_simple.py.I got the error.
INFO net.py: 89: old_res5_2_branch2c_bn_b not found
The command I use:

python tools/infer_simple.py \   
 --cfg configs/cascade_rcnn_baselines/e2e_mask_cascade_rcnn_X-152-32x8d-FPN-        IN5k_1.44x.yaml
 --output-dir /tmp/detectron-visualizations \     
--image-ext jpg     \
--wts https://dl.fbaipublicfiles.com/detectron/ImageNetPretrained/25093814/X-152-32x8d-IN5k.pkl       
demo

What should I do to fix it?
