Can't parse message of type "caffe.NetParameter"

[nvnnghia]

I run the demo and get this error. Please help.

Command line is:
./tools/test_net.py --gpu 0 --def models/pascal_voc/ResNet-50/rfcn_end2end/test_agnostic.prototxt --net resnet50_rfcn_final.caffemodel --imdb coco_2014_test --cfg experiments/cfgs/rfcn_end2end_ohem_pascal_voc.yml --set TEST.SOFT_NMS 1

error:
