Train with the `resume` option fails

Hi, I'm sorry for creating several issues, but i think different problems should be on different issues. Now I'm trying to run train script with --resume option, but it does not work.

I did this command: python3 train_coco_pose_estimation.py --gpu 0 --out result/20171213/ --resume result/20171206/model_iter_560000 (result/20171206/model_iter_560000 is my model file created by training procedure)

and I get this error

ono@xxxx:~/Chainer_Realtime_Multi-Person_Pose_Estimation⟫ python3 train_coco_pose_estimation.py --gpu 0 --out result/20171213/ --resume result/20171206/model_iter_560000

I'm still debuggin by myself, but if you have any idea about this, I would like to know it. Thank you!
