How to run the code in cpu mode properly?

[ghost]

First of all, thanks for your great work! Now I am trying to run the code and I change the value of gpu in main_cls.lua and main_cls_int.lua to zero already. But when I run train_coco.sh, I still got such an error: Users/yobichi/torch/install/bin/luajit: main_cls.lua:56: attempt to call field 'setDevice' (a nil value). The full message is as below:

Could you tell me what's wrong with it and how can I fix it? Thanks in advance!
