Failed to train the model by following the instructions given with the command "th train.lua"

[sami5596]

I'm trying to train the model by following the already given instructions and using the dataset as mentioned in the instructions i.e. coco 2014 dataset. But whenever I try to run command "th train.lua" I get the following error:

shoaib@shoaib-HP-ENVY-Notebook:~/deepmask$ th train.lua

我用TORCH_LUA_VERSION=LUA52 ./install.sh 安装torch7解决的
