machine learning - when I use facebook tools:deekmask, some errors came out and I can't find that's why -


i installed proper packages, such as: torch, cocoapi, cudnn, cunn etc. , deployed deepmask correspondingly.

but, when training model, typing: th train.lua, errors follows:

pls me, much!

i figure out myself!

the $deepmask dir need high authority access before, chmod 777 -r $deepmask, problem solved.
