Fail to run train.lua

[shuait]

This is maybe a trivial question but I'm completely new to torch, I tried to search on Google but no luck. I'm working with a Ubuntu 14.04 machine, cuda 7.0 and cudnn R4 version. I prepared all training files and when running train.lua it gives me this error:

@haibin894609937 I still has no clue what caused the problem, tried to reinstall torch and that failed too.

I run it on centos7 cuda8.0

You guys are working on VQA dataset, right? If yes, I guess the problem is on your vqa_data_prepro.json and vqa_data_prepro.h5. You can try to use other dataset the author provided, cocoqa. If you replace the above two files by cocoqa_data_prepro.json and cocoqa_data_prepro.h5, all the code should run well. When I replace those two files, everything works well. So, you also can try this, then you will know the problem is the generation of prepro files.
