It seems some files are missing in your data folder. Do you have the generated question and answer vocab files (data/questions_vocab.t7 and data/answers_vocab.t7)? If not, you can either download them from links given in the readme, or if you want to generate your own vocab files, make sure you've downloaded the VQA dataset.
yes, I have have the generated question and answer vocab files (data/questions_vocab.t7 and data/answers_vocab.t7). can u give a demo

You've to extract all the zipped JSON files into the data folder as well. For example, MultipleChoice_mscoco_train2014_questions.json.
@anthonyyuan were you able to get this to work?
