./Images

For real, create a directory with name mscoco inside this directory. For each of train, val and test, create directories with names train2014, val2014 and test2015 respectively inside mscoco directory, download respective images from MS COCO website and place them in respective folders.
For abstract, create a directory with name abstract_v002 inside this directory. For each of train, val and test, create directories with names train2015, val2015 and test2015 respectively inside abstract_v002 directory, download respective images from VQA download page and place them in respective folders.

./PythonHelperTools

./PythonEvaluationTools

./Results

OpenEnded_mscoco_train2014_fake_results.json (an example of a fake results file for v1.0 to run the demo)
Visit [VQA evaluation page] (http://visualqa.org/evaluation) for more details.

./QuestionTypes

This directory contains the following lists of question types for both real and abstract questions (question types are unchanged from v1.0 to v2.0). In a list, if there are question types of length n+k and length n with the same first n words, then the question type of length n does not include questions that belong to the question type of length n+k.
