Temporary solution: this guide

Also, the help for running the various scripts is incomplete (in some cases incorrect). For instance, main page says "own_image.py" can be run via

python extract_features.py --caffe /path/to/caffe

But it also requires path to VGG model and prototxt.

Thanks for reporting this. @arushk1 can you have a look at this?

The VGG prototxt file is already included in the scripts folder, and according to the instructions, I have asked users to download the caffemodel file and place it in the scripts folder. In any case, I added an update for setting a custom path to the VGG caffemodel file here : ttps://github.com/arushk1/visual-qa/, and submitted a PR. @dhruvbatra @avisingh599

I am not able to see the PR.
