Features' file loading in the code

[ifmaq1]

Hi,
I am confused regarding how you tackled the "bbox" information in the code. I can see loading the image features x from ".npz" file only.

Also, it is mentioned that we can work with grid features as well. Grid features' file with ".pth" extension only contains features/weights with tensor size [1, 2048, 19, 29](a sample feature file) and not any bounding box information, object detection etc. Then how can we cater those features without any such information.

The bbox information is an optional feature in this repo, our models do not use this by default.
