Then please follow directions on installing GroundingDINO: https://github.com/IDEA-Research/GroundingDINO

You also need to make sure you have downloaded the GroundingDINO weights and put them in the weights directory. You can do this by running

bash scripts/download_grounding_dino_weights.sh

Then you can download and extract all the model generated images by running

bash scripts/download_images.sh

To run skill based evaluation, please run

bash scripts/evaluate_skill_based.sh

Note: In the paper, we use the first 1000 IDs located in the data/skill_based/random_ids_{skill}.json file, where skill is any of object, count, spatial, etc.

• This is already implemented in the code

To run open ended evaluation, please run

bash scripts/evaluate_open_ended.sh

Then run the following to get the scores

python src/utils/score_open_ended.py

When running a script, pass the --visualization_savepath argument to choose where to save the explainations. The visual explainations (bounding boxes) will be saved in the ../images/ directory and then a JSON file will also be saved in the root path that includes the text explainations along with a path to the coorsponding images if it is available.

We've released a fine-tuned (on ChatGPT outputs) LLama2 7B model. If you do not want to use ChatGPT then you can use this model instead. Please refer to this code file.
