Install Packages

• (Recommended) Create Conda environment with Python 3.9
• Install PyTorch with the correct CUDA version
• Install dependencies for SPICE metric

  cd caption_evaluation_tools/coco_caption
  bash get_stanford_models.sh
  cd ../../
  

• Install other dependencies

  pip install -r requirements.txt
  

Download Dataset & Pretrained Model

• Install p7zip (required for unpacking dataset)

  # if using conda
  conda install bioconda::p7zip
  # if installing to system
  # sudo apt-get install p7zip-full
  

• Download Clotho dataset

  bash download_clotho.sh
  

• Install Git-LFS

  # if using conda
  conda install conda-forge::git-lfs
  git-lfs install
  
  # if installing to system
  # curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh | sudo bash
  # sudo apt-get install git-lfs
  # git-lfs install
  

• Get pretrained model (stored on HuggingFace)

  bash download_model.sh
  

Reproduce Best Model Results

• Run inference & evaluation code

  bash run_sampling_reranking.sh
  

  • metrics can then be found at ./exp/inference_evaluation_nucleus_t0.5_p95/inference_metrics.json

(Bonus) Augmented Dataset

Our 50K mix-up caption augmentations generated by ChatGPT (see paper Section 2.3 for details) can be found at:
