Instructions

• Install Miniconda or Anaconda and then follow these steps:
  • create a conda environment using conda env create -f environment.yml
  • activate the environment using conda activate image-crop-analysis
• Put a dummy jpeg image at data/dummy.jpeg
• Put any additional images with *.jpeg extension in DATA_DIR, which is ./data
• If you just want to investigate how the model predicts the saliency map then you can use the notebook notebooks/Image Annotation Dash.ipynb
• To reproduce the analysis first prepare the data using notebooks/Data Preparation.ipynb and then run notebooks/Demographic Bias Analysis.ipynb
• To reproduce the plots first run notebooks/Demographic Bias Plots.ipynb
• If you want to explore how the library behind the dashboard works see notebooks/Image Crop Analysis.ipynb
• If you have the dataset prepared from the above steps then you can create the gender gaze dataset by running notebooks/Gender Gaze Analysis.ipynb

Docker Run

• Install docker
• Run the following commands in this root directory of this project:

docker build -t "image_crop" -f docker/Dockerfile .
docker run -p 9000:9000 -p 8900:8900 -it image_crop

• Open the jupyter lab URL shown in terminal.

Run on Google Colab

• Open a google colab notebook
• Run the following code in the cell where HOME_DIR variable is set:

try:
    import google.colab
    ! pip install pandas scikit-learn scikit-image statsmodels requests dash
    ! [[ -d image-crop-analysis ]] || git clone https://github.com/twitter-research/image-crop-analysis.git
    HOME_DIR = Path("./image_crop_analysis").expanduser()
    IN_COLAB = True
except:
    IN_COLAB = False

• Try the notebooks/Image Crop Analysis.ipynb notebook for example.
