How to Use

• Clone the project
• Create environment via conda
  • For Mac

    conda env create -f env_mac.yaml

  • For Linux (CPU only)

    conda env create -f env_linux_cpu.yaml

  • For Linux (CUDA 10.2)

    conda env create -f env_linux_cuda102.yaml

  • For Linux (CUDA 11.3)

    conda env create -f env_linux_cuda113.yaml

• Download the train and test set I created at here, or download the full dataset if you want to process the data from scratch.
