    # OPTIONAL DEPENDENCIES
    # Here you can add any dependencies your package may have. You can use
    # conda for packages available through conda, or pip for any other
    # packages. You should leave the `numpy=$NUMPY_VERSION` in the `conda`
    # install since this ensures Numpy does not get automatically upgraded.
