Complete the below
def get_depth_fn(depth_multiplier, min_depth):

    ''''Builds a callable to compute depth (output channels) of conv filters.
    Args:
    depth_multiplier: a multiplier for the nominal depth.
    min_depth: a lower bound on the depth of filters.
    Returns:
    A callable that takes in a nominal depth and returns the depth to use.'
