I wrote the below code

    preprocessing_fn_map = {'cifarnet': cifarnet_preprocessing, 'inception': inception_preprocessing, 'inception_v1': inception_preprocessing, 'inception_v2': inception_preprocessing, 'inception_v3': inception_preprocessing, 'inception_v4': inception_preprocessing, 'inception_resnet_v2': inception_preprocessing, 'lenet': lenet_preprocessing, 'resnet_v1_50': vgg_preprocessing, 'resnet_v1_101': vgg_preprocessing, 'resnet_v1_152': vgg_preprocessing, 'resnet_v2_50': vgg_preprocessing, 'resnet_v2_101': vgg_preprocessing, 'resnet_v2_152': vgg_preprocessing, 'vgg': vgg_preprocessing, 'vgg_a': vgg_preprocessing, 'vgg_16': vgg_preprocessing, 'vgg_19': vgg_preprocessing}
    if (name not in preprocessing_fn_map):
        raise ValueError(('Preprocessing    name    [%s]    was    not    recognized' % name))
    def preprocessing_fn(image, output_height, output_width, **kwargs):
        return preprocessing_fn_map[name].preprocess_image(image, output_height, output_width, is_training=is_training, **kwargs)
    return preprocessing_fn

What's a good function header?
