    "# Neural style transfer on video\n",
    "Using modified code from `pytorch`'s neural style example, we show how to setup a pipeline for doing style transfer on video. The pipeline has following steps:\n",
    "1. Split a video into images\n",
    "2. Run neural style on each image using one of the provided models (from `pytorch` pretrained models for this example).\n",
    "3. Stitch the image back into a video.\n",
    "\n",
    "> **Tip**\n",
    "If your system requires low-latency processing (to process a single document or small set of documents quickly), use real-time scoring instead of batch prediction."
