    "# How to fine-tune a T5 model with ONNX Runtime\n",
    "\n",
    "This notebook is largely inspired by the summarization [notebook of Transformers](https://github.com/huggingface/notebooks/blob/main/examples/summarization.ipynb) which takes PyTorch as backend for fine tuning.\n",
    "\n",
    "Here you will use the `ORTSeq2SeqTrainer` class in [Optimum](https://github.com/huggingface/optimum) library and take [ONNX Runtime](https://microsoft.github.io/onnxruntime/) as backend to accelerate the training. \n",
    "\n",
    "\n",
    "In this notebook, we will walk through the fine-tuning of [T5-small](https://huggingface.co/docs/transformers/model_doc/t5) model in the 🤗 Transformers for a summarization task. We will use the [XSum](https://arxiv.org/pdf/1808.08745.pdf) dataset (for extreme summarization) which contains BBC articles accompanied with single-sentence summaries, and the training as well as inference will be done by leveraging `ORTSeq2SeqTrainer` in Optimum! \n",
