    "# Quantization of Image Classification Models\n",
    "\n",
    "This tutorial demonstrates how to apply `INT8` quantization to Image Classification model using [NNCF](https://github.com/openvinotoolkit/nncf). It uses the MobileNet V2 model, trained on Cifar10 dataset. The code is designed to be extendable to custom models and datasets. The tutorial uses OpenVINO backend for performing model quantization in NNCF, if you interested how to apply quantization on PyTorch model, please check this [tutorial](../pytorch-post-training-quantization-nncf/pytorch-post-training-quantization-nncf.ipynb).\n",
    "\n",
    "This tutorial consists of the following steps:\n",
    "\n",
    "- Prepare the model for quantization.\n",
    "- Define a data loading functionality.\n",
    "- Perform quantization.\n",
    "- Compare accuracy of the original and quantized models.\n",
    "- Compare performance of the original and quantized models.\n",
