+# Post-Training Quantization of Resnet18 PyTorch Model exported to torch.fx.GraphModule
+
+This example demonstrates how to use Post-Training Quantization API from Neural Network Compression Framework (NNCF) to quantize PyTorch models exported to torch.fx.GraphModule on the example of Resnet18 post-training quantization, pretrained on Tiny ImageNet-200 dataset.
+
+The example includes the following steps:
+
+- Loading the Tiny ImageNet-200 dataset (~237 Mb) and the Resnet18 PyTorch model pretrained on this dataset.
+- Exporting model to torch.fx.GraphModule by torch.export.export function.
+- Quantizing the model using NNCF Post-Training Quantization algorithm.
+- Output of the following characteristics of the quantized model:
+  - Accuracy drop of the quantized model (INT8) over the pre-trained model (FP32)
+  - Performance speed up of the quantized model (INT8)
+
+## Install requirements
+
+At this point it is assumed that you have already installed NNCF. You can find information on installation NNCF [here](https://github.com/openvinotoolkit/nncf#user-content-installation).
+
+To work with the example you should install the corresponding Python package dependencies:
+
+```bash
+pip install -r requirements.txt
+```
+
+## Run Example
+
+It's pretty simple. The example does not require additional preparation. It will do the preparation itself, such as loading the dataset and model, etc.
+
+```bash
+python main.py
+```
