In this directory, you will find two Jupyter notebooks. The first is an end-to-end deep learning training tutorial which borrows the open source code from the TensorFlow image classification tutorial, demonstrating how to train the model and then convert to OpenVINO Intermediate Representation (OpenVINO IR). It leverages the tf_flowers dataset which includes about 3,700 photos of flowers.
The second notebook demonstrates how to quantize the OpenVINO IR model that was created in the first notebook. Post-training quantization speeds up inference on the trained model. The quantization is performed with the Post-training Quantization with NNCF from OpenVINO Toolkit. A custom dataloader and a metric will be defined, and accuracy and performance will be computed for the original OpenVINO IR model and the quantized model on CPU and iGPU (if available).
301-tensorflow-training-openvino.ipynb- Demonstrates how to train, convert, and deploy an image classification model with TensorFlow and OpenVINO.
301-tensorflow-training-openvino-nncf.ipynb- Demonstrates how to quantize the OpenVINO IR model that was created by the previous notebook.
