Model Creation C++ Sample

This sample demonstrates how to execute an synchronous inference using model built on the fly which uses weights from LeNet classification model, which is known to work well on digit classification tasks.

You do not need an XML file to create a model. The API of ov::Model allows creating a model on the fly from the source code.

For more detailed information on how this sample works, check the dedicated article
