NAPARI is a recent software which has been promoted for the bioimage analysis community by the Chan Zuckerberg Initiative. It enables fast prototype interface for python script. As a consequence NAPARI constitutes a good tool for deep learning developers eager to easily allow their non coding collaborators to press button ergonomic user interfaces. In this workshop you will learn your first step in NAPARI starting from its installation up to the development of your own first basic NAPARI plugin. We will teach you how to make this plugin accessible on the NAPARI platform. Finally we will empower you with deep learning NAPARI plugin adapted to segmentation, classification or object detection. A demo of human in the loop approach of AI will be demonstrated with this plugin.
