# Hello Reshape SSD Python Sample

This sample demonstrates how to do synchronous inference of object detection models using [Shape Inference feature](https://docs.openvino.ai/2026/openvino-workflow/running-inference/model-input-output/changing-input-shape.html).

Models with only 1 input and output are supported.
