 4. Next, you can use the `build_default` python script to get the default neural network models, compile them with

     [Vela](https://review.mlplatform.org/plugins/gitiles/ml/ethos-u/ethos-u-vela) is an open-source python tool converting
     TensorFlow Lite for Microcontrollers neural network model into an optimized model that can run on an embedded system
     containing an Ethos-U55 NPU. It is worth noting that in order to take full advantage of the capabilities of the NPU, the

 This will fetch all the models into `resources_downloaded` directory. It will
 also optimize the models using the Vela compiler for default 128 MAC configuration
 of Arm® Ethos™-U55 NPU.
