Google Coral USB Edge TPU ML Accelerator coprocessor for Raspberry Pi and Other Embedded Single Board Computers

Product Information

In this tutorial, you will learn how to configure your Google Coral TPU USB Accelerator on Raspberry Pi and Ubuntu. You’ll then learn how to perform classification and object detection using Google Coral’s USB Accelerator.

I am extremely happy with this camera’s night vision performance. It truly does provide full color video under very low light conditions.

Here we are creating a Python virtual environment named coral using Python 3. Going forward, I recommend Python 3. The on-board Edge TPU coprocessor is capable of performing 4 trillion operations (tera-operations) per second (TOPS), using 0.5 watts for each TOPS (2 TOPS per watt). For example, it can execute state-of-the-art mobile vision models such as MobileNet v2 at almost 400 FPS, in a power-efficient manner. See below section for performance benchmarks. The Google Coral USB Accelerator is an excellent piece of hardware that allows edge devices like the Raspberry Pi or other microcomputers to exploit the power of artificial intelligence applications. In addition, it has excellent documentation containing everything from the installation and demo applications to building your own model and a detailed Python API documentation.

An individual Edge TPU is capable of performing 4 trillion operations (tera-operations) per second (TOPS), using 0.5 watts for each TOPS (2 TOPS per watt). How that translates to performance for your application depends on a variety of factors. Every neural network model has different demands, and if you're using the USB Accelerator device, total performance also varies based on the host CPU, USB speed, and other system resources. PyCoral is built on top of Tensorflow Lite and allows you to run Tensorflow Lite models on the Edge TPU without writing lots of boilerplate. The 3 elements with the highest “classification score” (above a threshold value) are determined in the process.• Subsequently, each detected object is marked on the image. Today we’ll be focusing on the Coral USB Accelerator as it’s easier to get started with (and it fits nicely with our theme of Raspberry Pi-related posts the past few weeks).

Key benefits of the Coral USB Accelerator

This is only recommended if you really need the maximum power, as the USB Accelerator's metal can become very hot to the touch when you're running in max mode. QNAP reserves the right to replace partial parts or accessories if the original is no longer available from its manufacturer/supplier. Any replacement would be fully tested and verified to meet strict compatibility and stability guidelines and will deliver identical performance to the original.

The reason is that the object_detection.py script is not filtering on a minimum probability. You could easily modify the script to ignore detections with < 50% probability (we’ll work on custom object detection with the Google coral next month).

The NCS2 can work with Ubuntu, CentOS, Windows 10, and other operating systems. It can support TensorFlow, Caffe, ApacheMXNet, Open Neural Network Exchange, PyTorch, and PaddlePadle via an Open Neural Network Exchange conversion.operating frequency. Otherwise, you can install the maximum frequency runtime as follows: sudo apt-get install libedgetpu1-max you can instead flash your SD card with the AIY Maker Kit system image, which includes everything you need to use
