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

Product Information

The moment I saw the Framework laptop and the expansion card system I knew I have to make something. My benchmark is frame rate using MobileNetSSD_V2 trained on the coco data set with USB3 TPU or NCS2 coprocessors. And a French manufacturer checks the integrity of food containers as they speed down the production line. This is essential to build AI inferencing solutions in the field, with many distributed devices in a challenging setting (temporary power and network constraints).

However, most edge AI devices are able to provide offline capabilities (built-in storage, robust auto-rebooting capabilities). A Python virtual environment is an isolated development/testing/production environment on your system — it is fully sequestered from other environments.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). Inside the box is a USB stick and a short USB-C to USB-A cable intended to connect to to your computer. You’ll then learn how to perform classification and object detection using Google Coral’s USB Accelerator. PyCoral is a Python library built on top of the TensorFlow Lite library to speed up your development and provide extra functionality for the Edge TPU. For compatibility with the Edge TPU, you must use either quantization-aware training (recommended) or full integer post-training quantization.

I have HP Folio 9480m) A friend of mine saw me having a bad time and gave me a Google Coral USB Accelerator which sped up the training process substantially. I thought it was super easy to configure and install, and while not all the demos ran out of the box, with some basic knowledge of file paths, I was able to get them running in a few minutes. Download the bird classifier model, labels file, and a bird photo: bash examples/install_requirements.I would be interested to see what kind of creative projects people would come up with, as a laptop isn’t your typical machine learning platform.

Its a dynamic product range adapting to many legacy systems and products as well as being prepared to design into the future.We also learned how to install the edgetpu library into a Python virtual environment (that way we can keep our packages/projects nice and tidy). It brings a rich set of features including video recording, re-streaming, and motion detection, and supports multiprocessing. The Coral USB Accelerator comes in at 65x30x8mm, making it slightly smaller than its competitor, the Intel Movidius Neural Compute Stick. I’ve used/tried them all, but have settled on pip, virtualenv, and virtualenvwrapper as the preferred tools that I install on all of my systems. If I can solve the thermal issues, I'm getting great results with MobilenetSSD_v2 for person detection on a Nano using an A+E Key TPU module (~15 fps round robbin with five 4K cameras, limitation is rtsp stream decoding, not TPU inference rate) and TensorRT based yolov4 as a verification step on detections to further push the false positive rate towards zero.
