Here are instructions on how to run Google's coral ([https://coral.withgoogle.com/tutorials/accelerator/]) 

== Install ==

 wget http://storage.googleapis.com/cloud-iot-edge-pretrained-models/edgetpu_api.tar.gz  # 6 seconds
 tar xzf edgetpu_api.tar.gz
 cd python-tflite-source
Edit last line of install.sh to use python3
 bash ./install.sh         # 22 seconds, 33s on Surface

=== Installing on Bone ===
This install.sh file checks for Raspberry Pi, but not the Bone.  There's a simple edit that can add the bone.

First run
 bone$ '''cat /proc/device-tree/model'''
 TI AM335x BeagleBone Black
Remember the string that is returned.  Now edit install.sh.  You'll several lines that look almost like:
   elif [[ "$board_version" == "TI AM335x BeagleBone Black"* ]]; then
    platform="raspberry_pi_3b+"
    echo -e "${GREEN}Recognized as Raspberry Pi 3 B+!${DEFAULT}"

Copy one set of three lines and edit to use the string returned by the '''cat''' command.

Save the file and run
 bash install.sh
 reboot

Mine to some 9 and a half minutes on BeagleBone Black and 7.5 minutes on an x15.  The reboot seems necessary to get the right USB name to show up.

== Set up hardware ==
Plug in.  If you are running a virtual machine, have it capture
 Global Unichip Corp.
A then it disappears and the following appears
 Google Inc.

On my Surface I had to 
* quit VirtualBox
* On your host machine, download the '''VirtualBox Extension Pack''' from: https://www.virtualbox.org/wiki/Downloads. 
* on your host, login as Administrator
* run VirtualBox, but don't start a machine
* go to Extensions and click the '''+''' button and add the extension pack you just downloaded
* go to the USB settings and select the USB3.0 xHCI button
* logoff as Administrator
* run VirtualBox and start your machine
* repeat the plugging in steps above

=== Test ===
 # From the python-tflite-source directory
 cd edgetpu/

 python3 demo/classify_image.py \
 --model test_data/mobilenet_v2_1.0_224_inat_bird_quant_edgetpu.tflite \
 --label test_data/inat_bird_labels.txt \
 --image test_data/parrot.jpg

The following took 6 seconds on my x86 Ubuntu virtual machine, 5 on a native Ubuntu install and 12 seconds on the BeagleBone Black and 9 seconds on an x15.
