Containerize the app

Build a container with Python App

Build container with base image with :

  • OpenVINO
  • Python 3.7
  • Ubuntu 18.04 (16.04 should work but have not tested yet)

Example :

./build-app-container.sh openvino-container:ubuntu18.04_openvino2020.2.120_cp3.7 myregistry

Run the container

You need to run the container with several flags for GPU and Myriad Access

  • GPU Access
    --device /dev/dri
  • VPU (Myriad) Access --device-cgroup-rule='c 189:* rmw' -v /dev/bus/usb:/dev/bus/usb

Example :

docker run -it --device-cgroup-rule='c 189:* rmw' -v /dev/bus/usb:/dev/bus/usb --device /dev/dri -v ${HOME}/data:/home/openvino/data -p 8080:8080 daisukeiot/openvino-container:ubuntu18.04_openvino2020.2.120_cp3.7_app

For UP2 (ATOM) :

docker run -it --device-cgroup-rule='c 189:* rmw' -v /dev/bus/usb:/dev/bus/usb --device /dev/dri -v ${HOME}/data:/home/openvino/data -p 8080:8080 daisukeiot/openvino-container:ubuntu18.04_openvino2020.2.120_r1.15_cp3.7_app

Custom Tensorflow Build

ATOM Processors (e.g. UP2) do not support AVX, therefore, Tensorflow must be re-compiled without AVX support.

Make sure to use Tensorflow without AVX support, otherwise, Model Conversion and Inference won't work.
