OpenVINO Ubuntu Xenial, Virtualbox and Vagrant Install, Intel NCS2 (Neural Compute Stick 2)

#OpenVINO Ubuntu Xenial, Virtualbox and Vagrant Install, Intel NCS2 (Neural Compute Stick 2)

Prerequsites

Download Latest VirtualBox from [https://www.virtualbox.org/wiki/Downloads] https://www.virtualbox.org/wiki/Downloads

Make sure to download extension pack

Oracle VM VirtualBox Extension Pack

Download and Install Vagrant from

[https://www.vagrantup.com/downloads.html] https://www.vagrantup.com/downloads.html

First step is to setup VM.

vagrant up

Vagrant is configured to apply all usb filters required to access Neural Compute Stick 1 and 2 inside Virtualbox Ubuntu Xenial VM

This will create VM on your host machine with name "OpenVinoVM"

This will also automatically download OpenVINO to /home/vagrant/openvino

Setup

Install OpenVINO Dependencies

cd /home/vagrant/openvino/l_openvino_toolkit_p_2019.1.094/ && sudo ./install_openvino_dependencies.sh

Install OpenVINO

cd /home/vagrant/openvino/l_openvino_toolkit_p_2019.1.094/ && sudo ./install.sh

This will have multiple manual steps like accepting license and selecting kind of installation

Default installation path the download configured in Vagrantfile /opt/intel/openvino_2019.1.094

Setup Vars

source /opt/intel/openvino_2019.1.094/bin/setupvars.sh

echo "source /opt/intel/openvino_2019.1.094/bin/setupvars.sh" >> /home/vagrant/.bashrc

Install UDEV Rules

THese are required for USB to be activated and used

sh /opt/intel/openvino_2019.1.094/install_dependencies/install_NCS_udev_rules.sh

Update UDEV Rules are below

sudo vi /etc/udev/rules.d/97-myriad-usbboot.rules

I modified MODE to 666 from 660. OpenVINO has 660 as default.

SUBSYSTEM=="usb", ATTRS{idProduct}=="2150", ATTRS{idVendor}=="03e7", GROUP="users", MODE="0666", ENV{ID_MM_DEVICE_IGNORE}="1" SUBSYSTEM=="usb", ATTRS{idProduct}=="2485", ATTRS{idVendor}=="03e7", GROUP="users", MODE="0666", ENV{ID_MM_DEVICE_IGNORE}="1" SUBSYSTEM=="usb", ATTRS{idProduct}=="f63b", ATTRS{idVendor}=="03e7", GROUP="users", MODE="0666", ENV{ID_MM_DEVICE_IGNORE}="1"

Reload UDEV

sudo udevadm control --reload-rules && sudo udevadm trigger && sudo ldconfig

Configure Model Optimizer

cd /opt/intel/openvino_2019.1.094/deployment_tools/model_optimizer/install_prerequisites && sudo ./install_prerequisites.sh

If you dont want to run optimizer for all different kind of model you can choose specific optimizer

Example: sudo ./install_prerequisites_caffe.sh ( For Caffe Model) Example: sudo ./install_prerequisites_tf.sh ( For Tensorflow Model)

Verify if USB is attached

Type lsusb

You should see some USB device with vendor id like

Bus 002 Device 002: ID 03e7:2485

Finally Test

cd /opt/intel/openvino_2019.1.094/deployment_tools/demo && ./demo_squeezenet_download_convert_run.sh

This should print something like this

Downloading Public Model and Running Test

cd /opt/intel/openvino_2019.1.094/deployment_tools/tools/model_downloader/

List public models that are known to work with OpenVINO

python3 downloader.py --print_all

Download a specific model, say GoogLeNet V2

Make sure vagrant has access to folder

sudo chmod -R 777 /opt/intel/openvino_2019.1.094/deployment_tools/tools/model_downloader/

python3 downloader.py --name googlenet-v2

Convert Pretained Model to IR ( Intermediate Represenation. This can run on multiple hardware)

cd /opt/intel/openvino_2019.1.094/deployment_tools/tools/model_downloader/classification/googlenet/v2/caffe

Use model optimizer to convert googlenet.caffemodel to IR

/opt/intel/openvino_2019.1.094/deployment_tools/model_optimizer/mo.py --data_type FP16 --input_model googlenet-v2.caffemodel --input_proto googlenet-v2.prototxt

Deploy the converted IR model onto Intel NCS 2 using the toolkit's IE API

cd /opt/intel/openvino_2019.1.094/deployment_tools/inference_engine/samples/python_samples

Download a test image from the internet

sudo wget -N https://upload.wikimedia.org/wikipedia/commons/b/b6/Felis_catus-cat_on_snow.jpg

Run an inference on this image using a built-in sample code

python3 classification_sample/classification_sample.py -m /opt/intel/openvino_2019.1.094/deployment_tools/tools/model_downloader/classification/googlenet/v2/caffe/./googlenet-v2.xml -i Felis_catus-cat_on_snow.jpg -d MYRIAD

This should give results like

Image Felis_catus-cat_on_snow.jpg
