Solved: Perfectly set up OpenVino multiple times, encountering same NCS2 error on multiple installations

Matthew_Beck · ‎01-18-2024

Hello,

I successfully downloaded OpenVino 2022.3.1 for Raspberry Pi 64bit OS with compatible Python 3.9.18, and have gotten setupvars.sh to successfully initialize OpenVino every time terminal starts up by adding this line to my ~/.bashrc file with the 2022.3.1 guide here: https://docs.openvino.ai/2022.3/openvino_docs_install_guides_installing_openvino_raspbian.html and this was my output:

~/.bashrc line:

# initialize OpenVino Python 3.9.18 environment
source /opt/intel/openvino_2022.3.1/setupvars.sh

terminal output:

[setupvars.sh] OpenVINO environment initialized
matthewthomasbeck@raspberrypi:~ $

I have also successfully downloaded OpenVino 2022.2.0.7713 for Raspberry Pi 32bit OS with compatible Python 3.7.17, and have gotten setupvars.sh to successfully initialize OpenVino every time terminal starts up by adding this line to my ~/.bashrc file per the tutorial here: https://community.intel.com/t5/Intel-Distribution-of-OpenVINO/Followed-Arm7-single-board-tutorial-for-NCS2-keep-encountering/m-p/1562572/emcs_t/S2h8ZW1haWx8dG9waWNfc3Vic2NyaXB0aW9ufExSQ1pXOUY3WFRINlJUfDE1NjI1NzJ8U1VCU0NSSVBUSU9OU3xoSw#M30515

and did the 2022.2.0.7713 setup here: https://docs.openvino.ai/archive/2022.2/openvino_docs_install_guides_installing_openvino_raspbian.html#development-and-target-systems and got an output that looked like this:

~/.bashrc line:

# initialize OpenVino Python 3.7.17 environment
source /opt/intel/openvino_2022.2.0.7713/setupvars.sh

terminal output:

[setupvars.sh] OpenVINO environment initialized
matthewthomasbeck@raspberrypi:~ $

So as you can see, OpenVino was installed perfectly per the instructions given.

BUT as soon as I try and continue to the section where I configure my NCS2 and go here: https://docs.openvino.ai/archive/2022.2/openvino_docs_install_guides_configurations_for_ncs2.html#ncs-guide-raspbianos when I enter this line into terminal for both versions:

terminal input for OpenVino 2022.3.1

$ sh /opt/intel/openvino_2022.3.1/install_dependencies/install_NCS_udev_rules.sh

terminal input for OpenVino 2022.2.0.3317

$ sh /opt/intel/openvino_2022.2.0.3317/install_dependencies/install_NCS_udev_rules.sh

I get this error statement for both versions:

terminal output for both versions:

File '97-myriad-usbboot.rules' is missing. Please make sure you installed 'Inference Engine Runtime for Intel Movidius VPU'.

How can I proceed? I am terrified that whatever I do, I'll break my installation, I've already tried 8 times to get this to work and am starting to run out of hope for this thing.

Hi Matthew_Beck,

Thank you for reaching out to us.

The error is because OpenVINO™ was not able to locate the "97-myriad-usbboot.rules" file. For your information, you need to be in the "install_dependencies" directory first before running "install_NCS_udev_rules.sh" file:

cd /opt/intel/openvino_2022.3.1/install_dependencies
sh install_NCS_udev_rules.sh

Hope this helps!

Regards,

Megat

So I continued forward with your command on both installations, but now I am getting errors on both installations when I continue with the NCS2 setup I mentioned:

This solution worked, thanks!

I followed your instructions, but encountered errors when doing subsequent commands found here: https://docs.openvino.ai/archive/2022.2/openvino_docs_install_guides_configurations_for_ncs2.html#ncs-guide-raspbianos I run into more errors as soon as I enter this line:
