Cannot infer on Movidius (NCS2) using OpenVINO Workbench through Docker: Drivers setup failed?

[Benguigui__Michael]

Hi all, 

I am trying to run some inferences using the OpenVINO Workbench Docker image  https://hub.docker.com/r/openvino/workbench . Everything works well using my CPU as targeted device (Configuration -> Select Environment). But I get the following error when I select my Intel Movidius Myriad X VPU (a Neural Compute Stick  2): 

"Cannot infer this model on Intel(R) Movidius(TM) Neural Compute Stick 2 (NCS 2). Possible causes: Drivers setup failed. Update the drivers or run inference on a CPU." (cf attached screenshot).

I did not change the start_workbench.sh script. Here are my execution params:

./start_workbench.sh -IMAGE_NAME openvino/workbench -TAG latest -ENABLE_MYRIAD -DETACHED -ASSETS_DIR /hdd-raid0/openvino_workbench

However, I can play with the NCS2 using the classification or cross check commands provided by https://hub.docker.com/r/openvino/ubuntu18_dev.

Any idea ?
Thxxxx!

All I can say is this is a very old product question. You can't infer anything. Because a wild guess you are using the device's graphics. In fact it's supposed to be empty. Good luck777

Greetings,

You need to install the NCS2 driver correctly before doing any inferencing or etc with it.

Both MYRIAD(NCS2) and hddl is supported as in here: https://docs.openvinotoolkit.org/latest/workbench_docs_Workbench_DG_Install_Workbench.html

Make sure to select according to your OS and follow the additonal steps required to activete the NCS2 usage: https://docs.openvinotoolkit.org/latest/openvino_docs_IE_DG_supported_plugins_MYRIAD.html

Sincerely,

Could you please tell me where is mentioned that NCS2 drivers are required, when following the Docker based installation ?

This is how you can use a Docker* Image for Intel® Vision Accelerator Design with Intel® Movidius™ VPUs: https://docs.openvinotoolkit.org/latest/openvino_docs_install_guides_installing_openvino_docker_linux.html

Kindly navigate to the specific topic. You will find that there are a few additional steps to be done before NCS2 can be used with Docker.

and see Configuration guide for HDDL device or Configuration Guide for Intel® Vision Accelerator Design with Intel® Movidius™ VPUs as mentioned in the above link.

Sincerely,

I finally followed the non docker based installation procedure

https://docs.openvinotoolkit.org/latest/workbench_docs_Workbench_DG_Install_from_Package.html

(including)-> "Install OpenVINO™ Package"

(including)->   https://docs.openvinotoolkit.org/latest/openvino_docs_install_guides_installing_openvino_linux.html 

(including)->"Steps for Intel® Neural Compute Stick 2"

At the end, it is asked to start the workbench container (even if you followed the non docker based installation).. and inferences on the Myriad work.

Thx a lot for your quick replies... I think Intel must reorganize this documentation.

Okay first of all thanks. I just reminded myself about this topic.

And this topic reminded me.

I just wanted to let you know of the basics of the Edge computing first. Just in case it is effecting your progress.

In order to complete any assigments that you planned to program.

You will first need the 

Intel® Neural Compute Stick 2

I will include just the several closed and open data sheets that I was strangely fond to. They all cover different roles for demostrating this unit.

This is the Data Sheet PDF

https://www.intel.com/content/dam/support/us/en/documents/boardsandkits/neural-compute-sticks/NCS2_Datasheet-English.pdf 

The current ark solution, sometimes they include purchase options;

when I say current; I mean it or(they) can change;

https://ark.intel.com/content/www/us/en/ark/products/140109/intel-neural-compute-stick-2.html 

This page covers the getting started with the unit;

https://software.intel.com/content/www/us/en/develop/articles/get-started-with-neural-compute-stick.html 

And last in the list is the AI program data sheet; it's all online.

https://software.intel.com/content/www/us/en/develop/articles/using-and-understanding-the-intel-movidius-neural-compute-sdk.html 

To be honest the most important part I wanted to mention is I don't view my clipart photos when logged in. I appologize if there are any formating issues or page loading problems with the site.

Thanks, again.

The issue is noted.

Thanks for your feedback.

If you don't have any further inquiries, shall I close this thread?

Sincerely,

Iffa

[Benguigui__Michael]

Yes! Thx a lot.

Greetings,

Intel will no longer monitor this thread since this issue has been resolved. If you need any additional information from Intel, please submit a new question

Thanks.
