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

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

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_linu...

 

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.

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.
