Error occurred when compile model for MYRIAD (NCS2)

Hi, I am trying to run my model on NCS2(Myriad X).

on my windows11 computer, It just works fine with ncs2.

 

But when I'm trying to run on my ubuntu machine, its generate unexpected NC_ERROR. Also, it works fine when I set device to "CPU".

 

My ubuntu host (A) is 20.04, and run the openvino ubuntu docker image (B) on it.

 

I think I'm totally set my environment in machine (A). 

 

Env

host : ubuntu 20.04

docker: openvino/ubuntu18_dev:latest

running command:

docker run --rm --privileged -v /dev:/dev --net=host ...

 

lsusb | grep 2485

Bus 001 Device 010: ID 03e7:2485 Intel Movidius MyriadX

 

groups

junpyo sudo users docker enerzai

 

 

ls /etc/udev/rules.d

70-snap.snapd.rules 70-snap.snap-store.rules 97-myriad-usbboot.rules

Hi JunpyoSeo,


Thanks for reaching out to us.


Please try run inference inside the Docker image with the following command:

docker run -it --device-cgroup-rule='c 189:* rmw' -v /dev/bus/usb:/dev/bus/usb --rm openvino/ubuntu18_dev:latest


Next, run the hello_query.py sample to detect whether Myriad (NCS2) is available or not.



Regards,

Peh
