[Bug] MYRIAD unable to run

[Averen19]

Hello, I'm trying to run a yolov5 model with openvino and NCS2. My assumption with installing openvino is that it comes preinstalled with NCS2 dependencies, but when I'm trying to run with NCS2 I get the following issue:

Hi, have you tried to run setupvars.bat script before running the inference?

[Averen19]

@mateusztabaka yes I have. I am able to run with my cpu but not with MYRIAD. It seems that the openvino 2022 does not have the inference engine folder which was found in the 2021 version, so I do not know where to install the myriad driver neccessary.

@Averen19, Do you use PyPI version? MYRIAD plugin has been removed from PyPI wheel because of license incompatibility. Please try a distribution: https://registrationcenter-download.intel.com/akdlm/irc_nas/18618/w_openvino_toolkit_p_2022.1.0.643_offline.exe

Hi, whats the difference between your link and the one available from intel directly [https://www.intel.com/content/www/us/en/developer/tools/openvino-toolkit/download.html] I tried to download your version but it says I already have the files.

Oh, that's the same but just a direct link. I just checked my Windows install and can find myriad plugin:

cache.json                       openvino_intel_gpu_plugin.dll*
gna.dll*                         openvino_intel_hddl_plugin.dll*
openvino.dll*                    openvino_intel_myriad_plugin.dll*
openvino_auto_batch_plugin.dll*  openvino_ir_frontend.dll*
openvino_auto_plugin.dll*        openvino_onnx_frontend.dll*
openvino_c.dll*                  openvino_paddle_frontend.dll*
openvino_gapi_preproc.dll*       openvino_tensorflow_fe.dll*
openvino_hetero_plugin.dll*      pcie-ma2x8x.elf
openvino_intel_cpu_plugin.dll*   plugins.xml
openvino_intel_gna_plugin.dll*   usb-ma2x8x.mvcmd

Can you please share exact commands which are used? Try on a new prompt:

call "C:\Program Files (x86)\Intel\openvino_2022\setupvars.bat"

then verify that OpenVINO Python is from C:\Program Files (x86)\Intel\openvino_2022:

import openvino
print(openvino.__file__)

should be:

C:\Program Files (x86)\intel\openvino_2022\python\python3.8\openvino\__init__.py

(3.8 or other Python version)

I cant seem to find the setupvars.bat found in previous versions of Openvino, and in the 2022 version it doesnt have folders for inference engine or model optimizer either.

Seems like it's not properly installed - try double-click on w_openvino_toolkit_p_2022.1.0.643_offline.exe and follow install GUI or by the following command:

start /WAIT w_openvino_toolkit_p_2022.1.0.643_offline.exe -s -a --silent --eula accept

I have tried reinstalling again, and to ensure that I did install with Movidius, the following image can be referrenced.

I tried your example and got the following:

Sorry - I forgot a dot symbol

print(openvino.__file__)

[Averen19]

Ah thank you very much, I finally got it to work. But my end goal is to run this on raspberry pi with ncs2. I tried finding openvino 2022 for raspbian but was unable to find it and the latest version was only until 2021.2 https://download.01.org/opencv/ . What do you recommend the steps I should take to be able to run inferrencing on RPI?

[brmarkus]

There were several questions asked about RPI and MyriadX/NCS2.
MyriadX is used successfully on RPI(4).
You can find several (solved) issues under "https://github.com/openvinotoolkit/openvino/issues?q=is%3Aissue+RPI".

@Averen19 I will work with you on your original issue here: #11458 for the raspberry pi package. Closing this issue as your MYRIAD issue has been resolved for Windows.
