OpenVINO demo error: xml file was not found

[Jian__Youling]

Hi there,

I am testing openVINO and NCS2 on win 10.
When I ran the demo sample I encountered this error:

I have checked the folder and there is indeed no such file.
Actually in the path "C:\Users\GenesysLogic SV team\Documents\Intel\OpenVINO", there only exists a folder named "inference_engine_samples_build".
Could someone help me with it? Thank you.

Hi Youling,

Did you try to run the demo once and it failed? If so, the directory was created and when the demo runs the second time it skips the model conversion as the directory already exists. Please try to delete the squeezenet1.1 directory and re-run the demo.

C:\Users\GenesysLogic SV team\Documents\Intel\OpenVINO\openvino_models\ir\FP16\public\squeezenet1.1

Regards,

Jesus

Hi Jesus,

I ran the demo command several times, not just only once.
And in the folder "C:\Users\GenesysLogic SV team\Documents\Intel\OpenVINO" there only exists a folder named "inference_engine_samples_build".
I don't see the folder "openvino_models" and the following folders/documents.
I think that's why it shows the error that couldn't find the "squeezenet1.1.xml" file.

This is because of the spaces in your build path. Check my comment here.

Hi Dutta Roy,

Thank you for the comment. It works.
But now I encountered new problems.
The error messages shows like below.

Can someone help with it?

Hi Youling,

I believe there is a compatibility issue with the networkx package. Could you try and install version 2.3 using the command "pip3 install networkx==2.3".

Try to run the demo again and let me know if it works.

Regards,

Jesus

Hi Jesus,

Yes it works. I have got the successful output.
Thank you very much for the support.
Also thanks to Dutta Roy again.

[Smith__Dale]

This works for me as well.

Why not add this to the OpenVino installation pages?

With this command it worked for me. However, when I ran again, the error came out again, so what I did was delete the file that indicated, in my case:
 

rm -rf /home/sergio/openvino_models/ir/FP16/public/

 I deleted all that folder and then I ran the script and now everything went ok.

I hope this information can help you.

If you don't  mind 'patching' your openvino install, you can fix the requirements files. This will find all of the requirements and insure that networkx is within the valid range.

sudo find /opt/intel/openvino/deployment_tools/model_optimizer/ -maxdepth 1 -name 'requirements*.txt' -exec sed 
-i 's/networkx>=1.11.*$/networkx>=1.11<2.4/' {} \

OpenVINO is installed "per version", so it's a good idea to run this against your "specific" branch, then future updates won't be affected -- unless they need to be. For my install, this looks like this:

sudo find /opt/intel/openvino_2019.1.144/deployment_tools/model_optimizer/ -maxdepth 1 -name 'requirements*.txt' -exec sed 
-i 's/networkx>=1.11.*$/networkx>=1.11<2.4/' {} \
