Failed to create plugin MKLDNNPlugin.dll

Hi, I've just installed version 2020 of OpenVINO Toolkit according to the installation guide at here, all of the steps goes well until running the two verification script. I got an error that said something like

Failed to create plugin MKLDNNPlugin.dll for device CPU 
Please check your environment 
cannot load library <path to openvino mkldnn>\mkldnnplugin.dll

on the last part of "demo_squeezenet_download_convert_run.bat", I've also tried to run "demo_security_barrier_camera.bat" and got the same error. Can anyone help me? Thanks!

OS: Windows 10 64-bit

Processor: Intel Atom x5-z8350

Hi Adrian.

Have you followed "Set the Environment Variables" step? https://docs.openvinotoolkit.org/latest/_docs_install_guides_installing_openvino_windows.html#set-the-environment-variables

OpenVINO toolkit environment variables are removed when you close the Command Prompt window. As an option, you can permanently set the environment variables manually.

Hello, zhang, duoduo

Can I please take a look at program's full command line output (demo security barrier camera or squeezenet download convert run)?
And please also specify what CPU do you use in your system?

Yes, I have followed the set environment from bin/setupvars.bat, and I still have the same error

Hi Adrian.

This error might be related to the fact that Atom x5-z8350 processor does not support AVX instructions that required for Model Optimizer usage. And as I see, demo_squeezenet_download_convert_run.sh uses Model Optimizer for model conversion.
This is a known limitation described here https://docs.openvinotoolkit.org/latest/_docs_MO_DG_Known_Issues_Limitations.html

However, demo security barrier camera script should not have any references to Model Optimizer, since it downloads the model already converted to IR format.
So please double confirm if you see the same error message using demo security barrier camera. And if so, please provide us with a full command's output.

Thanks.
Best regards, Max.

This isn't just MO. Inference Engine fails on CPUs without AVX2 as well - https://github.com/opencv/dldt/issues/387

So, it seems like this isn't fixed in 2020.2 (based on the reports here - https://github.com/opencv/dldt/issues/387#issuecomment-613432147 )... any idea when we may expect the fix?
