[Dimitry_N_Intel]

Hi ,

1. I downloaded and install OpenVino toolkit  2019 R1.

2. I am trying to create a standalone simple sample to test our network, as in hello_classiification  

4. I copy all needed dll into my run directory.

5.I have following exception at line InferencePlugin plugin(PluginDispatcher().getSuitablePlugin(TargetDevice::eCPU));

Dear Dmitry:

Please read my response to the following post:

https://software.intel.com/en-us/forums/computer-vision/topic/806679

However, you will want to use 2019:

https://github.com/opencv/dldt/blob/2019/inference-engine/README.md

For building a standalone OpenVino applications, the method suggested in the above forum answer is the best approach. 

Hope it helps,

Thanks,

Shubha

Dear Shubha,

I don't understand what official installation toolkit good for if I cannot use it?

Thanks

Dear Dimitry N. ,

Of course you can use the non-open source OpenVino. But if you want to write your own custom app from scratch with DLLs located in non-standard directories -- you should use the github open source version. If you download the official OpenVino (non-open source release) you should not move DLLs around or you will suffer exceptions as you are seeing. dldt open source is meant for custom development.

The below forum post (with my answers) may help you:

If you want to continue using the non-open source version please study the setupvars.bat under bin. Make changes accordingly.

Thanks,

Shubha

Dear Dmitry, 

Also check out my answer to this forum post. I think it will help you. Please keep in mind that I'm advising this customer to also use the dldt github version:

https://software.intel.com/en-us/forums/computer-vision/topic/806679

The basic idea is this. It's more straightforward to build a standalone application with dlls located on a Timbuktu fileserver - if you use the dldt github approach. Not to say that it's not possible using the non-open-source - of course it is. It's just more straightforward (and less error-prone) using the dldt github. 

Thanks,

Shubha
