I am interested in knowing if anyone has setup OpenVino for Neural Compute Stick 2 ,either in windows 10 or Linux OS

[Luis_at_Intel · Accepted solution]

Hi @SDhim3​ ,

Thanks for reaching out. There are definitely many people that have setup the OpenVINO™ toolkit for the Intel® Neural Compute Stick 2 on both Windows* 10 and Ubuntu* 16.04. If you need help getting started I'd suggest to take a look at this guide https://software.intel.com/en-us/articles/get-started-with-neural-compute-stick, or if you are having issues with your setup please let us know so we can better assist you.

so post setting up openvino on windows & ubuntu

I picked action recognition example to run using NCS2:

While running the code on windows,getting below error:

 File "ie_api.pyx", line 85, in openvino.inference_engine.ie_api.IECore.load_network

 File "ie_api.pyx", line 92, in openvino.inference_engine.ie_api.IECore.load_network

RuntimeError: Can not init Myriad device: NC_ERROR

Not sure what is wrong,can anyone help?

Below is the Program Call with Parameters:

python action_recognition.py -m_en action-recognition-0001-encoder.xml   -m_de action-reocgnition-0001-decoder.xml  -i inputVideo.mp4 -d MYRIAD

looks like Device is not getting detected.

Hi @SDhim3​ ,

On the list of steps, have you configured Neural Compute Stick USB Driver for both environments? Also, have you tested that your installation is working properly? If not done so, I would suggest to follow Step 3 and Step 4 of the getting started guide for your device here https://software.intel.com/en-us/articles/get-started-with-neural-compute-stick.

Also, may I ask which version of the OpenVINO™  toolkit are you using? Please let me know, I will be waiting for your response.

Regards,

I am using w_openvino_toolkit_p_2019.2.242  on both Windows and Ubuntu(16.04 LTS)

Step 3 ran successfully

Connected NCS 2

Upon Executing Step4 on Ubuntu:

cd ~/intel/openvino/deployment_tools/demo

./demo_squeezenet_download_convert_run.sh -d MYRIAD

Following Error was generated:

Hi @SDhim3​,

Are you running Ubuntu on a Virtual Machine? If you are, there are additional steps that need to be completed. Please make sure your USB3.0 controller is enabled, you have installed the Extension Pack, and you have configured the USB filters for the NCS.

Regarding the Windows error, I am having trouble finding a solution since there isn't much information as to how to get there. Please share additional information that could help me reproduce the problem.

Regards,

@Luis_at_Intel​ 

[SDhim3]

Yes, on a Virtual Machine,I had done all the necessary steps for the USB to get recognized , It gets recognized, but upon running the program, name of device gets changed to Intel Corporation VSC Loopback Device[0100]

.

However it is running fine on Ubuntu now, I Added Both Devices in USB Filter:

• Movidius Ltd. Movidius MyriadX[0001]
• Intel Corporation VSC Loopback Device[0100]

For Windows,

I have installed CMAKE,PYTHON and Visual Studio 2019

I will share the full execution log ,which is getting printed in console, maybe that can help to understand ,and debug.

[Luis_at_Intel]

Hi @SDhim3​ ,

I am glad your Ubuntu VM is now working, some users are unaware of such filters and run into that issue every once in a while. I am glad this resolved your problem.

As far as your Windows 10 environment goes, is this running on a VM as well? I noticed you installed Visual Studio 2019, did you install it with MSBuild? Also don't forget to install the Model Optimizer dependencies as explained here. Another thing to keep in mind too is to make sure you initialize the Environment Variables using the bash script provided in the installation as shown here. Once your installation is complete, please also verify that is working using the demo scripts.

I hope this helps you. If you continue to run into issues with your Windows 10 environment, please share your environment details and as much information as possible so I can try to reproduce the problem and better assist.

Regards,

@Luis_at_Intel​

Error

[Luis_at_Intel]

Thanks for providing a detailed log. I just wanted to update you on what I have tried and the findings that I have so far:

• Taking a look at your logfile I can see that you are using Python 3.7.5
  • I attempted to use this version of Python*, I received a "unsupported version" message when setting up the environment variables (with the setupvars.bat script).
  • I would suggest removing this version and install Python 3.6.5 if possible.
• I am using Visual Studio 2019 Community with MSBuild installed
  • Checking the README file on the samples directory, I can see that for this particular Visual Studio version (2019) CMake version 3.14 is required.
    • This CMake version (3.14) doesn't match my installed version, I currently have CMake 3.15.2 installed.

My next step is to reinstall the required CMake version for the corresponding Visual Studio 2019 Community version, I would update you as soon as I find out more.

Regards,

@Luis_at_Intel​ 

[Luis_at_Intel]

I have an update, after following the steps listed below I can execute the demo script on Windows 10 just fine. I strongly believe the issue could be related to missing Visual Studio 2019 tools from the original install. Please take a look at your configuration and adjust the options accordingly, as mentioned in bullet #4 below (in BOLD). I am hoping this resolves the problem, please let me know your results from giving this a try.

• Download and install openvino for windows R2.0.1 2019
  • If you plan to use only NCS/NCS2 please check required components as mentioned here , otherwise stick to default selection of all components given by the installer
• Download and install cmake 3.14.6 (also tested 3.15.2 and it works)
  • Select "Add CMake to system path for the current user"
• Download and install python 3.6.5 (64-bit version)
  • Select "Add Python 3.6 to PATH"
    • Clarification: the previous error I mentioned was related to a 32-bit version of Python, not necessarily the 3.7 release
• Download and install Visual Studio 2019
  • Under Workloads select: 
    • Desktop development with C++
    • Universal Windows Platform development
  • Under Individual components select:
    • MSBUILD
  • If you missed selecting these options; re-run the Visual Studio 2019 installer and click Modify, then select options mentioned above. Otherwise you might see an error similar to this: 
    • Build tools for Visual Studio 2015 / 2017 / 2019 cannot be found. If you use Visual Studio 2017, please download and install build tools from https://www.visualstudio.com/downloads/#build-tools-for-visual-studio-2017 Error" when executing the verification scripts to verify installation.
• Set environment variables
  • open CMD window
  • execute "C:\Program Files (x86)\IntelSWTools\openvino\bin\setupvars.bat"
• Configure the Model Optimizer
  • Selected Option 1, configure the Model Optimizer for all supported frameworks at the same time:
    • cd C:\Program Files (x86)\IntelSWTools\openvino\deployment_tools\model_optimizer\install_prerequisites
    • install_prerequisites.bat
• Use Verification Scripts to Verify Your Installation
  • cd C:\Program Files (x86)\IntelSWTools\openvino\deployment_tools\demo\
  • demo_squeezenet_download_convert_run.bat -d MYRIAD
