Hello blechatellier,

 

Thank you for contact Intel technical support, we can see that you can not run a demo on a MacOS, could you please answer some questions we have for you:

 

Which version of MacOS are you using? 

Are you running inference on a physical machine or are you using a virtual machine?

Did you install the libusb library to perform inference on Intel(R) Neural Compute Stick 2? If you did not install, please install it by running brew install libusb as mentioned here.

 

If you have more questions, please feel free to ask us, and we will help you further. 

Thank you.

Hello blechatellier, 

Thank you for your response. In order to continue helping you with your issue, we want to know some additional information: 

How are you connecting the NCS2 device, 2.0, 3.0 or USB hub, (is it powered)? 

Could you please run the command: system_profiler SPUSBDataType  on your terminal to check if it is detecting your device? 

 

Thank you.

Thank you for the information,

 

As another step, can you try to run the demo using a different USB port please? At this moment we are trying to test the demo in our lab, and we will contact you back soon with more information.

 

Thank you.

I've also tested on Ubuntu 18.04 (not in a VM or Docker) and I get the same error on the squeeznet sample. Some time I see the follow extra error:

 

E: [ncAPI] [925785] [classification_] ncDeviceOpen: 859 Device doesn't appear after boot

Thank you for the issue update,  

  

We are currently working on installing Mojave 10.14.4, to run the squeezenet demo from our end to help you with a solution. While we are working on this, could you please let us know the models of the Macs where you tried to test it before?  

  

Thank you.

Thank you for the response,

 

We were able to run the demo successfully in three different systems running MacOS

10.14. Could you please provide the software versions of Python, Cmake, and

xcode you are using please. I was having issues running the demo with Python

version 3.7.4 but upgrading to version 3.7.5 helped.

 

Best regards,

Mauricio R.

Python 3.7.4

Cmake 3.15.3

 

Xcode is not installed (just the required packages). Isn't the squeeznet demo using c++ and not python?

I've tried with Python 3.7.5, same error.

 

Running into new errors with the model optimizer,

 

[ ERROR ] -------------------------------------------------

[ ERROR ] ----------------- INTERNAL ERROR ----------------

[ ERROR ] Unexpected exception happened.

[ ERROR ] Please contact Model Optimizer developers and forward the following information:

Thank you for your response.

 

When you are installing OpenVINO, Apple Xcode* Command Line Tools is one of the software requirements. Could you please install Apple Xcode* Command Line Tools, and then try to run the demo again?

 

You can see the official instructions here.

 

On the other hand, I see that your new error is with the model optimizer, could you please start a new discussion to keep this discussion specific to the demo issue? Please include additional information about the new issue. What command are you using? What framework and topology is your model based on?

 

Thank you.

Apple Xcode* Command Line Tools was already installed but I tried the latest and still running in the same issue.

The first time I run "system_profiler SPUSBDataType", the device shows up. After the running the demo I get:

 

E: [ncAPI] [  629734] [] ncDeviceOpen:859 Device doesn't appear after boot

[ ERROR ] Can not init Myriad device: NC_ERROR

 

If I run "system_profiler SPUSBDataType" again, the device is not showing, I have to unplug and re-plug.

Hello blechatellier,

 

As these steps did not work, I recommend you to uninstall OpenVINO and re-install it as root. Another recommendation from us is to update macOS to 10.14.6 version, and try to run the demo again with these new features, please.

 

Thank you.

Ok, will try, what do you make of my latest comment about the device disappearing when running the demo?

Upgraded MacOS to 10.14.6, installed openvino as root and still running in the same issue. Can you comment on why the device disappears after it tries to boot?
