  • Hi @bigfoottt

    The Neural Compute SDK only supports the original Intel Movidius Neural Compute Stick. You will need to download and install the OpenVINO toolkit for the Intel Neural Compute Stick 2.

    Take a look at the getting started guide for the NCS 2:

  • I faced same Error with Windows 10 OS.
    I tried running my Myriad X (named UP AI CORE X) with the tutorial below.
    https://software.intel.com/en-us/articles/get-started-with-neural-compute-stick

    but, at "Step 4. Test the installation", an error occured.
    * the device could be seen as Movidius Myriad X on device manager.
    * after the error occurd, the device can not be seen.

    Best Regards.

    I show a part of the Error

  • Hi @yamaken

    Which version of the OpenVINO toolkit are you using? Which version of Visual Studio do you have installed? I don't have an AI Core X available to test right now, I will try to get a hold of one.

    Try to install the latest OpenVINO toolkit version R1.1, it was just released a couple of days ago.
