Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

onnx 1.2 models (Custom Vision) on HoloLens

I'm using the Unity Project from this blogpost: https://mtaulty.com/2018/03/29/third-experiment-with-image-classification-on-windows-ml-from-uwp-on-hololens-in-unity/

I had issues that my own exported models don't work with the the code after some point. Now it is possible to export onnx models of version 1.2, but the the old code seems to not be compatible with the new version.

in the line var evalOutput = await this.learningModel.EvaluateAsync(this.inputData); in the MainScript it throws The binding is incomplete or does not match the input/output description. (Exception from HRESULT: 0x88900002)

Does someone know what I need to change so it works with the new version on HoloLens? Thanks in advance!

    I'm not sure whether this is the answer for you or not but I notice that when I try and export an ONNX V1.2 model out of the custom vision service then the website does flag to me;

    "ONNX1.2 only works for Windows 10 Build 17738 or higher"

    Is your Windows 10 here at version 17738 or beyond?

  • Hi Mike!

    I always thought it's about the SDK and I'm using the SDK 17763 to build the App in Unity. ( https://imgur.com/w2kXfLU )

    But I just checked this PC and the HoloLens and of course the Build number is lower.

    So I guess I have to update them somehow.
