Hi! I've encountered some issues while developing mobile detection app.
On my device Xiaomi Redmi Note 4 in logs appear two errors:

  • On NN interference start there are
    `-------- GLSL link error: Warning: barrier used in non-uniform control flowWarning: barrier used in non-uniform control flow

But these 3 errors didn't occur on another tested device that is Huawei Mate 10.

Another have place if I try run WebCamTexture together with Barracuda Worker on my Xiaomi :
`

`
I have no idea if these errors have something in common so I post them as one issue.

They didn't occur also on my laptop while testing.
I use YOLOv2 Tiny network, downloaded already in onnx format.

Some of these errors might appear on mobile devices, as some of compute kernels are too complex for simpler mobile GPUs, but in many cases Barracuda should fallback to some less complicated implementation.
Does Barracuda produce outputs you would expect or do exceptions break execution completely?

My phone supports OpenGLES 3.2, so if
the error appear depends on something more than ES version?

Exception allocation 0x0xc0000001 already registered causes app kill so there aren't any output.

At the moment we dropped GLES support on Android and focusing on Vulkan instead. Please let us know if Vulkan doesn't work for you.

I have updated project to barracuda 0.7.0 and sadly the error still occur. I have tested lately and I noticed that first frame pass without problem but on second appears crash with the same error.
As I run inference only once on start the allocation error also appears but doesn't cause crash.
I have uploaded the project so you can check this by yourself. https://github.com/wojciechp6/YOLO-UnityBarracuda
