"Failed to link vertex and fragment shaders" while using Posenet on ios (Mobile Safari 18.1.1)

[Pensarfeo]

Hi, I saw from my analytics this following error in production.

"Failed to link vertex and fragment shaders" while initializing posenet.

This is my initialization.

    const initTensor = zeros([256, 256, 3])
    await this.poseDetector.estimatePoses(initTensor)

It has only happened twice in the last couple of years but I would like to know what to do and how to try recovering the system.

I am quite sure the error happened on ios Mobile Safari 18.1.1.

these are the tfjs versions I use

@tensorflow-models/pose-detection": "^2.1.3 @tensorflow/tfjs-backend-webgl": "^4.21.0 @tensorflow/tfjs-backend-webgpu": "^4.21.0 @tensorflow/tfjs-converter": "^4.21.0 @tensorflow/tfjs-core": "^4.21.0

Any advice would be welcomed!

Hi @Pensarfeo ,

I wasn't able to replicate the issue on my end, but based on my understading, it seems that the problem is related to your device running GPU out of memory. I believe images with a resolution of 256x256 should work fine with the poseDetector models, but larger images may cause memory issues.

I came across this discussion that might be helpful: Thread.

Thank You!!

Hi @shmishra99, thanks for giving it a try :) I also never saw this issue, it seems rare, i have seen it only a few times on thousands of devices that used my app. My questions is more about how to handle the failure rather than how to fix it.

Shall I just try to run the model again? Shall I force reload the page? Is there a way to check how much memory is available?
