Distortions in using IPEX with triplane NeRF on TripoSR

[SAint7579]

Describe the bug

Issue:

I am trying to run TripoSR (original repository: https://github.com/VAST-AI-Research/TripoSR) on an Intel Developer Cloud instance. I made the necessary changes to the main repo to use IPEX and optimize the model for float32. The model is running successfully. However, when I check the results, the output file is distorted significantly. I optimized and ran this for CPU as well, and the results there look fine. You can see the outputs in the following image:

The glb on the left is from the CPU and on the right is from an Intel GPU, performed on the same image.

Reproducing the error:

• You can checkout the following repository and move to the ipex branch:

git clone https://github.com/Dimensify/TripoSR/
cd TripoSR
git checkout ipex
pip install -r requirements.txt

• To run the code, use the command python run.py examples/chair.png --output-dir output/ --model-save-format glb --render

• You can check the render in output/0/render.mp4

[Vasud-ha]

@SAint7579 Thanks for reporting it, we will investigate and get back to you.

[rskasturi]

Hey @Vasud-ha, the distortions seems to be observed with latest IPEX version(v2.1.20+xpu) as well.

[Vasud-ha]

Hi @rskasturi, thanks for sharing the updates, we can reproduce the issue on our end and are currently in the process of debugging it.

[Vasud-ha]

The first output difference on CPU and GPU is occurring at this layer of the model.

image_tokenizer.model.embeddings.dropout

[Vasud-ha]

Hi @SAint7579 could you please try with the latest ipex 2.1.30+xpu, results seem good with the latest version on GPU Max 1100.

[SAint7579]

@Vasud-ha, yes, it works on our IDC machine with IPEX 2.1.30. Thanks a lot for the help!

Close per above comments from @SAint7579 , thanks.
