Error during IMX500 conversion

[JochenSchmitz]

Hello,
when exporting a YOLOv8 model to IMX500 format, I get the following error messages:
The export still works, but I'm not sure if the quantized model is really good.
Best regards,
Jochen

👋 Hello @JochenSchmitz, thank you for sharing your question and for your interest in Ultralytics 🚀! We recommend taking a look at the Ultralytics Docs for detailed guidance and examples on export-related workflows, including IMX500 export processes.

To assist further, if this is a 🐛 Bug Report, please provide us with a minimum reproducible example that demonstrates the issue. This will help us effectively debug and identify the underlying cause. For example, include your environment details, the exact ultralytics version used, and the specific export command you are running.

Upgrade

Please ensure that you are using the latest version of Ultralytics and related dependencies. You can upgrade with the following command:

pip install -U ultralytics

Recommended Environments

We also suggest testing in one of the following verified environments to rule out potential issues related to dependencies:

• Notebooks with free GPUs:
  
  
  
• Other environments such as Google Cloud, AWS, or Docker .

@JochenSchmitz hi Jochen, the warnings and errors appear to be related to the Model Compression Toolkit (MCT) during the quantization process. While the export may succeed, these issues could affect the quantized model’s quality. Please ensure you're using compatible versions of PyTorch and MCT and that your model complies with IMX500 requirements. If issues persist, consider referring to the detailed MCT quantization support in the documentation here or consult the toolkit's official resources.

@glenn-jocher Hi. I am sure i follow this guideline. I can not do any more than

yolo export format=imx model=best.pt data=data.yaml imgsz=640

Maybe someone found the same issue and a solution

Regards

Jochen
