[UltralyticsAssistant]

👋 Hello, thank you for your interest in Ultralytics and exploring integrations with the Sony IMX500! 🚀

For those looking to dive deeper into this topic, the Ultralytics Docs are a great starting point. They contain sections dedicated to various integrations, including Sony IMX500, with detailed instructions on how to export your YOLO models efficiently.

If you're here to report a 🐛 bug, please provide a minimum reproducible example. This will help us better understand and assist with the issue you're facing.

For general usage, upgrading to the latest version of Ultralytics might resolve some issues you encounter. Make sure your environment is updated with the latest package:

pip install -U ultralytics

For interactive discussions, consider joining the Ultralytics community on Discord 🎧, our Discourse forum, or participate in threads on our Subreddit.

Our team will assist you soon, but for now, these resources should help you get started! 😊

Environments

Feel free to run YOLO in any of these verified environments with preinstalled dependencies:

• Notebooks with free GPU:
• Google Cloud and Amazon environments as per GCP Quickstart Guide and AWS Quickstart Guide
• Docker Image: with guidance in our Docker Quickstart Guide

Status

Our continuous integration (CI) ensures all models and integrations, including Sony IMX500, are tested across platforms. Check our CI status here for the latest updates:

I ran into some python dependency issues when trying to run the 1st example. i started with python 3.12. ultralytics asks for tensorflow 2.12 which seems to clash with the requirements of the converter tools. Downgrading python to 3.11 is not enough. Tensorflow version must be higher than 2.12.

❯ uv add "model-compression-toolkit==2.1.1" "sony-custom-layers==0.2.0" "tensorflow==2.12.0" "imx500-converter[pt]==3.14.3"
  × No solution found when resolving dependencies for split (python_full_version >= '3.12' and platform_system == 'Darwin' and sys_platform == 'darwin'):
  ╰─▶ Because tensorflow==2.12.0 has no wheels with a matching Python version tag and your project depends on tensorflow==2.12.0, we can conclude that your project's
      requirements are unsatisfiable.

# downgraded python to 3.11

  × No solution found when resolving dependencies for split (python_full_version == '3.11.*' and platform_system == 'Darwin' and sys_platform == 'darwin'):
  ╰─▶ Because onnxruntime>=1.17.0,<=1.17.3 depends on numpy>=1.24.2 and only the following versions of onnxruntime are available:

          onnxruntime==1.17.1
          onnxruntime==1.17.3
          onnxruntime>1.18.dev0
      we can conclude that onnxruntime>=1.17.0,<1.18.dev0 depends on numpy>=1.24.2.
      And because uni-pytorch==1.10.0 depends on onnxruntime>=1.17.0,<1.18.dev0, we can conclude that uni-pytorch==1.10.0 depends on numpy>=1.24.2.
      And because imx500-converter[pt]==3.14.3 depends on uni-pytorch==1.10.0 and tensorflow==2.12.0 depends on numpy>=1.22,<1.24, we can conclude that tensorflow==2.12.0
      and imx500-converter[pt]==3.14.3 are incompatible.
      And because your project depends on imx500-converter[pt]==3.14.3 and tensorflow==2.12.0, we can conclude that your project's requirements are unsatisfiable.

I tested on ubuntu 22 machine. Found solution after some testing. Here is the project file.

[project]
name = "ultralytics-imx500"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"
requires-python = "~=3.11.0"
dependencies = [
    "imx500-converter[pt]==3.14.3",
    "model-compression-toolkit==2.1.1",
    "sony-custom-layers==0.2.0",
    "tensorflow~=2.14.0",
    "ultralytics>=8.3.31",
]

It could also be good to mention that converter installation at some point might ask for sudo pwd since it requires java.

[glenn-jocher]

@alexander-sony thank you for sharing your solution and insights on resolving the dependency issues. It's great to see the community collaborating to overcome challenges. If you have further questions or need additional assistance, feel free to ask here.

[JochenSchmitz]

Hello Alexander-Sony,
I have the problem with the sudo password. Unfortunately, I don't know where to enter it. I'm not asked either. I'm using the current Ultralytics Docker container on Ubuntu 22. But installing with pip also gives the same error. Here is the complete output. Can you please give me a tip.
Thank you
Jochen

Hello, I found it myself. Installing openjdk-17-jdk before starting the export prevents the problem.
Best regards
Jochen

[glenn-jocher]

Thank you for sharing your solution, Jochen! Pre-installing openjdk-17-jdk is an excellent approach to prevent the issue. If you have further questions or run into additional challenges, feel free to ask here.

[ARCHANGELOVE]

Hi there it doesnt support for yolov8n-obb model because it shows me
TypeError: decode_bboxes() got an unexpected keyword argument 'xywh'

[glenn-jocher]

@ARCHANGELOVE it seems you're encountering an issue with the decode_bboxes() function in the YOLOv8n-obb model. This error might be due to an unsupported or incorrect argument being passed. Please ensure that you're using the latest version of the Ultralytics package and verify the function's parameters in the documentation. If the problem persists, consider opening an issue with detailed information on your setup and code snippet for further assistance.

[ARCHANGELOVE]

Yep noted but as i know the box decoding for OBB is differ from AABB because the model convertion using yolov8n.pt works fine and the conversion was successful

yolo export model=yolov8n-obb.pt format=imx

i face the error when i convert the obb model

my ultralytics vertion is in latest aswell

[glenn-jocher]

It seems like the decode_bboxes() function currently doesn't support the OBB model conversion for the yolov8n-obb.pt to IMX500 format. This might be due to differences in bounding box representation between OBB and AABB models. Please ensure you're using the latest version of the Ultralytics package and consider checking the latest documentation or opening an issue on GitHub for further assistance.

[marcivanmanalac]

Hello there,

Are there any tips on IMX exporting for later YOLO models such as V11?

[glenn-jocher]

@marcivanmanalac to export later YOLO models like YOLOv11 to IMX format, you can follow a similar process as mentioned for YOLOv8, using the model.export(format="imx") function with INT8 quantization. Ensure your model is well-prepared by training effectively and refer to the Sony IMX500 Export Guide for detailed instructions and deployment steps. Let us know if you need further assistance!

[marcivanmanalac]

Hi Glenn,

Yes, that was what I had attempted in the following format success = model.export(mode=model, format="imx", int8=True)

but I get a �[34m�[1mIMX:�[0m export failure ❌ 0.0s: IMX export is only supported for YOLOv8 detection models error from line 1111 on from export_imx( ).

[glenn-jocher]

@marcivanmanalac the error occurs because IMX export currently supports only YOLOv8 detection models and is not implemented for YOLOv11. Please refer to the Sony IMX500 Export guide for supported workflows. YOLOv11-specific export capabilities may require future updates.

There is a problem with the instructions to install picamera2, it seems to create issues for the imx500 examples in https://github.com/raspberrypi/picamera2/tree/main/examples/imx500. Has it been tested with existing imx500 examples in the picamera2 repo?

git clone -b next https://github.com/raspberrypi/picamera2
cd picamera2 && pip install -e . --break-system-packages

Proper picamera2 installation is with apt, see https://github.com/raspberrypi/picamera2

[glenn-jocher]

@alexander-sony thank you for highlighting this. The installation via pip install -e . in the guide corresponds to the use of the development branch (next) in specific scenarios involving experimental features. For a stable installation, we recommend following the official picamera2 instructions using apt. We'll review the documentation to include clarifications on when each method should be used. Appreciate your feedback!

[glenn-jocher]

@alexander-sony the error indicates a mismatch between the input dimensions expected by the model and the data provided. Ensure the input image matches the expected size (default: 640x640) by resizing or specifying imgsz=640 during the export and prediction processes. Let me know if additional guidance is needed.
