I am wondering if there will be official support for YoloV9 on the tools.luxonis.com website. I was able to compile the ultralytics V9 weights using the V8 setting, but am wondering if there is "more official" support coming or if V9 is completely compatible with V8 settings. I could not find anything regarding V9 support on the forum/docs/etc. Thanks!

Hi @"justincdavis"#2876, that's a good question. Thank you for that! Yes, you are able to convert the YOLOv9 weights from Ultralytics using the YOLOv8 conversion option and then use the exported model on a camera without a problem (I verified it). We plan on improving this by updating the version detector and the docs to officially support the YOLOv9 from Ultralytics. Best Jan

@"JanCuhel"#p24749 Awesome thank you for the info!

Hi @"justincdavis"#2876, we've deployed an updated version of tools with the changes mentioned above, there's now a dedicated `YOLOv9` export option in tools. Here's how it looks like: [upl-image-preview url=https://discuss.luxonis.com/assets/files/2024-08-12/1723438745-125134-image.png] Best, Jan

Hi, Thank you for your deploying yolov9 export option! I exported Ultralytics yolov9t and applied it object tracking example (depthai-python\\examples\\ObjectTracker\\object_tracker.py) but failed to detect and tracing the object. There was no specific error however no bounding box and labels on the output view captured by OAK-D pro W PoE camera. Need help somebody to resolve problem.

Hi @"JungOscar"#2908, I'll look into it and get back to you as soon as possible! Best, Jan

Hi @"JungOscar"#2908, The reason why the `depthai-python\examples\ObjectTracker\object_tracker.py` example wasn't working for you is because the example was created for MobileNet-SSD model, so it uses `MobileNetDetectionNetwork` node from DepthAI, but for YOLO models you need to use `YoloDetectionNetwork`. We have another more suited experiment for your needs, and that is `gen2-deepsort-tracking` ([link](https://github.com/luxonis/depthai-experiments/tree/master/gen2-deepsort-tracking)), which uses the YOLOv6 model; however, if you place the `yolov9t.bin`, `yolov9t.xml`, and `yolov9t.json` files in the root folder of this app, and replace the[ line 32](https://github.com/luxonis/depthai-experiments/blob/master/gen2-deepsort-tracking/main.py#L32) of the `main.py` script `yolo = oak.create_nn('yolov6nr3_coco_640x352', input=color)` with this: `yolo = oak.create_nn('./yolov9t.json', input=color, nn_type='yolo')` Then it will work. Kind regards, Jan

Hi @"JanCuhel" Thank you for your support! I tested yolov9t model using the gen2-deepsort-tracking experimental app according as instructed and It worked successfully. Next, I tried using my custom YOLOvn-based model trained to detect “fish”. It seemed to work initially, but the app soom encountered the following error and stopped: [14442C101148F3D600] [59.19.225.203] [61.171] [ImageManip(8)] [error] Invalid configuration or input image - skipping frame [14442C101148F3D600] [59.19.225.203] [61.193] [ImageManip(8)] [error] Not possible to create warp params. Error: WARP_SWCH_ERR_CACHE_TO_SMALL This might not be related to an issue with exporting the NN. Any advice you could provide would be greatly appreciated. Best, Oscar

YoloV9 Support in tools.luxonis.com

JanCuhel

@JungOscar, could you please share your YOLO fish detection model with us and provide us with more info about your model, such as whether it is YOLOv9, whether you used our tools to export it, and, more importantly, what is the input image shape with which you exported the model? We'll take a closer look and get back to you.

Best,
Jan

Hi,

I have sent my model via email(support@loxonis.com). It is attached as a zip file named 'custom_yolo8n.zip'.

This model was initially built before the export tool supported YOLOv9, so I rebuilt it using YOLOv8 and exported it with your tool. The input image size is 640x640. You can find details about the dataset I used at this link: https://universe.roboflow.com/megaplanoscarjung/mackerel-ojdbq.

Thank you for your support and I would really appreciate it if you could take a closer look!

JanCuhel

JungOscar

thank you. I'll take a look and let you know as soon as I find something!

Kind regards,
Jan

I don't think there is a problem with the model.

JungOscar [14442C101148F3D600] [59.19.225.203] [61.171] [ImageManip(8)] [error] Invalid configuration or input image - skipping frame

[14442C101148F3D600] [59.19.225.203] [61.193] [ImageManip(8)] [error] Not possible to create warp params. Error: WARP_SWCH_ERR_CACHE_TO_SMALL

These two errors above are not related to NN. Could you add a MRE code so we can test locally?

Thanks,
Jaka

jakaskerl

JungOscar
The NN is quite complex and can only run at about 5FPS. The WARP_SWCH_ERR_CACHE_TO_SMALL is due to the big image size, there are 3 ImageManip nodes in the pipeline which all share resources. The bigger NN size maxes out these resources.

Consider using a smaller input size for NN.

Thanks,
Jaka

JanCuhel

@JungOscar, Yes, @jakaskerl is correct; the exported model is working (though it recognizes other objects as fish, it's not crashing). I wanted to check that it is. What is your goal? Do you need to set up a tracking pipeline, or is detection enough for you?

For testing an YOLO object detection model I used this experiment (link).

Best,
Jan

JungOscar

JanCuhel I don't understand your question, but just want to create applicaiton using cutom NN based on YOLO. I will follow your linked experimental guide next time.

JungOscar

jakaskerl I understand your points. I might need guidance on reducing input size for the neural network. Any documentation or sharing of experience or knowledge on this would be helpfull.

Thanks,

Oscar

Hi @JungOscar
I think since you are using YOLOv8, you can change the resolution on the fly when specifying the width/height in https://tools.luxonis.com.

I think that was the case for newer models, cc @JanCuhel to be sure.

Thanks,
Jaka

JungOscar

jakaskerl Hi,

I will change the resolution to a smaller width and height in tools.luxonis.com.

Thanks,

Oscar

JanCuhel

JungOscar

Yes, using a smaller width and height will definitely help, but more importantly, using a small model is essential. For RVC2, I'd encourage you to use the smallest YOLO variants (e.g., nano in the case of YOLOv5, v6, v8, v10; and t for YOLOv7 and YOLOv9)

Best,
Jan

takgoya

Hi,

What about supporting YOLOv9 custom weights, not just from official ultralytics weights?

I have tried converting my custom model and it does not work.

Thanks in advance.

Regards,

Javier.

JanCuhel

Hi @takgoya,

unfortunately, we currently support only the YOLOv9 weights from Ultralytics.

Best,
Jan

takgoya

Thanks for answering @JanCuhel .

Any plan on adding this in the future?

JanCuhel

takgoya

As far as I know, not in the foreseeing future, I am sorry about that. However, if anything would change, I'll let you know!

In the meantime, you could try to implement it yourself, good place to start would be to check this.

Kind regards,
Jan
