Multi-task YOLO26 parallel pipeline on Metis Compute Board

Hi ​@kmiura !

Voyager 1.6 does work fine on the MCB, yep. Although you’re right that the user manual (issue 2) needs a refresh 👍  The v1.6 release notes on GitHub are the current reference in the meantime.

All four YOLO26 tasks (OD, pose, seg, OBB) are in the 1.6 model zoo. The cleanest way to run them together on one USB camera is a parallel YAML pipeline. I think this might be a good test, if you swap the YOLO11 entries for the YOLO26 YAMLs: https://github.com/axelera-ai-hub/voyager-sdk/blob/latest/ax_models/reference/parallel/parallel-yolo11-pose-seg-retinaface.yaml

And the parallel/cascade pattern is documented here: https://github.com/axelera-ai-hub/voyager-sdk/blob/latest/docs/tutorials/application.md

Let me know how it goes with those! I’d love to see this in action when you do it 👍

Thank you for your reply.
I was able to obtain the performance results attached by referring to the user guide and quick_start_guide.
First, I'm thinking of using multiple_pipelines.py from Examples:.
I'm getting an error and can't run ’multiple_pipelines.py usb:0’.
How should I enter the command?
Thank you in advance.

Hi, Spanner!

When I run the attached YAML file, I get an error.

Thank you for your assistance.

Hi ​@kmiura!

Could this be the swap from YOLO11 to YOLO26? I’m going from memory here so I might not be bang on, but if the weight_url is causing the 403 and the md5 is still the YOLO11 hash, I don’t think that’d match the YOLO26 weights. If that makes sense?

So if you have a look in ax_models/zoo/yolo/ and dig out the YOLO26 YAMLs, copy the weight_url, weight_md5 and weight_path fields from those into your parallel YAML, then try running again?

Let me know if that makes sense, and/or if it helps!

Hello Spanner!

I copied the weight_url, weight_md5, and weight_path fields into the YOLO26 YAML file.

I'm still getting errors.

Hmm, that looks like a different issue now, doesn’t it? Looks like the compiler itself is hitting a limit on the yolo26nseg model, perhaps.

A couple of tests come to mind the we could try:

• Can you confirm yolo26nseg works on its own first? Just run ./inference.py yolo26nseg-coco-onnx media/traffic1_1080p.mp4. That'll tell us whether yolo26-seg is the problem, or whether it's specifically yolo26-seg inside a parallel pipeline that's the issue.
• I wonder if YOLO11 is worth a test, too? It’s got pose, seg, obb and is well established. Even if just for disgnostic purposes?

Let me know what comes back!

(Oh, by the way - I thought it’d be easier for us to keep track of the conversation if I promoted it to its own topic! So I’ve moved everything out of the blog’s comments and into here 😀)

Hi, Spanner!

’./inference.py yolo26nseg-coco-onnx media/traffic1_1080p.mp4’’

It seems there are no problems.

I'll consider using YOLO11 for now.

Thank you.
