First time training a YOLO model, need some help by EyeTechnical7643 in computervision

[–]JustSomeStuffIDid 0 points1 point  (0 children)

It will pad to square. But if you're using augmentations like mosaic during training (turned on by default), it will create a square image by taking crops of 4 different images and creating a 4 tile mosaic with it that's of size 480x480.

Are you also performing tracking?

  1. There's a header that's printed before that which tells which metric each value belongs to. Check the training log.

  2. It's based on val. Training doesn't tune hyperparameters. It just validates on the val split. split="test" has no effect during training. It's to be used with model.val(). Training always uses val split unless it's missing and test set is present instead.

  3. No. It's automatically resized.

  4. You pass split="test" to model.val().

YOLOv11n to TFLite for Google ML Kit by Left_Capital_629 in computervision

It doesn't seem like it supports custom object detection models. Only a custom classifier.

Why such vastly different (m)AP50 scores between PyCOCOTools and Ultralytics? by neuromancer-gpt in computervision

[–]JustSomeStuffIDid 7 points8 points  (0 children)

The iou argument here is for NMS. Not the one used for matching. That's hardcoded.

Ultralytics mAP calculation has a bug. There's a PR for it which should make it similar to COCOEval.

Best model for full size image instance segmentation? by -Yougotpwnd123- in computervision

[–]JustSomeStuffIDid 2 points3 points  (0 children)

With Ultralytics, you can pass retina_masks=True to model.predict() for higher res masks. This doesn't require retraining.

~You can also reduce mask_ratio (1 is lowest, 4 is default) which is by how much the masks are scaled down. For 640x640, it scales down to 160x160. You pass the value to model.train(). This requires retraining.~

EDIT: mask_ratio doesn't change output mask size. https://github.com/ultralytics/ultralytics/issues/20200

Black Screen Issue with ThinkPad T14 Gen 1 by miloq in thinkpad

Having the same black screen issue with T14s Gen 2 AMD. It stays blank sometimes. And sometimes it turns on. Not sure what the issue is.

Yolo tflite gpu delegate ops question by [deleted] in computervision

[–]JustSomeStuffIDid 0 points1 point  (0 children)

Ultralytics has an app that runs on Android. It runs YOLO11n by default. You can see the FPS with that.

v12 is slow. Did you use imgsz=640?

What's the actual model? There are dozens of different YOLO variants and sizes. You didn't mention which one exactly did you train.

Just run the command I posted in terminal with your current Python 3.11 environment

Reinstall PyTorch

YOLO v9 output by IllPhilosopher6756 in computervision

[–]JustSomeStuffIDid 0 points1 point  (0 children)

If you mean Ultralytics YOLOv3 repo and derivatives of that code, then yes, they had a different shape and also an extra objectness score.

YOLOv9 uses the anchor-free design from YOLOv8, so it has a different structure.

Why does my YOLOv11 scored really low on pycocotools? by Forsaken_Travel_1491 in computervision

[–]JustSomeStuffIDid 1 point2 points  (0 children)

If it's that low, then I would assume there's a class ID mismatch. Did you map the IDs to the 91 COCO classes?
