YOLOv8 dfl_loss metric
I was wondering how to interpret different losses in the YOLOv8 model. I've easily found explanations about the box_loss and the cls_loss. About the dfl_loss I don't find any information on the Internet. I've also checked the YOLOv8 Docs.
I've found…

Loading YOLO8 in pytorch nn.module
I have trained a yolov8n and now need to do inferences using pytorch, but I don't know how to properly import/convert the layers to load.
I can make predictions in YOLO using model.predict(), but I need to load this like in pytorch format.
If I…

How to freeze the backbone, feature extraction layers, in YOLO v8
I want to train the YOLO v8 in transfer learning on my custom dataset.
I have different classes than the base training on the COCO dataset.
Yet I don't want to learn again the feature extraction.
Hence I though following the Ultralytics YOLOv8 Docs…

How to interpret output tensor from YOLOv8 web model?
I am using YOLOv8 for object detection in a React app, and I'm having trouble interpreting the output of the model. I have taken the official "yolov8n.pt" model from Ultralytics and converted it to a web model in python like this:
model =…

YoloV8 Label file when there is no bounding box?
I wanted to train my yolo model and see if I can detect pneumonia in images
So the images I have of X ray and the one which has pneumonia , its labels look like the following

why yolov8 uses torch.zeros(1, ch, s, s) as input to forward pass to calculate model stride?
This is part of task.py from yolov8 codebase.
m = self.model[-1] # Detect()
if isinstance(m, (Detect, Segment, Pose)):
s = 256 # 2x min stride
m.inplace = self.inplace
forward = lambda x: self.forward(x)[0] if isinstance(m, (Segment, Pose)) else…

why torchsummary and torchinfo give different number of total parameter?
I am testing this code, to compare model parameters, which will help me to modify the models/layers, but I don't know which method gives me the actual number of parameters.
from torchsummary import summary

Yolov8: imgsz in predict()
What is the use of imgsz in inference on Yolov8 model ?
Looking at current documentation's example, we can write :
model.predict(source, save=True, imgsz=320, conf=0.5)
(https://docs.ultralytics.com/modes/predict/#inference-sources).
It is not…
