Yolov8_Efficient

Simple and efficient use for yolov8

About

This is an unofficial repository maintained by independent developers for learning and communication based on the ultralytics v8 Weights and ultralytics Project. If you have more questions and ideas, please feel free to discuss them together. In addition, if ultralytics releases the latest yolov8 warehouse, it is suggested to give priority to the official one.

1. CLI

To simply use the latest Ultralytics YOLO models

yolo task=detect    mode=train    model=yolov8n.yaml      args=...
          classify       predict        yolov8n-cls.yaml  args=...
          segment        val            yolov8n-seg.yaml  args=...
                         export         yolov8n.pt        format=onnx

2. Python SDK

To use pythonic interface of Ultralytics YOLO model

from ultralytics import YOLO

model = YOLO("yolov8n.yaml")  # create a new model from scratch
model = YOLO(
    "yolov8n.pt"
)  # load a pretrained model (recommended for best training results)
results = model.train(data="coco128.yaml", epochs=100, imgsz=640, ...)
results = model.val()
results = model.predict(source="bus.jpg")
success = model.export(format="onnx")

If you're looking to modify YOLO for R&D or to build on top of it, refer to Using Trainer Guide on our docs.

Usage

Train

Single-GPU training:

python train.py --data coco128.yaml --weights weights/yolov8ns.pt --img 640  # from pretrained (recommended)

python train.py --data coco128.yaml --weights '' --cfg yolov8ns.yaml --img 640  # from scratch

Use IDE Pycharm

Multi-GPU DDP training:

    python -m torch.distributed.run --nproc_per_node 4 --master_port 1 train.py --data coco128.yaml --weights yolov8ns.pt --img 640 --device 0,1,2,3

detect

python detect.py --weights yolov8s.pt --source 0                               # webcam
