如何使用

• 安装 yolov5 :

pip install -U yolov5

• 加载模型并进行预测:

import yolov5

# load model
model = yolov5.load('keremberke/yolov5m-nfl')
  
# set model parameters
model.conf = 0.25  # NMS confidence threshold
model.iou = 0.45  # NMS IoU threshold
model.agnostic = False  # NMS class-agnostic
model.multi_label = False  # NMS multiple labels per box
model.max_det = 1000  # maximum number of detections per image

# set image
img = 'https://github.com/ultralytics/yolov5/raw/master/data/images/zidane.jpg'

# perform inference
results = model(img, size=640)

# inference with test time augmentation
results = model(img, augment=True)

# parse results
predictions = results.pred[0]
boxes = predictions[:, :4] # x1, y1, x2, y2
scores = predictions[:, 4]
categories = predictions[:, 5]

# show detection bounding boxes on image
results.show()

# save results into "results/" folder
results.save(save_dir='results/')

• 在自定义数据集上进行微调:

yolov5 train --data data.yaml --img 640 --batch 16 --weights keremberke/yolov5m-nfl --epochs 10
