$ yolov5 train -data coco.yaml -cfg yolov5s.yaml -weights '' -batch-size 64 Use the largest -batch-size your GPU allows (batch sizes shown for 16 GB devices). Training times for YOLOv5s/m/l/x are 2/4/6/8 days on a single V100 (multi-GPU times faster). Run commands below to reproduce results on COCO dataset (dataset auto-downloads on first use). You can call yolov5 train, yolov5 detect, yolov5 val and yolov5 export commands after installing the package via pip: Training run ( source = img_url, weights = "yolov5s6.pt", conf_thres = 0.25, imgsz = 640 )

run ( imgsz = 640, weights = 'yolov5s.pt' )įrom yolov5 import detect img_url = '' detect. run ( imgsz = 640, data = 'coco128.yaml', weights = 'yolov5s.pt' ) detect. run ( imgsz = 640, data = 'coco128.yaml' ) val.

You can directly use these functions by importing them:įrom yolov5 import train, val, detect, export train.
