Hello @matsuoka
More info about YOLO v5 could be found here - https://github.com/ultralytics/yolov5
Microsoft currently has no official docs about YOLO v5 but you can surely use it in Azure environment as guidance above. I will reach out to product team to see how we can leverage YOLO v5 more but please let us know if you have more question during the time you working on your project.
Regards,
