原因:opencv-python 的版本更新影响

在这里插入图片描述

    cv2.drawMarker(image_sgl, (x_co, y_co), (int(color[0]), int(color[1]), int(color[2])), marker_type, 8, thickness = 3)
cv2.error: OpenCV(4.6.0) :-1: error: (-5:Bad argument) in function 'drawMarker'
> Overload resolution failed:
>  - Can't parse 'position'. Sequence item with index 0 has a wrong type
>  - Can't parse 'position'. Sequence item with index 0 has a wrong type

我原本的版本是4.6.0.66,需要下降版本到4.5.1.48

 pip install opencv-python==4.5.1.48 -i https://pypi.douban.com/simple
