for example :PaddleOCR-develop/doc/imgs/11.jpg
when i run the code"sh tools/run.sh",that output: "terminate called after throwing an instance of 'cv::Exception' what(): OpenCV(3.4.7) /home/wz/Downloads/opencv-3.4.7/modules/imgproc/src/convhull.cpp:137: error: (-215:Assertion failed) total >= 0 && (depth == CV_32F || depth == CV_32S) in function 'convexHull' "

can you tell me how to change?
