cv2.dnn.readNet fail

[Xuagent]

cv2.error: OpenCV(4.4.0) C:\Users\appveyor\AppData\Local\Temp\1\pip-req-build-1hg9yufe\opencv\modules\dnn\src\onnx\onnx_importer.cpp:1410: error: (-2:Unspecified error) in function
'void __cdecl cv::dnn::dnn4_v20200609::ONNXImporter::populateNet(class cv::dnn::dnn4_v20200609::Net)'

(expected: 'shapes.depth() == CV_32S'), where
'shapes.depth()' is 5 (CV_32FC1)
must be equal to
'CV_32S' is 4 (CV_32SC1)

What could be the reason for this? and how to fix it？
my opencv-python==4.4.0.40
Thanks

你是用的opencv版本低了，升级opencv到最新版本再运行程序试试
