error:/opencv/modules/core/src/matrix.cpp:250: error: (-215:Assertion failed) s>=0 in function ‘setSize’

Using humble package may cause error:/opencv/modules/core/src/matrix.cpp:250: error: (-215:Assertion failed) s>=0 in function ‘setSize’,and when I compile humble packages I will get warning:

I tried opencv 4.5 and 4.8,warning and error still remain,how to solve this problem?

@AleDuz
The warning is because of the multiple versions of OpenCV in your device. You can ignore it if it does not create trouble. You can also uninstall your OpenCV version you installed on your PC before or after ROS installation
