Hi all, I am using Ubuntu 18.04 and my OpenCV version is 4.1.1. When I want to roslaunch I get the error like this:
OpenCV Error: Bad argument (Invalid pointer to file storage) in cvGetRootFileNode, file /build/opencv-XDqSFW/opencv-3.2.0+dfsg/modules/core/src/persistence.cpp, line 926
terminate called after throwing an instance of 'cv::Exception'
what(): /build/opencv-XDqSFW/opencv-3.2.0+dfsg/modules/core/src/persistence.cpp:926: error: (-5) Invalid pointer to file storage in function cvGetRootFileNode
Does anyone know how to solve this error?
