[svo-1] process has died [pid 3794, exit code -6

[suntttabc]

Hi, I used ubantu 20 and ROS nietic to run the code, and the following problems occurred.

1. SVO stays at the first frame initialization
   2、alled after throwing an instance of 'cv::Exception'
   what(): OpenCV(4.5.5-dev) /home/sly/opencv_ build/opencv/modules/core/src/matrix. cpp:246: error: (-215:Assertion failed) s >= 0 in function 'setSize
   '[svo-1] process has died [pid 3794, exit code -6
   Can someone help me look at this problem? Thank you very much
