yolov4 tutorials : error when running test_video_yolov4

[theo06v]

Hello,
I am currently doing the tutorial to deploy yolov4 on ZCU104 using tensorflow. When I execute the command ./test_video_yolov4 dpu_yolov4 0 -t4, this is the error I get. Do you have any idea why I get this error? Moreover, I use the See3CAM camera but I also tried with another camera that I managed to make work with openCV and I got the same error.
