I got an error when rosrun darknet_ros darknet_ros

Hi, I followed all through "README", but I still got an error like this :

[ INFO] [1558455233.638429916]: [YoloObjectDetector] Node started.
[ INFO] [1558455233.640436069]: [YoloObjectDetector] Xserver is running.
[ INFO] [1558455233.640764302]: [YoloObjectDetector] init().
YOLO V3
Couldn't open file: /default/yolov2-tiny.cfg

when I execute "rosrun darknet_ros darknet_ros" on terminal even though I have already downloaded yolov2-tiny.weights files and had .cfg files in cfg folder. What should I do? Any held will be helpful.

try roslaunch instead of rosrun
