Hello all, I am kind of new here. I tried to follow the lectures to the letter and also create a copy on offline using ROS - Kinetic on Ubuntu 16.04. here are some issues I am having with the lectures. I ran the rosrun my_following_line_package follow_line_step_hsv.py but I am experiencing this error:
File “/home/user/catkin_ws/src/my_following_line_package/scripts/follow_line_step_hsv.py”, line33, in camera_callback
crop_img = cv_image[(height)/2+descentre:(height)/2+(descentre+rows_to_watch)][1:width]
TypeError: slice indices must be integers or None or have an index method.
Also, is it possible to access and download the project models and launch files. I will like to practice more after I exhaust my daily hours especially during bad network connection which I am currently experiencing.
