Thanks for your work! When I run the elg_train.py, it works perfect util step (about) 075000.
when i meet this error, sometimes, it can work continue or just stop after work 4-6 steps. Looking forward to your reply.

Hi could you check if the issue still exists with branch cvlineaug_fix (https://github.com/swook/GazeML/tree/cvlineaug_fix)?

Thanks!

Thanks for reply ! I print the value of 6*line_rand_nums[j + 4]。When value < 1, it reports an error。I just change the unityeyes.py（lines 237)
t = int(6*line_rand_nums[j + 4]) if t < 1 : t = 1 eye = cv.line(eye, (lx0, ly0), (lx1, ly1), color=(line_colour, line_colour, line_colour), thicknesss = t, lineType = cv.LINE_AA)
Then, it can work without error. Apparently, your code is more pithy .
