Guess it is not detecting a line then give up :)

AssertionError: Not enough valid windows to create a fit.

Hello, I'm a student and interested your project.
When I use the "find_lane.py", I got mistakes.
The Error is "assert len(win_left_valid) >= 3 and len(win_right_valid) >= 3, 'Not enough valid windows to create a fit.'"
I check the code, and find that when the function "filter_window_list" ( which is in windows.py) work, all variable of window.dropped, window.frozen, window.detected are True, and it makes all windows can not be appended in variable "windows_filtered".
Although, there is tips " # TODO: Do something if not enough windows to fit. Most likely fall back on old measurements." in "find_lane.py", I do not know how to fix it. Can you help me? Thank you !

Followed your installation instruction. But got this import package error "dot3" from filterpy.kalman.
I search the filterpy.kalman codes, only dot is supported.
Thanks for looking into this.
Tac.

In line 339 of windows.py, what's the meaning of 0.5 for velocity? I change it to 0.0 and the result seems not changed?
