Args Used

Basic args

• --K_train: type=int, argtype=static. The number of multiple generations when training. This arg only works for multiple-generation models. The default value is 10.

• --draw_distribution (short for -dd): type=int, argtype=temporary. Controls if draw distributions of predictions instead of points. If draw_distribution == 0, it will draw results as normal coordinates; If draw_distribution == 1, it will draw all results in the distribution way, and points from different time steps will be drawn with different colors. The default value is 0.
• --draw_exclude_type (short for -det): type=str, argtype=temporary. Draw visualized results of agents except user-assigned types. If the assigned types are "Biker_Cart" and the draw_results or draw_videos is not "null", it will draw results of all types of agents except "Biker" and "Cart". It supports partial match and it is case-sensitive. The default value is null.
• --draw_extra_outputs: type=int, argtype=temporary. Choose whether to draw (put text) extra model outputs on the visualized images. The default value is 0.

• --draw_videos: type=str, argtype=temporary. Controls whether draw visualized results on video frames and save as images. Accept the name of one video clip.
