Value Error generating grid movies

[lencriv]

I am receiving the following error when attempting to generate grid movies. I saw that this was an issue for crowd movies and was fixed in the most recent release (crowd movies do not produce this error for me).

Thanks for the heads up! I'll fix this going forward. In the meantime you can avoid it by passing in an explicit window_size, e.g.

kpms.generate_grid_movies(name=name, project_dir=project_dir, coordinates=coordinates, window_size=240, **config())

I published the fix (https://github.com/dattalab/keypoint-moseq/releases/tag/0.1.3) so now updating should solve the problem.
