More informative error message when string instead of list is passed to add_new_videos() #2463
Description
If you accidentally pass a string for video locations to add_new_videos() you get an uninformative error and DLC tries to slice the string.
Another side effect is that it creates a series of single-letter symlinks (for copy_videos=False) and a bunch of single-letter folders in the labelled-data folder.
Codes that causes the error:
import deeplabcut
config_file_path = "/gpfs/projects/acad/behavior/DLC_model/primary_DeepLabCut_model/LassanceLab-main-model-2023-09-14/config.yaml"
video_file_path = "/gpfs/projects/acad/behavior/videos/2023-11-13_conspecific_odor_videos/2023-09-15_test videos/Basler_acA1440-220um__40264738__20230912_112719915.mp4"
VideoType = 'mp4'
deeplabcut.add_new_videos(
config_file_path,
video_file_path,
copy_videos=True,
coords=None,
extract_frames=False,
)
