datasets:
# datasets are a folder of images. captions need to be txt files with the same name as the image
# for instance image2.jpg and image2.txt. Only jpg, jpeg, and png are supported currently

# on windows, escape back slashes with another backslash so

# control path is the input images for kontext for a paired dataset. These are the source images you want to change.
# You can comment this out and only use normal images if you don't have a paired dataset.
# Control images need to match the filenames on the folder path but in
# a different folder. These do not need captions.
