Dataset preparation

TODO make command for preparation dataset, see example

1. remove dups via apt install findimagedupes

   findimagedupes -R -i 'VIEW(){ for f in "$@";do echo $f;done }' -- /path/to/dataset/ | grep .txt -v | xargs -r -n 1 -I {} rm {}

2. Resize all image and convert to jpg via apt install imagemagick

   mogrify -resize 512x512 -format jpg -path /path/to/dataset_resized/ /path/to/dataset/
   cp /path/to/dataset/*.txt /path/to/dataset_resized/

3. Rename dataset_resized to format img/{reperats}_{instance_prompt} {class_prompt} for kohya_ss.
   as example:

   • repeats - 40
   • instance prompt masabodo ? TODO check docs
   • class prompt 1girl ? TODO check docs

   folder name must be img/40_masabodo 1girl - it is image folder for kohya_ss
