I’m very happy to share my LoRA Caption workflow for ComfyUI that will let you run a batch of images through two different captioning methods using Florence 2 model or using Clip Interrogator. Both these are paired with WD14 Tagger node which generates some additional tags/keywords for the caption.
Images must be PNG format, JPEGs are not supported currently in the workflow due to custom node.
You can enter the LoRA training “trigger” word which is added to the prompt.
Useful tips
- Caption files generated cannot be overwritten – this a limitation of the custom node, if you want to re-run delete the original TXT file
- Once all images are run through you need to Reset the counter. Use the Reset counter (use once) switch – set to true. Remember to turn if off – set to false.
- List index out of range error – this means you are trying to run it but the txt file caption already exists. Or the counter has reached its limit, you need to reset it.
- I always recommend that you review the captions and finetune them to ensure you get the best result out of your LoRA.
