[Tutorial + Tool] Caption files for Flux training [SFW + NSFW]

[Tutorial + Tool] Caption files for Flux training [SFW + NSFW]

I've created a simple captioning script that runs the Joy-Caption script on all files in a folder.

https://github.com/MNeMoNiCuZ/joy-caption-batch

Examples:

Joy-Caption - Batch

This tool utilizes the Joy-Caption tool (still in Pre-Alpha), to caption image files in a batch.

Place all images you wish to caption in the /input directory and run py batch.py.

Setup

  1. Git clone this repository git clone https://github.com/MNeMoNiCuZ/joy-caption-batch/

  2. (Optional) Create a virtual environment for your setup. Use python 3.9 to 3.11. Do not use 3.12. Feel free to use the venv_create.bat for a simple windows setup. Activate your venv.

  3. Run pip install -r requirements.txt (this is done automatically with the venv_create.bat).

  4. Install PyTorch with CUDA support matching your installed CUDA version. Run nvcc --version to find out which CUDA is your default.

Low VRAM Mode

Now supports LOW_VRAM_MODE=true. Edit this line in the batch.py-file.

This will use a llama3-8b-bnb-4bit quantized version from unsloth

Requirements

Tested on Python 3.10 and 3.11.

Tested on Pytorch w. CUDA 12.1.

Original app and source on huggingface.

WARNING:

This is just a captioning tool. This may not be the best way to train Flux models. We don't know

the best practices yet. See the conversation in the discussion below.
