CXH_Min2_6_classifiy

CXH_Min2_6_classifiy (note the author's spelling - "classifiy") is the pack's batch image classifier: it walks a folder of images, asks MiniCPM-V 2.6 to categorize each one, and copies it into a per-category subfolder under your save_dir. Added in late 2024 per the README's changelog, it's a dataset-organization tool, not a captioner - you'd use it before captioning, to split a mixed pile of reference images into clean per-class training folders.

The default prompt is a fashion-image classifier: it sorts clothing photos into MAN or WoMAN folders by priority order, and demands a specific output format (a bare [CATEGORY_NAME] in caps, nothing else). That's the author's own use case, but the prompt is fully editable - you can redefine the categories to anything the model can label ("landscape|portrait|product", "photo|art|screenshot", whatever).

How it works

For every image it runs the MiniCPM-V chat API with the image plus your classification instructions, takes the model's reply as a category name, strips any surrounding brackets, and creates/copies the image into save_dir/<category>/. Two safety valves in the source:

• If the reply is over 80 characters it's treated as a failure and filed under UNKNOWN (protects against the model rambling instead of answering).
• Original filenames are preserved, so you can trace every file back.

There are no outputs - this is an OUTPUT_NODE; the results are the folders it creates. It prints progress (n/total: X.XXXs) to the console.

Inputs

• pipe - from CXH_HG_Model_Load (MiniCPM-V 2.6).
• img_dir - source folder of images.
• save_dir - destination; category subfolders get created here.
• prompt - the classification rules (default: the fashion MAN/WoMAN rules).
• format - png or jpg for the copied files (jpg converts RGBA → RGB automatically).
• max_tokens, temperature, seed - generation controls.

Installing

Pack install - ComfyUI Manager (search "Comfyui_CXH_joy_caption") or:

cd ComfyUI/custom_nodes
git clone https://github.com/StartHua/Comfyui_CXH_joy_caption
cd Comfyui_CXH_joy_caption
python -m pip install -r requirements.txt

Gotchas

• Category names become folder names, so keep them filesystem-safe (no /, no trailing dots). The default prompt's [CATEGORY_NAME] format exists precisely so the folder names come out clean.
• It copies, it doesn't move - your originals stay put. Free, just disk-hungry on big folders.
• The MAN/WoMAN default is two-category. Add your own categories to the prompt's rules and the model will use them; just keep the "output only the category name" instruction intact or the UNKNOWN bucket fills up.
• Misspelled node name: it's CXH_Min2_6_classifiy (class-i-f-i-y). Search for "classifiy" in ComfyUI Manager, not "classify".
• NVIDIA-friendly like the rest of the MiniCPM route; expects a GPU.
