Model description

This model is an experimental model that predicts danbooru tags of images.

Example

Use a pipeline

from transformers import pipeline

pipe = pipeline("image-classification", model="p1atdev/siglip-tagger-test-3", trust_remote_code=True)
pipe(
  "image.jpg", # takes str(path) or numpy array or PIL images as input
  threshold=0.5, #optional parameter defaults to 0
  return_scores = False #optional parameter defaults to False
)

• threshold: confidence intervale, if it's specified, the pipeline will only return tags with a confidence >= threshold
• return_scores: if specified the pipeline will return the labels and their confidences in a dictionary format.

Load model directly

from PIL import Image
import torch

from transformers import (
    AutoModelForImageClassification,
    AutoImageProcessor,
)

import numpy as np

MODEL_NAME = "p1atdev/siglip-tagger-test-3"

model = AutoModelForImageClassification.from_pretrained(
    MODEL_NAME, torch_dtype=torch.bfloat16, trust_remote_code=True
)
model.eval()
processor = AutoImageProcessor.from_pretrained(MODEL_NAME)

image = Image.open("sample.jpg") # load your image

inputs = processor(image, return_tensors="pt").to(model.device, model.dtype)

logits = model(**inputs).logits.detach().cpu().float()[0]
logits = np.clip(logits, 0.0, 1.0)

results = {
    model.config.id2label[i]: logit for i, logit in enumerate(logits) if logit > 0
}
results = sorted(results.items(), key=lambda x: x[1], reverse=True)

for tag, score in results:
    print(f"{tag}: {score*100:.2f}%")

Intended uses & limitations
