Model convert from https://github.com/KichangKim/DeepDanbooru

Usage:

import cv2
import numpy as np
import onnxruntime as rt
from huggingface_hub import hf_hub_download

tagger_model_path = hf_hub_download(repo_id="skytnt/deepdanbooru_onnx", filename="deepdanbooru.onnx")

tagger_model = rt.InferenceSession(tagger_model_path, providers=['CUDAExecutionProvider', 'CPUExecutionProvider'])

        image = img_new[np.newaxis, :]
        probs = tagger_model.run(None, {"input_1": image})[0][0]
        probs = probs.astype(np.float32)
        res = []
