clip-product-title-chinese

基于有赞商品图片和标题语料训练的clip模型。

Usage

使用模型前,请 git clone https://github.com/youzanai/trexpark.git

import torch
from src.clip.clip import ClipProcesserChinese, ClipChineseModel
import requests
from PIL import Image

clip_processor = ClipProcesserChinese.from_pretrained('youzanai/clip-product-title-chinese')
model = ClipChineseModel.from_pretrained('youzanai/clip-product-title-chinese')

url = 'http://img.yzcdn.cn/upload_files/2015/04/21/0140dac4657f874f2acff9294b28088c.jpg'
img = Image.open(requests.get(url, stream=True).raw).convert('RGB')
imgs = [img]
texts = ['运动鞋', '红色连衣裙', '黑色连衣裙', '大衣', '文具']

f = clip_processor(texts, imgs, return_tensors='pt', truncation=True, padding=True)
del f['token_type_ids']
with torch.no_grad():
    out = model(**f)
logits_per_image, logits_per_text = out['logits_per_image'], out['logits_per_text']

print(logits_per_image.softmax(dim=-1).cpu().detach().numpy())
