# 使用方法： |
|
```python |
|
from transformers import AutoTokenizer, VisionEncoderDecoderModel, AutoImageProcessor |
|
from PIL import Image |
|
import requests |
|
|
|
feature_extractor = AutoImageProcessor.from_pretrained("lrqlrqlrq/MixTex_Tiny_ZhEn_Latex_Math_OCR") |
|
tokenizer = AutoTokenizer.from_pretrained("lrqlrqlrq/MixTex_Tiny_ZhEn_Latex_Math_OCR", max_len=296) |
|
model = VisionEncoderDecoderModel.from_pretrained("lrqlrqlrq/MixTex_Tiny_ZhEn_Latex_Math_OCR") |
|
|
|
imgen = Image.open(requests.get('https://cdn-uploads.huggingface.co/production/uploads/62dbaade36292040577d2d4f/eOAym7FZDsjic_8ptsC-H.png', stream=True).raw) |
|
#imgzh = Image.open(requests.get('https://cdn-uploads.huggingface.co/production/uploads/62dbaade36292040577d2d4f/m-oVg8dsQbQZ1fDWbwKtO.png', stream=True).raw) |
|
print(tokenizer.decode(model.generate(feature_extractor(imgen, return_tensors="pt").pixel_values)[0]).replace('\\[','\\begin{align*}').replace('\\]','\\end{align*}')) |
|
``` |
