- ## Usage
29
- Inference using Huggingface transformers on NVIDIA GPUs. Requirements tested on python 3.10:
30
- ```
31
- torch==2.0.1
32
- torchvision==0.15.2
33
- transformers==4.37.2
34
- tiktoken==0.6.0
35
- verovio==4.3.1
36
- accelerate==0.28.0
37
- ```
38
-
39
-
40
- ```python
41
- from transformers import AutoModel, AutoTokenizer
42
-
43
- tokenizer = AutoTokenizer.from_pretrained('ucaslcl/GOT-OCR2_0', trust_remote_code=True)
44
- model = AutoModel.from_pretrained('ucaslcl/GOT-OCR2_0', trust_remote_code=True, low_cpu_mem_usage=True, device_map='cuda', use_safetensors=True, pad_token_id=tokenizer.eos_token_id)
45
- model = model.eval().cuda()
46
-
47
-
48
- # input your test image
49
- image_file = 'xxx.jpg'
50
-
51
- # plain texts OCR
52
- res = model.chat(tokenizer, image_file, ocr_type='ocr')
53
-
54
- # format texts OCR:
55
- # res = model.chat(tokenizer, image_file, ocr_type='format')
56
-
57
- # fine-grained OCR:
58
- # res = model.chat(tokenizer, image_file, ocr_type='ocr', ocr_box='')
59
- # res = model.chat(tokenizer, image_file, ocr_type='format', ocr_box='')
60
- # res = model.chat(tokenizer, image_file, ocr_type='ocr', ocr_color='')
61
- # res = model.chat(tokenizer, image_file, ocr_type='format', ocr_color='')
62
-
63
- # multi-crop OCR:
64
- # res = model.chat_crop(tokenizer, image_file, ocr_type='ocr')
65
- # res = model.chat_crop(tokenizer, image_file, ocr_type='format')
66
-
67
- # render the formatted OCR results:
68
- # res = model.chat(tokenizer, image_file, ocr_type='format', render=True, save_render_file = './demo.html')
69
-
70
- print(res)
