+
+## Usage
+Inference using Huggingface transformers on NVIDIA GPUs. Requirements tested on python 3.10：
+```
+torch==2.0.1
+torchvision==0.15.2
+transformers==4.37.2
+tiktoken==0.6.0
+verovio==4.3.1
+accelerate==0.28.0
+```
+
+
+```python
+from transformers import AutoModel, AutoTokenizer
+
+tokenizer = AutoTokenizer.from_pretrained('ucaslcl/GOT-OCR2_0', trust_remote_code=True)
+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)
+model = model.eval().cuda()
+
+
+# input your test image
+image_file = 'xxx.jpg'
+
+# plain texts OCR
+res = model.chat(tokenizer, image_file, ocr_type='ocr')
+
+# format texts OCR:
+# res = model.chat(tokenizer, image_file, ocr_type='format')
+
+# fine-grained OCR:
+# res = model.chat(tokenizer, image_file, ocr_type='ocr', ocr_box='')
+# res = model.chat(tokenizer, image_file, ocr_type='format', ocr_box='')
+# res = model.chat(tokenizer, image_file, ocr_type='ocr', ocr_color='')
+# res = model.chat(tokenizer, image_file, ocr_type='format', ocr_color='')
+
+# multi-crop OCR:
+# res = model.chat_crop(tokenizer, image_file, ocr_type='ocr')
+# res = model.chat_crop(tokenizer, image_file, ocr_type='format')
+
+# render the formatted OCR results:
+# res = model.chat(tokenizer, image_file, ocr_type='format', render=True, save_render_file = './demo.html')
+
+print(res)
+
+
+```
