# trOCR-youtube-kor-OCR |
|
|
|
fine-tuned for VisionEncoderDecoderModel(encoder , decoder) |
|
encoder = 'facebook/deit-base-distilled-patch16-384' |
|
decoder = 'klue/roberta-base' |
|
|
|
## How to Get Started with the Model |
|
|
|
```python |
|
from transformers import VisionEncoderDecoderModel,AutoTokenizer, TrOCRProcessor |
|
import torch |
|
from PIL import Image |
|
|
|
|
|
device = torch.device('cuda') # change 'cuda' if you need. |
|
|
|
image_path='(your image path)' |
|
image = Image.open(image_path) |
|
#model can be .jpg or .png |
|
#hugging face download: https://huggingface.co/gg4ever/trOCR-final |
|
|
|
processor = TrOCRProcessor.from_pretrained("microsoft/trocr-base-handwritten") |
|
trocr_model = "gg4ever/trOCR-youtube-kor-OCR" |
|
model = VisionEncoderDecoderModel.from_pretrained(trocr_model).to(device) |
|
tokenizer = AutoTokenizer.from_pretrained(trocr_model) |
|
|
|
pixel_values = (processor(image, return_tensors="pt").pixel_values).to(device) |
|
generated_ids = model.generate(pixel_values) |
|
generated_text = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0] |
|
print(generated_text) |
|
|
|
``` |
