## Usage
```python
from transformers import VisionEncoderDecoderModel, TrOCRProcessor
import torch
from PIL import Image
# Load model and processor
processor = TrOCRProcessor.from_pretrained("anuashok/ocr-captcha-v2")
model = VisionEncoderDecoderModel.from_pretrained("anuashok/ocr-captcha-v2")
# Load image
image = Image.open('path_to_your_image.jpg').convert("RGB")
# Prepare image
pixel_values = processor(image, return_tensors="pt").pixel_values
# Generate text
generated_ids = model.generate(pixel_values)
generated_text = processor.batch_decode(generated_ids, skip_special_tokens=True)[0]
print(generated_text) |
