## How to Get Started with the Model
|
18 |
+
|
19 |
+
```python
|
20 |
+
from transformers import VisionEncoderDecoderModel,AutoTokenizer, TrOCRProcessor
|
21 |
+
import torch
|
22 |
+
from PIL import Image
|
23 |
+
|
24 |
+
|
25 |
+
device = torch.device('cuda') # change 'cuda' if you need.
|
26 |
+
|
27 |
+
image_path='(your image path)'
|
28 |
+
image = Image.open(image_path)
|
29 |
+
#model can be .jpg or .png
|

|
33 |
+
trocr_model = "gg4ever/trOCR-youtube-kor-OCR"
|
34 |
+
model = VisionEncoderDecoderModel.from_pretrained(trocr_model).to(device)
|
35 |
+
tokenizer = AutoTokenizer.from_pretrained(trocr_model)
|
36 |
+
|
37 |
+
pixel_values = (processor(image, return_tensors="pt").pixel_values).to(device)
|
38 |
+
generated_ids = model.generate(pixel_values)
|
39 |
