# Usage
```python
from PIL import Image
import numpy as np
from transformers import AutoModel
import torch

model = AutoModel.from_pretrained("ragavsachdeva/magiv2", trust_remote_code=True).cuda().eval()


def read_image(path_to_image):
    with open(path_to_image, "rb") as file:
        image = Image.open(file).convert("L").convert("RGB")
        image = np.array(image)
    return image

chapter_pages = ["page1.png", "page2.png", "page3.png" ...]
character_bank = {
    "images": ["char1.png", "char2.png", "char3.png", "char4.png" ...],
    "names": ["Luffy", "Sanji", "Zoro", "Ussop" ...]
}

chapter_pages = [read_image(x) for x in chapter_pages]
character_bank["images"] = [read_image(x) for x in character_bank["images"]]

with torch.no_grad():
    per_page_results = model.do_chapter_wide_prediction(chapter_pages, character_bank, use_tqdm=True, do_ocr=True)

transcript = []
for i, (image, page_result) in enumerate(zip(chapter_pages, per_page_results)):
    model.visualise_single_image_prediction(image, page_result, f"page_{i}.png")
    speaker_name = {
        text_idx: page_result["character_names"][char_idx] for text_idx, char_idx in page_result["text_character_associations"]
    }
    for j in range(len(page_result["ocr"])):
