Inference

from transformers import AutoProcessor, PaliGemmaForConditionalGeneration
from PIL import Image
import torch
import json

# Load model and processor
model_id = "google/paligemma-3b-pt-448"
peft_adapter_id = "riphunter7001x/PaliGemma3_FT_OCR"

model = PaliGemmaForConditionalGeneration.from_pretrained(model_id, device_map="auto")
processor = AutoProcessor.from_pretrained(model_id)
model.load_adapter(peft_adapter_id).eval()

TORCH_DTYPE = model.dtype
DEVICE = torch.device("cuda" if torch.cuda.is_available() else "cpu")

# Load and process image
image = Image.open("image.jpg")

prefix = "<image>extract Document data in JSON format"

inputs = processor(
    text=prefix,
    images=image,
    return_tensors="pt"
).to(TORCH_DTYPE).to(DEVICE)

prefix_length = inputs["input_ids"].shape[-1]

with torch.inference_mode():
    generation = model.generate(**inputs, max_new_tokens=512, do_sample=False)
    generation = generation[0][prefix_length:]
    decoded = processor.decode(generation, skip_special_tokens=True)
    print(json.dumps(json.loads(decoded), indent=4))

This code loads the fine-tuned PaliGemma model, processes an input image, and extracts document data in JSON format.
