JSON fails but regex does not #1232

Open cpfiffer opened 3 days ago

cpfiffer commented 3 days ago

Describe the issue as clearly as possible:

When using outlines with the Llama 3.2 Vision model, simple regex pattern generation works, but JSON schema-based generation fails with index out of bounds errors.

Steps/code to reproduce the bug:

from io import BytesIO
import json
from urllib.request import urlopen
from PIL import Image
from pydantic import BaseModel
import outlines
from transformers import MllamaForConditionalGeneration, AutoProcessor
from transformers import AutoTokenizer
from outlines.fsm.json_schema import build_regex_from_schema

def img_from_url(url):
    img_byte_stream = BytesIO(urlopen(url).read())
    return Image.open(img_byte_stream).convert("RGB")

image_url="https://upload.wikimedia.org/wikipedia/commons/9/98/Aldrin_Apollo_11_original.jpg"
image= img_from_url(image_url)

model_id = "meta-llama/Llama-3.2-11B-Vision-Instruct"
tokenizer = AutoTokenizer.from_pretrained(model_id) 
model = MllamaForConditionalGeneration.from_pretrained(
    model_id,
    device_map="auto",
)
processor = AutoProcessor.from_pretrained(model_id)

llm = outlines.models.TransformersVision(model, tokenizer,processor)

# Works
pattern = "Mercury|Venus|Earth|Mars|Saturn|Jupiter|Neptune|Uranus|Pluto"
planet_generator = outlines.generate.regex(llm, pattern)
out = planet_generator(
    "What: <|image|>",
    [image]
)
print(out)
# Fails
class ImageData(BaseModel):
    caption: str

im_reg = build_regex_from_schema(json.dumps(ImageData.model_json_schema()))
print(im_reg)
generator = outlines.generate.regex(llm, im_reg)

out = generator(
    "What: <|image|>",
    [image]
)
print(out)

Expected result:

Mercury, Venus, Earth, etc.
