Salesforce/blip2-opt-2.7b · Inference API usage

I am trying to use the inference API and I can't seem to add the 'question' in the inputs for the API, would anyone know how to do it?

This is my current script. It does return a caption, but it does not seem to take into account the text input.

import base64
import json

import requests

API_URL = "https://api-inference.huggingface.co/models/Salesforce/blip2-opt-2.7b"

headers = {"Authorization": f"Bearer {'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'}"}
json_request = {
    "inputs": "How could someone get out of the house?",
    "parameters":
        {

            "max_new_tokens": 100
        },
    "options":
        {"wait_for_model": True}
}


def query(filename):
    with open(filename, "rb") as f:
        data = f.read()
    json_request['image'] = base64.b64encode(data).decode('utf-8')
    response = requests.request("POST", API_URL, headers=headers, json=json_request)
    return json.loads(response.content.decode("utf-8"))


data = query("house.jpg")
print(data)
