I am going to provide a gradio app from huggingface that allows you to choose a lora for the flux.1 model and run image generation with it. Make a new app that is not for choosing a lora, but just running image generation with a hardcoded lora. for each prompt, the app should generate an image with and without the lora and display them both. Here is the app:import gradio as gr
import json
import logging
import torch
from PIL import Image

from diffusers import DiffusionPipeline
import copy

import time

# Load LoRAs from JSON file
with open('loras.json', 'r') as f:
    loras = json.load(f)

# Initialize the base model
base_model = "black-forest-labs/FLUX.1-dev"
pipe = DiffusionPipeline.from_pretrained(base_model, torch_dtype=torch.bfloat16)

MAX_SEED = 2**32-1

    def __init__(self, activity_name=""):
        self.activity_name = activity_name

    def __enter__(self):
        self.start_time = time.time()
        return self
    
    def __exit__(self, exc_type, exc_value, traceback):
        self.end_time = time.time()
        self.elapsed_time = self.end_time - self.start_time
        if self.activity_name:
            print(f"Elapsed time for {self.activity_name}: {self.elapsed_time:.6f} seconds")
        else:
            print(f"Elapsed time: {self.elapsed_time:.6f} seconds")
