Write a detailed Python code using Stable Diffusion (via diffusers library) and a predictive ML model (e.g., TensorFlow for regression) to generate custom images for e-commerce, such as product mockups personalized to predicted user trends from sales data. The predictive part should process input data (e.g., CSV of customer demographics) to forecast popular styles/colors, then condition the image generation accordingly. Include steps for model setup, training on datasets like LAION, and API endpoints for automation. Tailor for freelancers building tools for businesses needing visual content creation, considering the 220% YoY demand surge.
