Text-guided depth-to-image generation

The StableDiffusionDepth2ImgPipeline lets you pass a text prompt and an initial image to condition the generation of new images. In addition, you can also pass a `depth_map` to preserve the image structure. If no `depth_map` is provided, the pipeline automatically predicts the depth via an integrated depth-estimation model.

Start by creating an instance of the StableDiffusionDepth2ImgPipeline:

    import torch
    from diffusers import StableDiffusionDepth2ImgPipeline
    from diffusers.utils import load_image, make_image_grid

    pipeline = StableDiffusionDepth2ImgPipeline.from_pretrained(
        "stabilityai/stable-diffusion-2-depth",
        torch_dtype=torch.float16,
        use_safetensors=True,
    ).to("cuda")

Now pass your prompt to the pipeline. You can also pass a `negative_prompt` to prevent certain words from guiding how an image is generated:

    url = "http://images.cocodataset.org/val2017/000000039769.jpg"
    init_image = load_image(url)
    prompt = "two tigers"
    negative_prompt = "bad, deformed, ugly, bad anatomy"
    image = pipeline(prompt=prompt, image=init_image, negative_prompt=negative_prompt, strength=0.7).images[0]
    make_image_grid([init_image, image], rows=1, cols=2)
