| Some notes from the official [instruct-pix2pix](https://huggingface.co/spaces/timbrooks/instruct-pix2pix) Space by the authors | |
| and from the official [Diffusers docs](https://huggingface.co/docs/diffusers/main/en/api/pipelines/stable_diffusion/pix2pix) - | |
| If you're not getting what you want, there may be a few reasons: | |
| 1. Is the image not changing enough? Your guidance_scale may be too low. It should be >1. Higher guidance scale encourages to generate images | |
| that are closely linked to the text `prompt`, usually at the expense of lower image quality. This value dictates how similar the output should | |
| be to the input. This pipeline requires a value of at least `1`. It's possible your edit requires larger changes from the original image. | |
| 2. Alternatively, you can toggle image_guidance_scale. Image guidance scale is to push the generated image towards the inital image. Image guidance | |
| scale is enabled by setting `image_guidance_scale > 1`. Higher image guidance scale encourages to generate images that are closely | |
| linked to the source image `image`, usually at the expense of lower image quality. | |
| 3. I have observed that rephrasing the instruction sometimes improves results (e.g., "turn him into a dog" vs. "make him a dog" vs. "as a dog"). | |
| 4. Increasing the number of steps sometimes improves results. | |
| 5. Do faces look weird? The Stable Diffusion autoencoder has a hard time with faces that are small in the image. Try: | |
| * Cropping the image so the face takes up a larger portion of the frame. | |
