-# SDXL-controlnet: Zoe-Depth
-
-These are ControlNet weights trained on stabilityai/stable-diffusion-xl-base-1.0 with zoe depth conditioning. [Zoe-depth](https://github.com/isl-org/ZoeDepth) is an open-source SOTA depth estimation model which produces high-quality depth maps, which are better suited for conditioning.
-
-You can find some example images in the following.

-## Usage
-
-Make sure first to install the libraries:
-
-```bash
-pip install accelerate transformers safetensors diffusers
-```
-
-And then setup the zoe-depth model
-
-```
-import torch
-import matplotlib
-import matplotlib.cm
-import numpy as np

-
-### Training
-
-Our training script was built on top of the official training script that we provide [here](https://github.com/huggingface/diffusers/blob/main/examples/controlnet/README_sdxl.md). 
-
-#### Training data and Compute
-The model is trained on 3M image-text pairs from LAION-Aesthetics V2. The model is trained for 700 GPU hours on 80GB A100 GPUs.
-
-#### Batch size
-Data parallel with a single gpu batch size of 8 for a total batch size of 256.
-
-#### Hyper Parameters
-Constant learning rate of 1e-5.
-
-#### Mixed precision
