+
+CosmicMan is a text-to-image foundation model specialized for generating high-fidelity human images. For more information, please refer to our research paper: [CosmicMan: A Text-to-Image Foundation Model for Humans](https://arxiv.org/abs/2404.01294). Our model is based on [runwayml/stable-diffusion-v1-5](https://huggingface.co/runwayml/stable-diffusion-v1-5). This repository provide UNet checkpoints for CosmicMan-SD. 
+
+
+## Requirements
+
+```python
+conda create -n cosmicman python=3.10
+source activate cosmicman
+pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118
+pip install accelerate diffusers datasets transformers botocore invisible-watermark bitsandbytes gradio==3.48.0
+```
+
+
+## Inference
+
+```python
+import torch
+from diffusers import StableDiffusionPipeline, UNet2DConditionModel, EulerDiscreteScheduler
+from huggingface_hub import hf_hub_download
+from safetensors.torch import load_file
+
+base_path = "runwayml/stable-diffusion-v1-5"
+unet_path = "cosmicman/CosmicMan-SD"
+
+# Load model.
+unet = UNet2DConditionModel.from_pretrained(unet_path, torch_dtype=torch.float16)
+pipe = StableDiffusionPipeline.from_pretrained(base_path, unet=unet, torch_dtype=torch.float16, variant="fp16").to("cuda")
+pipe.scheduler = EulerDiscreteScheduler.from_pretrained(base_path, subfolder="scheduler", torch_dtype=torch.float16)
+
+ 
+# Generate image.
+positive_prompt = "A closeup portrait shot against a white wall, a fit Caucasian adult female with wavy blonde hair falling above her chest wears a short sleeve silk floral dress and a floral silk normal short sleeve white blouse"
+negative_prompt = ""
+image = pipe(positive_prompt, num_inference_steps=30, 
+        guidance_scale=7.5, height=1024, 
+        width=1024, negative_prompt=negative_prompt, output_type="pil").images[0].save("output.png")
