Model Descriptions:

This repo contains OpenVino model files for [SimianLuo's LCM_Dreamshaper_v7](https://huggingface.co/SimianLuo/LCM_Dreamshaper_v7).

Hugging Face Demo on CPU:

Generation Results:

By converting model to OpenVino format and using Intel(R) Xeon(R) Gold 5220R CPU @ 2.20GHz 24C/48T x 2 we can achieve following results compared to original PyTorch LCM.

Results time includes first compile and reshape phases and should be taken with grain of salt because benchmark was run using 2 socketed server which can underperform in those types of workload. 

Number of images per batch is set to 1

To run the model yourself, you can leverage the 🧨 Diffusers/🤗 Optimum library:
1. Install the library:
```
pip install diffusers transformers accelerate optimum 
pip install --upgrade-strategy eager optimum[openvino]
```

2. Clone inference code:
```
git clone https://huggingface.co/deinferno/LCM_Dreamshaper_v7-openvino
cd LCM_Dreamshaper_v7-openvino
```

2. Run the model:
```py
from lcm_ov_pipeline import OVLatentConsistencyModelPipeline
from lcm_scheduler import LCMScheduler

model_id = "deinferno/LCM_Dreamshaper_v7-openvino"

scheduler = LCMScheduler.from_pretrained(model_id, subfolder = "scheduler")

# Use "compile = True" if you don't plan to reshape and recompile model after loading
# Don't forget to disable OpenVino cache via "ov_config = {"CACHE_DIR":""}" because optimum won't use it anyway and it will stay as dead weight in your RAM when loading pipeline again
pipe = OVLatentConsistencyModelPipeline.from_pretrained(model_id, scheduler = scheduler, compile = False, ov_config = {"CACHE_DIR":""})

prompt = "Self-portrait oil painting, a beautiful cyborg with golden hair, 8k"

# Can be set to 1~50 steps. LCM support fast inference even <= 4 steps. Recommend: 1~8 steps.

width = 512
height = 512
num_images = 1
batch_size = 1
num_inference_steps = 4

# Reshape and recompile for inference speed

pipe.reshape(batch_size=batch_size, height=height, width=width, num_images_per_prompt=num_images)
pipe.compile()

images = pipe(prompt=prompt, width=width, height=height, num_inference_steps=num_inference_steps, guidance_scale=8.0, output_type="pil").images
```
