# random

This is a standard PEFT LoRA derived from [flux/unknown-model](https://huggingface.co/flux/unknown-model).


The main validation prompt used during training was:
```
A Simple Pencil sketch of Marilyn Monroe, showcasing her iconic smile and glamorous hairstyle. The shading captures the softness of her features and the elegance of her famous pose, framed by a hint of her signature wardrobe.
```


## Validation settings
- CFG: `3.5`
- CFG Rescale: `0.0`
- Steps: `35`
- Sampler: `FlowMatchEulerDiscreteScheduler`
- Seed: `42`
- Resolution: `1024x1024`
- Skip-layer guidance: 

Note: The validation settings are not necessarily the same as the [training settings](#training-settings).

You can find some example images in the following gallery:

The text encoder **was not** trained.
You may reuse the base model text encoder for inference.

## Inference


```python
import torch
from diffusers import DiffusionPipeline

model_id = '/workspace/FLUX.1-dev'
adapter_id = 'mrtuandao/random'
pipeline = DiffusionPipeline.from_pretrained(model_id, torch_dtype=torch.bfloat16) # loading directly in bf16
pipeline.load_lora_weights(adapter_id)

prompt = "A Simple Pencil sketch of Marilyn Monroe, showcasing her iconic smile and glamorous hairstyle. The shading captures the softness of her features and the elegance of her famous pose, framed by a hint of her signature wardrobe."


## Optional: quantise the model to save on vram.
## Note: The model was not quantised during training, so it is not necessary to quantise it during inference time.
#from optimum.quanto import quantize, freeze, qint8
#quantize(pipeline.transformer, weights=qint8)
#freeze(pipeline.transformer)
    
pipeline.to('cuda' if torch.cuda.is_available() else 'mps' if torch.backends.mps.is_available() else 'cpu') # the pipeline is already in its target precision level
image = pipeline(
    prompt=prompt,
    num_inference_steps=35,
    generator=torch.Generator(device='cuda' if torch.cuda.is_available() else 'mps' if torch.backends.mps.is_available() else 'cpu').manual_seed(42),
    width=1024,
    height=1024,
    guidance_scale=3.5,
).images[0]
image.save("output.png", format="PNG")
