Inference

import torch
from diffusers import DiffusionPipeline

model_id = '/workspace/models/FLUX.1-dev'
adapter_id = 'hg-ai-team/autotrain-08-01'
pipeline = DiffusionPipeline.from_pretrained(model_id, torch_dtype=torch.bfloat16) # loading directly in bf16
pipeline.load_lora_weights(adapter_id)

prompt = "A photo-realistic image of a cat"


## Optional: quantise the model to save on vram.
## Note: The model was quantised during training, and so it is recommended to do the same during inference time.
