[Diffusion DPO] train script: 'Namespace' object has no attribute 'no_flip'

[kodinkod]

Describe the bug

I think there was a typo, because

no_flip not in args, only no_hflip

Reproduction

!accelerate launch train_diffusion_dpo_sdxl.py 
--pretrained_model_name_or_path="/home/ubuntu/mydrive/auto/stable-diffusion-webui/models/Stable-diffusion/ModelStep3" 
--pretrained_vae_model_name_or_path=madebyollin/sdxl-vae-fp16-fix 
--output_dir="Nebul-Redmond-SDXL" 
--mixed_precision="fp16" 
--dataset_name=kashif/pickascore 
--train_batch_size=8 
--gradient_accumulation_steps=1 
--gradient_checkpointing 
--use_8bit_adam 
--rank=8 
--learning_rate=8e-6 
--report_to="wandb" 
--lr_scheduler="constant" 
--lr_warmup_steps=0 
--max_train_steps=2000 
--checkpointing_steps=500 
--run_validation --validation_steps=50 
--seed="0" 
--report_to="wandb" 
--push_to_hub
