Describe the bug
This bug seems to effectively make the script unusable on v100 or lower with the latest update to the dreambooth_lora_sdxl script, I tried a lot with every compromise I could think of (even lowering resolution) but still can't get it to run without running out of memory, using full precision.
Reproduction
#!/usr/bin/env bash
!accelerate launch train_dreambooth_lora_sdxl.py
--pretrained_model_name_or_path="stabilityai/stable-diffusion-xl-base-1.0"
--pretrained_vae_model_name_or_path="madebyollin/sdxl-vae-fp16-fix"
--instance_data_dir="/content/in"
--output_dir="/content/out"
--variant="fp16"
--instance_prompt="Photo of a TOK person"
--resolution=1024
--train_batch_size=1
--adam_weight_decay=0.01
--mixed_precision="fp16"
--gradient_accumulation_steps=3
--gradient_checkpointing
--learning_rate=1e-4
--use_8bit_adam
--lr_scheduler="constant"
--lr_warmup_steps=0
--rank=16
--max_train_steps=625
--checkpointing_steps=250
--seed="0"
