SDXL Finetuning Script Not Working
When using the script to run a full fine-tuning of Stable Diffusion XL in the examples folder, there is an error:Traceback (most recent call last):

TypeError: main() missing 1 required positional argument: 'args'It appears that this error is caused because Huggingface Accelerate is not passing the arguments into the training function. How do I fix this? Below is my config(I’m using a Google Colab with a TPU:compute_environment: LOCAL_MACHINE
debug: false
distributed_type: TPU
downcast_bf16: 'no'

sr5434:It turns out that the training script was the problem. I will create a PR to patch the issue shortly.
