Hey @patil-suraj, thanks for sharing this training code.

Could you please share with us the exact training args (without dataset sharing) you used to train inpainting model including number of GPUs used (to get total batch size)? Also the dataset size would help a lot.
Also would appreciate sharing wandb run if possible 🤗
