ent the newly learned concept. Custom Diffusion is unique because it can also learn multiple concepts at the same time. If you’re training on a GPU with limited vRAM, you should try enabling xFormers with --enable_xformers_memory_efficient_attention for faster training with lower vRAM requirements (16GB). To save even more memory, add --set_grads_to_none in the training argument to set the gradients to None instead of zero (this option can caus
