Thank you, I have successfully completed the training,output directory structure above.I have a question: How can I use the trained module? Can I use optimizer.bin instead of svd_xt.safetensors? The size of optimizer.bin is over 3GB, whereas svd_xt.safetensors is over 9GB. Therefore, I am wondering if they can be used interchangeably
