 Sample image generation during training is not tested yet.
 
-Options are almost the same as LoRA training. The difference is `--blockwise_fused_optimizer`, `--double_blocks_to_swap` and `--cpu_offload_checkpointing`.  `--single_blocks_to_swap` is also available.

-`--blockwise_fused_optimizer` enables the fusing of the optimizer for each block. This is similar to `--fused_backward_pass`. Any optimizer can be used, but Adafactor is recommended for memory efficiency. `--fused_optimizer_groups` is deprecated due to the addition of this option for FLUX.1 training.

-`--double_blocks_to_swap` and `--single_blocks_to_swap` are the number of double blocks and single blocks to swap. The default is None (no swap). These options must be combined with `--blockwise_fused_optimizer`.

 `--cpu_offload_checkpointing` is to offload the gradient checkpointing to CPU. This reduces about 2GB of VRAM usage.
