But making the values to big will sometimes result in worse output. Play around to find good values. + +Gradient checkpointing reduces the memory requirements by ~50% but increases the runtime. +If you have enough RAM, you can make finetuning a bit faster by disabling checkpointing with `--no-checkpointing`. + +The default LORA rank can be specified with `--lora-r N`. +The LORA rank can be configured for each model tensor type separately with these command line options: + +```bash + --lora-r N LORA r: default rank.
