Resolves #2075
When saving PiSSA or OLoRA with the option to convert to normal LoRA, the LoRA weight shapes change, which means that some values like
r
andlora_alpha
need to be adjusted in the saved PEFT config. However, these modifications should be limited to the saved config, while the loaded config should stay the same.This PR implements this change by creating a copy of the config before modifying it.
