* fix: load_in_*bit not properly read * fix: load_*bit check * fix: typo * refactor: load * bit handling * feat: add test dpo lora multi-gpu * fix: turn off sample packing for dpo * fix: missing warmup_steps * fix: test to load in 8bit for lora * skip 8bit lora on h100, add 4bit lora on h100 to multi gpu tests * chore: reduce max_steps --------- Co-authored-by: Wing Lian <wing.lian@gmail.com>
