fix FT score

Fix OOM: prev LoRA on CPU + no_grad entire prev contribution (no saved tensors for backward)

Fix deprecation warnings: torch.load weights_only, cupy fromDlpack, as_target_tokenizer

fix: re-initialize trans_input/prompt_key after from_pretrained, add epsilon to norm, use_reentrant=False

fix: restore _set_gradient_checkpointing + enable_input_require_grads for gradient checkpointing

fix: use default use_reentrant=True for gradient checkpointing (model expects it)

fix: add FP16 safety check, dataset script check, LoRA sanity check

fix: LoRA reinit, gradient checkpointing use_reentrant=False, checkpoint existence check, collator padding alignment

add root_gainlora to repo for testing

reduce rubish

fix: trust_remote_code and abs paths for load_dataset

update

clean code

revert: discard all 2-GPU DataParallel/DDP changes, back to f51f791

DDP 2 GPU

fix: SVD jitter + trans_input.pt exists guard in both root and improve
