解决方案

  1. List available adapters and load the correct one: `model.load_adapter('lora_v1')` or `PeftModel.from_pretrained(model, 'path/to/checkpoint', adapter_name='lora_v1')`
  2. If loading a single adapter, use `PeftModel.from_pretrained(model, 'path/to/checkpoint')` without specifying adapter_name, which defaults to 'default'.

无效尝试

常见但无效的做法:

  1. Rename the adapter folder to 'my_adapter' manually 80% 失败

    PEFT uses internal metadata to track adapter names; renaming the folder without updating the metadata file (adapter_config.json) causes a mismatch.

  2. Set `load_in_8bit=True` to bypass adapter loading 90% 失败

    Loading in 8-bit doesn't skip adapter loading; it still tries to find the adapter and fails with the same error.
