Root Cause

PEFT (Parameter-Efficient Fine-Tuning) prevents loading multiple adapters with the same name to avoid weight conflicts. This occurs when calling `load_adapter` twice with the same name or when an adapter named 'default' is already active.

generic

中文

PEFT（参数高效微调）阻止加载同名适配器以避免权重冲突。当使用相同名称两次调用 `load_adapter` 或名为 'default' 的适配器已激活时，会发生此错误。

Workarounds

  1. 95% success Use a unique name for each adapter load, such as including a timestamp or identifier. For example: `model.load_adapter(peft_model_id, adapter_name='my_adapter_v2')`. 
    Use a unique name for each adapter load, such as including a timestamp or identifier. For example: `model.load_adapter(peft_model_id, adapter_name='my_adapter_v2')`.
  2. 85% success Disable the current adapter before loading a new one with the same name using `model.disable_adapter()`. 
    Disable the current adapter before loading a new one with the same name using `model.disable_adapter()`.

中文步骤

  1. Use a unique name for each adapter load, such as including a timestamp or identifier. For example: `model.load_adapter(peft_model_id, adapter_name='my_adapter_v2')`.
  2. Disable the current adapter before loading a new one with the same name using `model.disable_adapter()`.

Dead Ends

Common approaches that don't work:

  1. 30% fail

    Removing the adapter with `delete_adapter('default')` before loading a new one may cause errors if the adapter is currently active and the model has been trained with it.

  2. 50% fail

    Setting `adapter_name=None` in `load_adapter` does not auto-generate a unique name; it defaults to 'default' again.
