根因分析

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。

English

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.

解决方案

  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()`.

无效尝试

常见但无效的做法:

  1. 30% 失败

    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% 失败

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