# 值错误：适配器配置与基础模型不匹配。期望适配器类型为'lora'，但得到'ia3'

- **ID:** `huggingface/peft-adapter-config-mismatch`
- **领域:** huggingface
- **类别:** config_error
- **验证级别:** ai_generated
- **修复率:** 88%

## 根因

将一个使用某种方法（例如LoRA）保存的PEFT适配器加载到期望不同方法（例如IA3）的模型上，导致配置不匹配。

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |
|------|------|------|------|
| peft>=0.5.0 | active | — | — |
| transformers>=4.30.0 | active | — | — |

## 解决方案

1. ```
   Load the adapter with the correct PEFT method class explicitly.
   ```
2. ```
   Inspect adapter_config.json and set peft_type manually before loading.
   ```
3. ```
   Re-create the adapter using the correct method from scratch.
   ```
