根因分析

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。

English

Loading a PEFT adapter saved with one method (e.g., LoRA) onto a model that expects a different method (e.g., IA3), causing a configuration mismatch.

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.

无效尝试

常见但无效的做法:

  1. 95% 失败

    This flag only handles size mismatches, not adapter type mismatches.

  2. 98% 失败

    The issue is not library installation but adapter metadata stored in the adapter_config.json file.
