Issue: [Bug] piqa or lambada dataset is not available
Root cause: Configuration Error

### Prerequisite

- [x] I have searched [Issues](https://github.com/open-compass/opencompass/issues/) and [Discussions](https://github.com/open-compass/opencompass/discussions) but cannot get the expected help.
- [x] The bug has not been fixed in the [latest version](https://github.com/open-compass/opencompass).

### Type

I'm evaluating with the officially supported tasks/models/datasets.

### Environment

I use python run.py --datasets piqa_gen --hf-type base --hf-path /root/autodl-tmp/deepseek-Qwen-1.5B --debug
but get error
other dataset like aime or math or HellaSwag or WinoGrande is avaliable, piqa and lambada dataset get error

### Reproduces the problem - code/configuration sample

python run.py --datasets piqa_gen --hf-type base --hf-path /root/autodl-tmp/deepseek-Qwen-1.5B --debug

### Reproduces the problem - command or script

python run.py --datasets piqa_gen --hf-type base --hf-path /root/autodl-tmp/deepseek-Qwen-1.5B --debug

### Reproduces the problem - error message
