请问提示词长度小于负提示词长度会报错，为什么这样设计

感谢关注，我们对比过使用负提示词，和 learnable unconditions，结果显示使用 learnable unconditions 效果比负向提示词更稳定，也更好，因此在最终的推理中，我们并没有支持负向提示词。

Thank you for your attention. We have compared the use of negative prompts with learnable unconditions, and the results show that learnable unconditions deliver more stable and superior performance. Therefore, we did not support using negative prompts in the released code.
