请问训练完毕，如何进行generation

我看repo并没有修改generate函数，是在评测时不需要task_type吗？这样会导致报错吧希望能有eval的代码

hi, I have modified the model.generate() function for loramoe, and it seems it is working. You can check the code here : https://github.com/mok0102/LoRAMoE.git -> Try run_test.sh Still the double check is needed for my modification. Please anyone check my modification and tell me if there is any error.

Ablustrund commented 6 months ago

@mok0102 @fzp0424 Thank you for your modified code. Because we provide the default value (i.e., None) for the task_type, it can be inferred without modifying. Additionally, we use opencompass to evaluate the fine-tuned models, and we've included profile details in the README.

同学，请问你能顺利generate了嘛，想请教一下~谢谢
