finetune results seems not very stable

use the default parameter,need I set a different LR?

使用默认参数，需要设置不同的 LR 吗？

Hello, has your issue been resolved? I'm not sure why the eval_loss keeps fluctuating around 0.69, and the eval_accuracy remains at 0.5.

Which datasets are you using? It is possible that the model fails to converge with some random seeds and hyperparameters. We observe same phenomenon on the COVID dataset before.

[zhujunru854]

My fine-tuning results with LoRa are similar to yours, but also very poor. I tried tweaking the lr and adding layers to lora, but the results didn't improve. I was using an extremely unbalanced CTCF binding site data and using the focal loss to calculate the loss
