the setting of tangent_warmup value

[renrenzsbbb]

thanks for your great. I find that you set tangent_warmup to 0 in WAN2PT1_14B_RES480P_T2V and 1000 in WAN2PT1_1PT3B_RES480P_T2V, can you introduce me the reason?

The warmup parameter is not very important. We find setting it to 1000 on 1.3B results in better motion and alignment with the teacher. For 14B, setting warmup to 0 seems more stable.

很感谢您的工作，我注意到您在 14B 场景下训练，对学生计算scm损失的下列代码会发生除零报错：dwarmup_ratio = min(1.0, iteration / self.config.tangent_warmup)

I have fixed the bug. Please try the newest version and appreciate any feedback!
