Trainable Parameters: 0.000M正常吗

**Summary[问题简述（一句话）]**
我在训练自己的synthesizer时遇到如下提示：

\Saving the json with %s
data\ckpt\synthesizer\dan\dan.json
Trainable Parameters: 0.000M

是否正常？这是在训练吗？

**Env & To Reproduce[复现与环境]**
Python 3.9.8
模型用的是“75k steps 用3个开源数据集混合训练”

**Screenshots[截图（如有）]**

No source file, test, or training entry point is named in the issue. Reproduce the run with the stated Python version and 75k-step mixed-data setup, then trace the parameter-count output and training logs to determine whether training is actually progressing; done means documenting whether 0.000M is expected and identifying the cause if it is not.
