TypeError: argument of type 'bool' is not iterable ERROR: Exception in ASGI application

在调试运行python应用TRELLIS的时候发生报错，无法启动应用，部分错误信息如下：

ERROR: Exception in ASGI application

这个问题是gradio和pydantic版本冲突导致的，我当前gradio版本为4.44.1，pydantic版本为2.11.3

解决办法降低pydantic版本就可以了，重新安装pydantic版本2.10.6

pip install --force-reinstall pydantic==2.10.6
