菜鸟初步接触，win10系统，因已装python，就选择了手动安装，按照教程操作步骤，在最后启动VeighNa Trader阶段，报错，代码如下：
D:\8-编程软件\vnpy-3.7.0\examples\veighnatrader>python run.py
Faile to import cython option pricing model, please rebuild with cython in cmd.
找不到数据服务驱动vnpy，使用默认的RQData数据服务

AttributeError: 'PySide6.QtWidgets.QDockWidget' object has no attribute 'DockWidgetFloatable'. Did you mean: 'DockWidgetFeature'?
同时，弹窗有个空白页面，提示触发异常(未响应)。网上找了好多教程都无法解决，也把库重新安装了，还是报错！
求助各位大神帮忙看看，该如何解决这个问题，万分感谢！！
