如何解决使用NameError时未定义“plotly_version”的“simple_plotly”问题？

Question

我正试图为我的硕士论文代码绘制一张地图。到目前为止，我只是在尝试一个来自maps.ipynb的例子，所以我认为一切都应该正常工作。但是，当尝试使用"simple_plotly“函数时，会出现一个NameError。我怎样才能使它发挥作用？

这是我得到错误的行：

from pandapower.plotting.plotly import simple_plotly
from pandapower.networks import mv_oberrhein
net = mv_oberrhein()
simple_plotly(net, on_map=True, projection='epsg:31467')

错误

NameError: name 'plotly_version' is not defined

发生此错误是因为没有巧妙地安装，请使用pip安装ploty，它将工作。

Pip install plotly
