python - 使用 simple_plotly 时如何解决“NameError: name 'plotly_version' is not defined”？

问题描述

我正在尝试为我的硕士论文代码绘制地图。到目前为止，我只是在尝试https://nbviewer.jupyter.org/github/e2nIEE/pandapower/blob/develop/tutorials/plotly_maps.ipynb中的一个示例，所以我想一切都应该正常工作。但是，当尝试使用函数“simple_plotly”时，会出现 NameError。我怎样才能让它发挥作用？

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

解决方案

出现此错误是因为未安装 plotly，使用 pip 安装 ploty 即可。

Pip install plotly
