我不明白为什么这段代码不起作用。数据是虚构的,我只希望能够使用plotly进行时间序列可视化。
该模块曾经在Kaggle内核中对我有用:
https://www.kaggle.com/aubertsigouin/organizing-macrohistorical-datasets/data
奇怪的是,我无法使其再次运行。它说:«AttributeError:模块'plotly'没有属性'plotly'»。
任何提示吗?

答案 0 :(得分:3)
尝试import plotly.plotly
。
我建议给它一个别名,例如import plotly.plotly as plt
。
本质上,在plotly.plotly
中,第一个正在调用plotly
程序包,第二个在.
之后正在从程序包中调用函数。
编辑:不管是否对您有用,请告诉我。

首先我建议安装chart_studio(如果您在conda promt中使用anaconda安装)
pip install chart-studio
然后使用以下方法在jupyter笔记本中导入:
import chart_studio.plotly as py
答案 2 :(得分:0)
import plotly.express as px
这是最新更新。
