使用FigureWidget时plotly中的导入错误

Question

我尝试在Jupyter笔记本中运行以下命令：

import ipywidgets
import plotly.graph_objs as go
print(ipywidgets.__version__)

f = go.FigureWidget()
f

我得到以下错误

ImportError: Please install ipywidgets>=7.0.0 to use the FigureWidget class

我的ipywidgets版本是7.5.1。如何解决这个问题

Answer 1

我也有同样的问题。我首先通过查找python.exe的位置并在终端上运行python.exe -m pip install upgrade pip来升级我的pip

WARNING: You are using pip version 20.3.3; however, version 21.1.1 is available.
You should consider upgrading via the '~\Documents\python_projects\lost_sales_validation\venv_lost_sales\Scripts\python.exe -m pip install  upgrade pip' command.

一旦我有了最新版本的pip，我就运行了pip install ipywidgets upgrade
