使用 IPython 未显示绘图图
我正在尝试通过将 官方示例 粘贴到 IPython< 中来尝试情节表达/代码> 控制台。
requirements.txt
ipython
plotly
pandas
运行以下内容
import plotly.express as px
if __name__ == "__main__":
import IPython; IPython.embed(using=False)
粘贴此内容：
In [1]: df = px.data.gapminder().query("country=='Canada'")
...: fig = px.line(df, x="year", y="lifeExp", title='Life expectancy in Canada')
...: fig.show()
...:
In [2]:
什么也没有发生。如果我只是将整个过程作为脚本运行而不使用 IPython，它就可以正常工作（打开一个浏览器页面）。然而在开发过程中我宁愿能够玩玩。
有什么想法为什么这不起作用吗？

I'm trying out plotly express by pasting the official example in an IPython console.
requirements.txt
ipython
plotly
pandas
Run the below
import plotly.express as px
if __name__ == "__main__":
import IPython; IPython.embed(using=False)
Paste this:
In [1]: df = px.data.gapminder().query("country=='Canada'")
...: fig = px.line(df, x="year", y="lifeExp", title='Life expectancy in Canada')
...: fig.show()
...:
In [2]:
Nothing happens. It works fine (a browser page opens up) if I just run the whole thing as a script without IPython. However during development I would rather be able to play around.
Any ideas why this isn't working?

我遇到了类似的问题，如果我使用 conda 从名为 my_env 的虚拟环境启动 Jupyter Notebook：
conda activate my_env，然后是jupyter notebook，然后是fig.show()不会显示任何内容。在他们的故障排除页面之后，我发现fig.show('notebook')将使用 IPython 显示该图。我希望该链接能帮助您找到问题！Have you checked here?

I'm having a similar issue where if I launch Jupyter Notebook from a virtual environment called my_env with conda:
conda activate my_envand thenjupyter notebook, thenfig.show()won't show anything. Following their troubleshooting page, I found thatfig.show('notebook')will show the figure using IPython. I hope that link will help you find the problem!
