问题描述

我整天搜索如何在 google colaboratory jupyter notebooks 中显示绘图的输出.google colaboratory 有一个 stackoverflow 问题和官方教程，但它们都对我不起作用.

问题

如何在 google colaboratory 中显示 plotly 输出?

有可能吗?如果是这样，哪个版本的 plotly 或 cufflinks 适合您?

如果无法显示，能否将输出文件保存为.html在我们的google drive中手动打开查看?

感谢您的帮助.

解决方案

`plotly` 4.x版

从版本 4 开始，plotly 渲染器了解 Colab，因此以下内容足以在 Colab 和 Jupyter(以及 Kaggle、Azure、nteract 等其他笔记本)中显示图形:

导入 plotly.graph_objectsfig = go.Figure(go.Scatter(x=[1,2,3], y=[1,3,2]) )图.show()

`plotly` 3.x 版

我也在努力在 Google colab 中显示绘图图表，并偶然发现了这个线程，您在其中解释了网络上不同解决方案的问题.每个解决方案的感觉都是相同的.最后，当我看到这个视频时，我的搜索结束了.p>

我遵循了他的方法(可能与您已经尝试过的方法相似)，这对我有用.

按照建议通过 !pip install plotly --upgrade 和 restart runtime 在 colab 中升级 plotly.
评论升级选项，然后再重新运行您的笔记本
定义函数configure_plotly_browser_state()
调用 plotly 库
在您要调用 iplot 的每个单元格中调用如下所示的函数和笔记本模式
configure_plotly_browser_state()
init_notebook_mode(connected=False)
iplot(XXXXXX)

只需导入 plotly 库

如果这有帮助，请告诉我:)

I searched whole day how to display the outputs of plotly plots in google colaboratory jupyter notebooks. There is a stackoverflow question and also official tutorial from google colaboratory but both of them did not work for me.

Plotly notebook mode with google colaboratory
https://colab.research.google.com/drive/14oudHx5e5r7hm1QcbZ24FVHXgVPD0k8f#scrollTo=8RCjUVpi2_xd

The built-in google colaboratory plotly version is 1.12.12.

Test plotly version

import plotly
plotly.__version__
1.12.12

Load libraries

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns

Mount google drive

from google.colab import drive
drive.mount('/content/drive')

dat_dir = 'drive/My Drive/Colab Notebooks/data/'

Questions

How to display the plotly output in google colaboratory?

Is is possible ? If so which version of plotly or cufflinks is working for you?

If it is not possible to display, can we save the output file as .html in our google drive and open them manually and see them?

I appreciate your help.

解决方案

`plotly` version 4.x

As of version 4, plotly renderers know about Colab, so the following is sufficient to display a figure in both Colab and Jupyter (and other notebooks like Kaggle, Azure, nteract):

import plotly.graph_objects as go
fig = go.Figure( go.Scatter(x=[1,2,3], y=[1,3,2] ) )
fig.show()

`plotly` version 3.x

I was also struggling to display the plotly graphs in Google colab and stumbled upon this thread where you explained the problems with different solutions over the net. Feelings are the same for each one of the solutions. Finally, my search ended when I came across this video.

I followed his approach (might be similar to the ones you already tried) and this worked for me.

Upgrade plotly in colab thru !pip install plotly --upgrade and restart runtime as suggested.
Comment the upgrade option before re-running your notebook
Define the function configure_plotly_browser_state()
Invoke plotly libraries
Call function and notebook mode like below in every cell where you want to call iplot

configure_plotly_browser_state()

init_notebook_mode(connected=False)

iplot(XXXXXX)

Just import plotly libraries

Please let me know if this helps :)
