KeyError：'plotly_domain‘

Question

我正在运行来自这里的代码

import plotly
import plotly.plotly as py
from plotly.tools import FigureFactory as FF

import numpy as np
import pandas as pd
print(plotly.__version__)
dataframe = pd.DataFrame(np.random.randn(100, 3),
                         columns=['Column A', 'Column B', 'Column C'])

fig = FF.create_scatterplotmatrix(dataframe, diag='histogram', index='Column A',
                                  colormap=['rgb(100, 150, 255)', '#F0963C', 'rgb(51, 255, 153)'],
                                  colormap_type='seq', height=800, width=800)
py.iplot(fig, filename = 'Custom Sequential Colormap')

我得到了一个错误：

/Library/Frameworks/Python.framework/Versions/3.4/bin/python3.4 /Users/mona/PycharmProjects/PythonCodes/plotly_viz.py

This is the format of your plot grid:
[ (1,1) x1,y1 ]  [ (1,2) x2,y2 ]
[ (2,1) x3,y3 ]  [ (2,2) x4,y4 ]

Traceback (most recent call last):

你知道问题是什么吗?怎么解决？我是在巧妙地尝试，但我的第一次尝试碰巧是失败的！

Answer 1

基于这个答案，尝试使用py.plot而不是py.iplot。

在python中巧妙地使用域‘绘制散点图时

原因是iplot是用于ipython会话的。
