我试图在Jupyter笔记本中创建一个Sankey图表,我的代码基于
the first example shown here.
我最终得到了这个,我可以运行而不会出现任何错误:
import numpy as npy
import pandas as pd
import plotly as ply
ply.offline.init_notebook_mode(connected=True)
df = pd.read_csv('C:\\Users\\a245401\\Desktop\\Test.csv',sep=';')
print(df.head())
print(ply.__version__)
data_trace = dict(
type='sankey',domain = dict(
x = [0,1],y = [0,1]
),orientation = "h",valueformat = ".0f",node = dict(
pad = 10,thickness = 30,line = dict(
color = "black",width = 0.5
),label = df['Node,Label'].dropna(axis=0,how='any'),color = df['Color']
),link = dict(
source = df['Source'].dropna(axis=0,target = df['Target'].dropna(axis=0,value = df['Value'].dropna(axis=0,)
)
print(data_trace)
layout = dict(
title = "Test",height = 772,width = 950,font = dict(
size = 10
),)
print(layout)
fig = dict(data=[data_trace],layout=layout)
ply.offline.iplot(fig,filename='Test')
csv文件看起来像这样:
Source;Target;Value;Color;Node,Label 0;2;2958.5;#262C46;Test 1 0;2;236.7;#262C46;Test 2 0;2;1033.4;#262C46;Test 3 0;2;58.8;#262C46;Test 4 0;2;5.2;#262C46;Test 5 0;2;9.4;#262C46;Test 6 0;2;3.4;#262C46;Test 7
它似乎运行良好,各种输出乍一看,但ply.offline.iplot的最终输出(图,文件名=’测试’)只显示一个大的空白字段:
在运行笔记本中的所有单元格后,终端看起来像这样:
有人可以指点我到哪里错了吗?

解决方法
在过去的Jupyter中,我遇到了类似的问题 – 有时候出现错误的时候/为什么情节会出现意外不一致.从增加的数据速率限制开始可能值得一试.
jupyter notebook –NotebookApp.iopub_data_rate_limit = 1.0e10
