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？
