    != session.get_session_config()['plotly_domain']):
KeyError: 'plotly_domain'

Process finished with exit code 1

2、错误原因

import plotly;
import plotly.plotly as py;
import plotly.graph_objs as go;

plotly.tools.set_credentials_file(username='xxx',api_key='787889Pa0GMIkz1R3Z1BHy');

C = go.Bar(
    x = [1,2,3,4,5,6,7,8],
    y = [7889,5623,9856,1254,4878,5656,3562,7445]
)

data = [C];

py.iplot(data,filename='柱状图');

3、解决办法

      在进行绘制图形时，需要调用plot()方法，而不是iplot()方法

import plotly;
import plotly.plotly as py;
import plotly.graph_objs as go;

plotly.tools.set_credentials_file(username='xxx',api_key='56895656GMIkz1R3Z1BHy');

C = go.Bar(
    x = [1,2,3,4,5,6,7,8],
    y = [7889,5623,9856,1254,4878,5656,3562,7445]
)

data = [C];

py.plot(data,filename='柱状图');
