How to fix PlotlyRequestError?

问题

I get an 'PlotlyRequestError: No message' when I execute the code.

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

Filedata = pd.read_csv('C:\\Documents\\Book4.csv')
data = [go.Scatter(x=Filedata.ix[:,0],y=Filedata.ix[:,1])]
layout = go.Layout(
title='Analysis 2016',
xaxis=dict(title='Startdate'),
yaxis=dict(title='Conductivity'))

fig = go.Figure(data=data, layout=layout)
py.iplot(fig)

回答1:

This is because you are trying to plot online which requires credentials based authentication. To plot offline, use plotly.offline's plot class to accomplish this without authentication.

from  plotly.offline import plot

and then use this plot to plot your figure.

I had the same issue and I don't know if you already found a solution, but importing plotly like this:

import plotly.plotly as py
import plotly.graph_objs as go
# these two lines allow your code to show up in a notebook
from plotly.offline import init_notebook_mode, iplot
init_notebook_mode()

And then calling iplot like this:

plotly.offline.iplot(...)

Solved my problem! Hope it helps :)
