Local offline mode does not work in Jupyter Notebook 5

Hi!

After upgrading jupyter notebook to v5 - when using plotly with init_notebook_mode(connected=False) (which is the default flag), with each call to iplot an exception is raised

Uncaught Error: Script error for "plotly"
http://requirejs.org/docs/errors.html#scripterror
    at makeError (require.js:165)
    at HTMLScriptElement.onScriptError (require.js:1732)

The canvas is still drawn but it’s white. when reverting to notebook v4.3.2, plotly works again.

Note that if using connected=True (which will fetch plotly.js from the CDN) it will work.

Thanks!

@averri I ran your code with the same library versions and I got an empty plot too. It displays the plot in jupyter notebook 5.0.1 only if you import download_plotlyjs:

from plotly.offline import download_plotlyjs, init_notebook_mode, iplot
init_notebook_mode()
import plotly.graph_objs as go
import numpy as np
x=np.linspace(0, 1, 100)
y=np.sin(2*np.pi*x)
fig=go.Figure(data=[go.Scatter(x=x, 
                               y=y)]
                      )
iplot(fig)

I have been using plotly in offline mode from within Jupyter notebook. I have been getting the plots. But suddenly today I see that I am either getting a blank output (no error but no plot as well) for the following code:

---

import plotly.offline as pltly import plotly.graph_objs as go import numpy as np

N = 500 random_x = np.linspace(0, 1, N) random_y = np.random.randn(N)

Create a trace

trace = go.Scatter( x = random_x, y = random_y ) data = [trace] pltly.iplot(data, filename=‘basic-line’)

---

Or showing this error: “Aw, snap! We didn’t get a username with your request. Don’t have an account? https://plot.ly/api_signup Questions? [e-mail]” for similar codes like the following:

---

#Linechart cf.datagen.lines().iplot(kind=‘scatter’,xTitle=‘Dates’,yTitle=‘Returns’,title=‘Cufflinks - Line Chart’)

---

      or

---

import plotly.offline as pltly import cufflinks as cf import pandas as pd import numpy as np df = pd.DataFrame(np.random.rand(10, 4), columns=[‘a’, ‘b’, ‘c’, ‘d’]) df.iplot(kind=‘area’, fill=True, filename=‘cufflinks/stacked-area’)

jupyter notebook version= 5.7.4 plotly = 3.7.0
