plotly plots in jupyter notebooks: Validation fails when saving

问题

I'am new to plotly and I'am having a problem with my plots when generating them inside jupyter notebooks.

Whenever I generate a plot, evrything works fine, but when I try to save the notebook I get an error message telling me that the notebook validation failed because it's not valid under any of the given schemas (example taken straight from the plot.ly webiste).

Here is an example:

import plotly.plotly as py
iplot([{"x": [1, 2, 3], "y": [3, 1, 6]}])

I get the following message when I try to save the notebook: Notebook Validation failed: {u'data': [{u'y': [3, 1, 6], u'x': [1, 2, 3]}], u'layout': {}} is not valid under any of the given schemas:

{
 "data": [
  {
   "y": [
    3, 
    1, 
    6
   ], 
   "x": [
    1, 
    2, 
    3
   ]
  }
 ], 
 "layout": {}
}

Thank you!

The ploty team fixed the issue, here is the ticket

Upgrading nbformat, with either

pip install --upgrade nbformat

or

conda update nbformat

fixes it.
