Plots from Colab don’t show in Nbviewer

[mklilley]

I posted this on the plotly community forum but so far got no traction so I'm reporting this here.

• What I did:
  • Created this Colab notebook with a simple plotly line chart
  • Added pio.renderers.default = "notebook_connected+colab" as per Plotly’s instructions for using Multiple Renderers
  • Pushed it to this public Github repo
  • Loaded the notebook in Nbviewer
• What I expected:
  • When loading in Nbviewer, I expected to see the rendered plotly graph as I did in Colab
• What I saw:
  • No rendered plot in Nbviewer
  • Plotly-colab-nbviewer.ipynb:14916 Uncaught ReferenceError: Plotly is not defined at Plotly-colab-nbviewer.ipynb:14916:462 in the Brave dev tools
• What seems strange:
  • When I look at the HTML inside Nbviewer, I do see a script tag that should pull in Plotly and it’s right next to the script that makes the plot.

    <script charset="utf-8" src="https://cdn.plot.ly/plotly-2.35.2.min.js"></script>
   <div id="5a0806d5-3da7-4c16-af56-b5fd7c6a67cb" class="plotly-graph-div" style="height:525px; width:100%;"></div>
  <script type="text/javascript">                                    
    window.PLOTLYENV=window.PLOTLYENV || {};  if (document.getElementById("5a0806d5-3da7-4c16-af56-b5fd7c6a67cb")) {  Plotly.newPlot("5a0806d5-3da7-4c16-af56-b5fd7c6a67cb",  [{"mode":"lines","name":"Simple Line","x":["2023-01-01T00:00:00","2023-01-02T00:00:00","2023-01-03T00:00:00","2023-01-04T00:00:00","2023-01-05T00:00:00","2023-01-06T00:00:00","2023-01-07T00:00:00","2023-01-08T00:00:00","2023-01-09T00:00:00","2023-01-10T00:00:00"],"y":[1,2,3,4,5,6,5,4,3,2],"type":"scatter"}], ...

I’ve seen a few posts that seem somewhat similar, but I thought I’d add some more details to the bug.

Any thoughts?

Hello there 👋. I appreciate there are probably lots of bugs that have higher priority than this one, but I just wanted to see if anyone had any thoughts on this? Did anyone else manage to reproduce it?

Even though it is not made in Colab, neither my simple notebook doesn't get rendered where plotly shows up.

From comments on this PR #5504 this issue seems to be fixed by first installing the latest plotly 6.8 via

%pip install -q --upgrade --force-reinstall "plotly==6.8.0"

See the demo here https://nbviewer.org/github/mklilley/test/blob/main/Plotly-colab-nbviewer.ipynb
