Gridplot bug

Community Support

DougRMay 18, 2017   #1

Hi,

I have recently started using Bokeh and it is a very impressive tool.

I think I have found a bug in Bokeh whilst experimenting with the gridplot command, From Jupyter, I get the following error message:

Javascript error adding output!

Error: duplicate edit variable: _height 7a9ef649-8625-410c-bcbc-2cdf6f9b89ae

See your browser Javascript console for more details.

I have attached a sample Jupyter Notebook which demonstrates this. All inline plotting fails after this first error message is first created unless I rerun the output_notebook() command. It appears that I cannot plot the same figure twice when using the ‘gridplot’ method.

Is anyone able to reproduce this error?

Cheers, DougR

Hi,

It's not the grid plot, you are running into this:

  Issue Validation error when plots are duplicated in one document · Issue #1650 · bokeh/bokeh · GitHub

because you are using the same plot twice in one document.

Thanks,

Bryan

Bryan,

Thanks for the quick response and link to the issue. Its good to know that the problem I had is already being tracked. I failed to spot it when I googled it.

Well, just to be clear, the resolution to that issue may end up being "wont fix" or "invalid". It's not clear at all to me what a real, actual use-case for including the exact same plot twice in one document could be. In which case it's hard to justify effort to "fix" a non-problem. However, if you have a justification for why it would ever be reasonable to include the same plot object twice in a real situation, please comment in the issue.

I’m not sure that there is a need to have the same figure in a document. The issue I had was the persistent error messages, even when running valid commands, after I made the mistake of putting 1 figure in a gridplot twice. Restarting the Jupyter kernel or running the “output_notebook()” command fixed the issue. Please see attached Jupyter Notebook which better describes this scenario.

Understood. The Notebook+Bokeh is a giant pile of interlocking state spread across two runtimes. There are situations that just cannot be gracefully recovered from without restarting. Perhaps the best resolution for that issue would be a giant red validation warning if a model is duplicated in a document (that's simple to do).

Thanks,

Bryan
