Are you using the examples from the "master" branch on GitHub? If so, the master branch always has the very latest. If you are running an older release then that means the master branch examples might have code or features that are too new for you. If you are running an older release, you should check out the branch specific to your release, e.g

  https://github.com/bokeh/bokeh/tree/0.12.2/examples

Thanks,

Bryan

Hi,

I just noticed it looks like you ran "bokeh serve surface3d/main.py", is that correct? To run "directory style" apps, you need to start by passing the *directory* to bokeh server, i.e.

  bokeh serve surface3d

Apart from that, I am not sure. I just tested the app in both python 2 and python 3 environments with bokeh 0.12.2 installed, and they functioned as expected.

Hi Bryan,
Thanks for feedback. Initially I downloaded the example set from the master branch but now I downloaded 0.12.2 example set still not able to run surface3d example. Getting the same error.

Bryan I did not know to run directories examples in this way.

But for other examples like movies I could not face any issue. I could view the application using bokeh serve --show main.py.

By following the suggested way for execution I was able to execute.

Thanks
