Error using export_png

I have a figure() object that I wish to save as a png.

However, I get this error

raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: {“errorMessage”:“undefined is not an object (evaluating ‘window.Bokeh.documents’)”,“request”:{“headers”:{“Accept”:“application/json”,“Accept-Encoding”:“identity”,“Connection”:“close”,“Content-Length”:“393”,“Content-Type”:“application/json;charset=UTF-8”,“Host”:“127.0.0.1:54603”,“User-Agent”:“Python http auth”},“httpVersion”:“1.1”,“method”:“POST”,“post”:"{“script”: “\n // add private window prop to check that render is complete\n window._bokeh_render_complete = false;\n function done() {\n window._bokeh_render_complete = true;\n }\n\n var doc = window.Bokeh.documents[0];\n\n if (doc.is_idle)\n done();\n else\n doc.idle.connect(done);\n “, “args”: , “sessionId”: “4cf03ab0-aec2-11e7-aea9-3beff2afffb4”}”,“url”:”/execute",“urlParsed”:{“anchor”:"",“query”:"",“file”:“execute”,“directory”:"/",“path”:"/execute",“relative”:"/execute",“port”:"",“host”:"",“password”:"",“user”:"",“userInfo”:"",“authority”:"",“protocol”:"",“source”:"/execute",“queryKey”:{},“chunks”:[“execute”]},“urlOriginal”:"/session/4cf03ab0-aec2-11e7-aea9-3beff2afffb4/execute"}}

I’ve installed the dependencies.

Maybe I can also add another question. I’m trying to enable multiple brushed regions on a plot that is linked. So for example brush one area, then brush another area, maybe with a different highlight color. Is this possible?

Please make separate posts for separate questions.

Thanks,

Bryan

Hi,

In order to help, detailed version information for everything relevant will be needed,

Thanks,

I should mention I used conda-forge to install selenium. This gave me an error on selenium:

conda install selenium phantomjs pillow

Im on version 0.12.7 bokeh
and the package versions are I guess the latest

Hi,

I'm not trying to be unnecessarily short, but I'm not able to help with "I guess the latest". Detailed and complete version information for:

* OS
* browsers
* python
* selenium
* phantomjs
* pillow
* bokeh

are all needed in order to even start to speculate, or to try and reproduce the problem so it can be investigated.

Otherwise I can only suggest: have you tried not installing from conda-forge? I have no control over what's there and can make no guarantees that the versions there are suitable.

Thanks,

Bryan

OS: macOS Sierra 10.12.6
python: 3.6.2
selenium: 3.6.0
phantom: 2.1.1
pillow: 4.2.1
bokeh: 0.12.7

Apologies

So my version of selenium is in fact older:

❯ conda list selenium
# packages in environment at /Users/bryan/anaconda:

···

#
pytest-selenium 1.6.0 py_1 bokeh
selenium 3.4.3 py36_0 conda-forge

It's possible something about the newer selenium is currently incompatible. My first suggestion is to downgrade selenium to the version above and see if that works,

Thanks,

Bryan
