`bokeh.sampledata.gapminder` not found

I wanted to run the gapminder example from this repo. I made a git clone of the current master branch changed the gapminder directory and started the bokeh server. It seems like the bokeh.sampledata.gapminder could not be found. See log. I only get a white browser window and error messages in the console. Do you have any idea what i could try?

I tried the current master branch: Commit 7093b5f8b5327dcc5f96c711e156fddba2d8b4e7

/home/max/.local/lib/python3.5/site-packages/bokeh/command/util.py:91: UserWarning: 
It looks like you might be running the main.py of a directory app directly.
If this is the case, to enable the features of directory style apps, you must
call "bokeh serve" on the directory instead. For example:

    bokeh serve my_app_dir/

If this is not the case, renaming main.py will supress this warning.

Simpler approach is to use bokeh sampledata console command, as described in bokeh’s quickstart.
