No module named objects [bokeh]

Question

I'm trying to run this script:

#Code will be significantly simplified in the 0.4 release
import time
from bokeh.objects import GlyphRenderer
renderer = [r for r in curplot().renderers if isinstance(r, GlyphRenderer)][0]
ds = renderer.data_source
while True:
    df = pd.io.json.read_json(url+json_call)
    ds.data["x"] = x+N*i
    ds.data["y"] = df.rssi
    ds._dirty = True
    session().store_obj(ds)
    time.sleep(1.5)
    i+=1

from: https://www.continuum.io/content/painless-streaming-plots-bokeh

but at this line:

from bokeh.objects import GlyphRenderer

I got:

No module named objects

The version I'm using is

0.11.1

On linux mint 17.1

did you try installing bokeh before trying the examples? If not, just run:

pip install bokeh

and try your script again.

if it does not work, it's likely that the bokeh sources changed, so you might want to change the

from bokeh.objects import GlyphRenderer

into

from bokeh.models.renderers import GlyphRenderer

cf the source code

---

At the first line of your example it states:

#Code will be significantly simplified in the 0.4 release

which means that the example's code was already about to be deprecated at the time of the writing of the tutorial.

So instead of copy/pasting that code, you should try to understand how it works, and recreate it using the documentation and sources:

• http://docs.bokeh.org/en/latest/docs/user_guide/quickstart.html#userguide-quickstart
• https://github.com/bokeh/bokeh

have fun!

Solution 2

The objects module was deleted in commit 5b5d28304c5ea209e243af5943917fe494d9ef9c (v0.7.1) after being deprecated in 8bb4a2f1f43b39b869c508ef7aee69f7aabb46b8 (v0.7.0). The deprecation message reads: "use bokeh.models instead". I leave finding GlyphRenderer in the current codebase as an exercise for you.

using "from bokeh.models.renderers import GlyphRenderer" but know I get: "name 'curplot' is not defined" seems that the code alone won't work

yup, I guess curplot() is defined else where, or is just for the sake of the example. I believe the documentation you're trying to copy from is just to show off principles and results, not really a base to build your own stuff upon.

Or if you look at the example's full source code, maybe it's part of the * it imports from bokeh.plotting. cf github.com/quasiben/bokeh_examples
