Bokeh: difficulty using High-level Chart in Jupyter Notebook

I was using Bokeh lib just fine until one day I switched to Anaconda distribution.

Just a simple spin of the bar chart example gave me a hard time: original code here, output_notebook part is what I added.

from bokeh.charts import Bar, output_file, show, output_notebook

# prepare some data
data = {"y": [6, 7, 2, 4, 5], "z": [1, 5, 12, 4, 2]}

# output to static HTML file
output_file("bar.html")

# create a new line chat with a title and axis labels
p = Bar(data, cat=['C1', 'C2', 'C3', 'D1', 'D2'], title="Bar example",
        xlabel='categories', ylabel='values', width=400, height=400)
output_notebook()
# show the results
show(p)

Error message as such:

ERROR:C:\Users\paul.dong\Documents\Apps\Anaconda\lib\site-packages\bokeh\validation\check.pyc:W-1003 (MALFORMED_CATEGORY_LABEL): Category labels are malformed: [field:caty] [first_value: C1:0.333333333333] [renderer: GlyphRenderer, ViewModel:GlyphRenderer, ref _id: e732fc67-f26f-48a1-ac50-dcf2ab0b0fd7]
ERROR:C:\Users\paul.dong\Documents\Apps\Anaconda\lib\site-packages\bokeh\validation\check.pyc:W-1003 (MALFORMED_CATEGORY_LABEL): Category labels are malformed: [field:catz] [first_value: C1:0.666666666667] [renderer: GlyphRenderer, ViewModel:GlyphRenderer, ref _id: 9737b7cd-c909-47eb-8c05-a8160b0ba23b]

So the html file output still normal, but the notebook output just won't show.

Appreciate your help.

Edit: I am using python 2.7 and bokeh 0.9.3 also jupyter v4

Just to post the temporary solution here.

It turns out the charting interface of Bokeh is going thru some big changes and obviously the validating steps are a good sign (hence the error messages).

But for now, if try to incorporate bokeh chart into your notebook, just downgrade to a version where you last made it work. For me it is bokeh 0.9.2.
