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, highlighted 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]

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

Appreciate your help.

I think the problem may have arisen due to the new validation functions in 0.9.3, which is a welcoming new feature to bokeh. But the growing pain here is some categorical index are now being interpreted correctly.

I have downgraded back to bokeh 0.9.2 and it is fine.
