TypeError: True is not JSON serializable

I’m creating a pandas dataframe in a bokeh-server dependent applet, and I’m getting an error that ‘TypeError: True is not JSON serializable’ referencing back to to L89 in protocol.py. This only happens when my df contains a column of bool values. I can convert the column to string, and back, but that seems rather inefficient. Is there a way I can get around this issue?

For more detail: I’m running bokeh 0.7.1 on python 2.7 via Anaconda, on Windows 7

This might be a bug, can you file a GitHub issue? We are about to have a code freeze for 0.8 release but this kind of fix could go in a dev build soon after that.

Thanks,

Bryan

I can reproduce this:

In [1]: import pandas as pd

In [2]: from bokeh.protocol import *

In [3]: pd.DataFrame({“x”: True, “y”: False}, index=[0, 1]).to_dict()
Out[3]: {‘x’: {0: True, 1: True}, ‘y’: {0: False, 1: False}}

In [4]: serialize_json(_)
(…)
TypeError: False is not JSON serializable

In [5]: type(3[‘x’][0])
Out[5]: numpy.bool

Bryan, I will take care of this.
