TypeError: object is not JSON serializable

Hi,

I am building several plots with DataColumnSources made from a pandas data frame with the following structure:

a.df.info()

<class ‘pandas.core.frame.DataFrame’>

DatetimeIndex: 2599 entries, 2005-02-16 to 2015-08-26

Data columns (total 8 columns):

col1 2599 non-null float64

col2 2599 non-null float64

col3 2599 non-null float64

col4 2599 non-null float64

col5 2599 non-null float64

col6 2599 non-null float64

col7 2599 non-null float64

col8 2599 non-null float64

the plots are collected in a dictionary and bokeh.embed.components is called (just like the embed_multiple.py example) then they are used in a render_template flask call (as a return of a route function).

I get the following error: “TypeError: <plotters.IHPlots object at 0x107b669b0> is not JSON serializable”

Is it the datetime64 or float64 that (still) create issues (I found a github issue about int64)?

Thanks

PS: the ultimate goal is not to call render_template but to pass them back to a JQuery request to avoid rendering the whole page.

Hi Alex,

I’m guessing that you’ve made your column data source using a data frame that includes a column of “plotters.IHPlots” objects - which aren’t serializable.

If this isn’t it, then you need to provide more information - a copy of your data and code.

Best,

Sarah Bird
