Bokeh: ValueError: Out of range float values are not JSON compliant : <p>I came across this discussion (from a year ago): <a href="https://github.com/bokeh/bokeh/issues/2392" rel="noreferrer">https://github.com/bokeh/bokeh/issues/2392</a></p>

<p>I also saw the white screen without any errors..and then i tried to take a small subset of 2 columns and tried the below:</p>

<p>Since pandas just gets a bunch of rows with empty data in there as well, I tried dropna.. this resulted in there being no data at all. So instead I just specified the rows that should go into the df (hence the <code>df = df.head(n=19)</code> line)</p>

<pre><code>import pandas as pd
from bokeh.plotting import figure, output_file, show

df = pd.read_excel(path,sheetname,parse_cols="A:B")
df = df.head(n=19)
print(df)
rtngs = ['iAAA','iAA+','iAA','iAA-','iA+','iA','iA-','iBBB+','iBBB','iBBB-','iBB+','iBB','iBB-','iB+','iB','iB-','NR','iCCC+']
x= df['Score']
output_file("line.html")

p = figure(plot_width=400, plot_height=400, x_range=(0,100),y_range=rtngs)

# add a circle renderer with a size, color, and alpha
p.circle(df['Score'], df['Rating'], size=20, color="navy", alpha=0.5)

# show the results
#output_notebook()
show(p)
</code></pre>

<p>df:</p>

<pre><code>   Rating  Score
0    iAAA   64.0
1    iAA+   33.0
2     iAA    7.0
3    iAA-   28.0
4     iA+   36.0
5      iA   62.0
6     iA-   99.0
7   iBBB+   10.0
8    iBBB   93.0
9   iBBB-   91.0
10   iBB+   79.0
11    iBB   19.0
12   iBB-   95.0
13    iB+   26.0
14     iB    9.0
15    iB-   26.0
16     NR   49.0
17  iCCC+   51.0
18   iAAA   18.0
</code></pre>

<p>The above is showing me an output within the notebook, but still throws : <code>ValueError: Out of range float values are not JSON compliant</code></p>

<p>And also it doesn't (hence?) produce the output file as well. How do I get rid of this error for this small subset? Is it related to NaN values? Would that also solve the 'white screen of death' issue for the larger dataset?</p>

<p>Thanks vm for taking a look!</p>

<p>In case you would like to see the entire error:</p>
