I tried your method with my API Key. But didn't work for me.

This link contains all my code containing source. Maybe you can edit my code and show me.

Thanks for the help

Which version of bokeh are you using, and what browser?

I have tested with bokeh versions 0.12.10 and 0.12.13, and it works on chrome.

I have 0.12.13. So, your code works, but when I try do it in my code (link - https://gist.github.com/nitinsaroha/a55e28688fb56915950760ef74b0ea27 ) it doesn't. Here is the image of how it looks.
I have a tool tip also which shows some data for each region or patch.

I cannot reproduce the example you have shown me above, since I do not have access to the input data. However on a brief inspection you have defined two datasources; source and source1. The x and y fields of both of those are the same objects, and since the patches are working I am assuming you have put in lists of lists?

That works for patches, however the labelset needs specific points as in the example above - you need to calculate the center of each polygon and associate that with the specific label.
