Python Bokeh: Internal Server Error

Question

I've been trying this simple example of embedding in Bokeh - that is, embedding a simple bokeh-based graph onto a html file. When I navigate to localhost:5000, it throws up an internal server error webpage on my browser.

Normally, I wouldn't post anything here without some records of what I've tried, but there's nothing to try. This is the simplest example of embedding, which I'm trying to learn, and it's not working.

Answer 1

If i just download that file, and add debug=True to the call to app.run then it shows an actual exception:

jinja2.exceptions.TemplateNotFound: embed.html

If you look in the directory on GitHub you can see there is also a templates directory with the embed.html in it. Did you copy the example file without also copying the accompanying (and necessary) templates directory?
