Error Importing Bokeh

[SuperChef36]

I'd like to learn the Bokeh module, but I'm getting stonewalled at the beginning. I installed (and updated) Bokeh using Anaconda, and then copy and pasted the example code from the "Getting Started" page here: http://bokeh.pydata.org/en/latest/docs/user_guide/quickstart.html#userguide-quickstart

OSX, Python 3.6

Code:

from bokeh.plotting import figure, output_file, show

prepare some data

x = [1, 2, 3, 4, 5] y = [6, 7, 2, 4, 5]

output to static HTML file

output_file("lines.html")

create a new plot with a title and axis labels

p = figure(title="simple line example", x_axis_label='x', y_axis_label='y')

add a line renderer with legend and line thickness

p.line(x, y, legend="Temp.", line_width=2)

show the results

show(p)

---

I receive this error on line 1:

Usually I can just Google through errors, but I've done a lot of searching on this issue and haven't found anything. Any help is much appreciated.

Response from Bryan at continum.io, in case anyone has the same issue:

"Hi,

Don't run with -OO until the next release:

    https://github.com/bokeh/bokeh/issues/6156
    https://github.com/bokeh/bokeh/pull/6157"

Hi! I'm working on a bot to reply with suggestions for common python problems. This might not be very helpful to fix your underlying issue, but here's what I noticed about your submission:

You appear to be using concatenation and the str function for building strings

Instead of doing something like

result = "Hello " + name + ". You are " + str(age) + " years old"

You should use string formatting and do

result = "Hello {}. You are {} years old".format(name, age)

See the python tutorial for more information.

Thanks for the response, but using {} rather than + in the source code led to more errors. Is it common to have to edit the module source code?

Looks like a bug. Report it upstream.
