I'm trying to run in ipython notebook but I keep getting the following error: ` Error: Requested port is unavailable: None

AttributeError Traceback (most recent call last) <ipython-input-3-f6d537836882> in <module>() ----> 1

AttributeError: 'NoneType' object has no attribute 'add_variable' `

Also, trying to set graphlab.canvas.set_target('browser')

results is a similar error : Error: Requested port is unavailable: None

What can cause this ?

Thanks !

Are you trying to run canvas on your local browser? Please try the following command and set a different port number. Let us know if it does not resolve the issue. <pre> graphlab.canvas.settarget('browser',portnum) </pre>

It's possible that there is a Tornado bug preventing our code from binding to localhost on any port (I have seen this once before). Can you try posting the stack trace from the set_target error? I think the stack trace from show (posted above) is a red herring, a symptom caused by the first error.
