执行时GraphLab创建sFrame.show（）函数错误

Question

I've installed GraphLab Create using Anaconda. Everything seems to be fine with SFrames, I can manipulate data and ingest it but I can't execute the function show() . The error message is like this:

Error: Requested port is unavailable
inspect.pyc in find_vars(var)
     42     (variable_name, variable) = _find_variable_name(var)
     43     if variable_name is not None:
---> 44         target.add_variable((variable_name,), variable)
     45     return variable_name
     46 

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

Also, I tried to instead change the target of the canvas to the notebook itself cause the port thing might have caused the problem, but the error when I execute graphlab.canvas.set_target('ipynb') is this:

util.pyc in __new__(cls, *args, **kwargs)
    310         # singleton magic.  If we get rid of that we can switch to __init__
    311         # here too.
--> 312         instance.initialize(*args, **init_kwargs)
    313         return instance
    314 

TypeError: initialize() got an unexpected keyword argument 'io_loop'

Here's the specs of my environment:

Python: 2.7
OS: Windows 10
Jupyter Notebook: 5.4.1
Anaconda: 4.3.30
GraphLab: 2.1

EDIT: Added the error message on top of the stack trace which is Error: Requested port is unavailable

I used Anaconda3 5.1.0 and got a problem similar to yours. Then, I uninsatll it, and download GraphLabCreateLauncher from Turi . Run the launcher and install Anaconda2 4.0.0. Now, the problem is solved. I hope it will help you.
