graphlab.SFrame.show() Error: Requested port is unavailable: None

Question

upon entering the command:

graphlab.show(); 

I get the following error:

Error: Requested port is unavailable: None

So, I tried to set the port by typing:

gl.canvas.set_target('ipynb', 8888). 

But not fruitful. I checked the open ports in ubuntu terminal and assigned it different points (among some confirmed open ports) but it's not working anyways.

I am using python jupyter notebook in browser through pycharm.

Answer 1

Try downgrading tornado:

pip install tornado==4.5.3

(replace pip with conda if you are using Anaconda)

Using

gl.canvas.set_target('ipynb')

without setting a port should then be enough.

Answer 2

The answer of OSError [Errno 99] - python applies here also.

If it works using the ip address but not using hostname.

Removing double localhost in /etc/hosts should be solution. hosts file should look something like this (mapping ip to hostname)

127.0.0.1   localhost
127.0.1.1   your_hostname_here

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
