Fix Anaconda Spyder kernel connection problem

Download and install Anaconda for Window:

https://www.continuum.io/downloads


When starting spyder the iPython console is unable to connect to kernel. The console displays:

'import sitecustomize' failed; use -v for traceback
Assertion failed: Socket operation on non-socket (bundled\zeromq\src\select.cpp:185)

What happens when you run in a terminal

jupyter qtconsole

Do you see the same problem?   ------ YES

this seems to be a problem with pyzmq. Do you know something about it?

conda install pyzmq=15.4.0   (latest version)

and try again with

jupyter qtconsole

It works.
