Spyder/Pythonxy crashes

Question

Upon installing python xy 2.7.5 on my laptop, I tried to launch the Spyder IDE. This yielded the following error:

C:\Python27\Scripts>spyder.exe
Traceback (most recent call last):
  File "C:\Python27\Scripts\spyder-script.py", line 9, in 
    load_entry_point('spyder==2.2.0', 'console_scripts', 'spyder')()

Using a python console, I was able to run python code as well as matplotlib and numpy code. Ipython works, however Ipython (Qt) does not work. what could be the reason for this?

The host OS is Windows XP.

Answer 1

This is actually a problem with the most recent builds of zeromq, which are messaging libraries that are required for IPython, and not with Spyder itself. The latest zeromq builds are not compatible with Win XP. This is a know issue with recent versions of Python(x,y) on Win XP which can be solved by following the guidance in this bug report.

Answer 2

It works by installing https://pythonxy.googlecode.com/files/pyzmq-13.0.2-4_py27.exe and http://h5py.googlecode.com/files/h5py-2.1.3.win32-py2.7.msi ,
