I am trying to install GNU octave for use in python oct2py. I have been using octave 3.6.4 alone for several months without problems but I cannot call functions octave scripts from python. While in python:

 import oct2py

I get the error message:

 Please install GNU Octave and put it in your path

my path has the following additions to the system variables:

 C:\Program Files\Java\jdk1.7.0\bin;;C:\Python27\;C:\Octave-3.6.4\mysys

I am wondering if 'GNU Octave' is different to the version of octave that I have installed? Or if there is something additional that I am not doing?

After changing the path to bin the following error ocurs in the python shell:

 >>> oc = oct2py.Oct2Py()

Traceback (most recent call last):
  File "<pyshell#19>", line 1, in <module>
    oc = oct2py.Oct2Py()
