The OrderedDict class wasn't added until Python 2.7. If you're using 2.6, you need to add the following OrderedDict class to the top of the inspyred/ec/utilities.py file (just after the import statements):
try:
import collections.OrderedDict as OrderedDict
except ImportError:
# Backport of OrderedDict() class that runs on Python 2.4, 2.5, 2.6, 2.7 and pypy.
# Passes Python2.7's test suite and incorporates all the latest updates.

Hi,
I am trying to use inspyred in a project involving neuronal parameter optimization.
Installation (using python 2.6.5 on a 64-bit Linux machine) appeared to be successful; however, when I try to use the inspyred module, I get:
>>> import inspyred
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.6/site-packages/inspyred/__init__.py", line 21, in <module>
from inspyred import benchmarks
File "/usr/lib/python2.6/site-packages/inspyred/benchmarks.py", line 27, in <module>
from inspyred import ec
File "/usr/lib/python2.6/site-packages/inspyred/ec/__init__.py", line 45, in <module>
import inspyred.ec.utilities
File "/usr/lib/python2.6/site-packages/inspyred/ec/utilities.py", line 35, in <module>
class BoundedOrderedDict(collections.OrderedDict):
AttributeError: 'module' object has no attribute 'OrderedDict'
Could anyone help me figure out what is going wrong?
Thank you,
Szabolcs
