Hi,
I've been following your tutorial to learn structure from sample data.
http://www.openbayes.org/tutorials/learning-the-structure-of-a-bn-from-sample-data
The file StructLearning.py doesn't exist in the Examples directory, and creating the file by hand results in the following error:


File "C:\Python25\Lib\site-packages\OpenBayes\learning.py", line 194, in __init__
self.BNet = BNet.copy()
AttributeError: 'BNet' object has no attribute 'copy'

This occurs at the following point:
# Learn the structure
struct_engine = learning.GreedyStructLearningEngine(G2)

I came back to the example as I was using my own test data set and thought it might have been that which was causing the error.

As you can see i'm doing this on a windows box

I'd appreciate any help with this, I'm not really a python person
I've looked into learning.py and copy is defined so I'm at a loss...
Thanks,

Chris

Bugger this was meant to go into the bugs section, sorry.

Never mind I've made some changes to learning.py altering BNet.copy() to copy.copy(BNet) and its associates, which appears to have solved the problem.
