Thanks a lot, must be getting close now...
I changed the indentation one lines 136-168, and put in the command
window:
nfold.py --booster=Adaboost --folds=5 --data=spambase.data --
spec=spambase.spec --rounds=500 --tree=ADD_ALL --generate
no syntax errors this time, it just said:
nfold.py: Your CLASSPATH is not set. You must place jboost.jar in your
CLASSPATH.
is that the chdir() command in python? and can I somehow set that in
the dos command window?
