No, it's a syntax error in the script itself, at least under the version of Python you're using. > My connad prompt call and the computer's response look like this: > > C:\Users\Adam\Desktop\JBOOST\jboost-2.2\jboost-2.2\scripts>nfold.py > nfold.py > File "C:\Users\Adam\Desktop\JBOOST\jboost-2.2\jboost-2.2\scripts > \nfold.py", line 13 > print 'Usage: nfold.py <--booster=boosttype> <--folds=number> [-- > generate | --dir=dir] [--data=file --spec=file] [--rounds=number -- > tree=treetype]' > > ^ > SyntaxError: invalid syntax You're probably running Python 3.x, which changed `print` from a keyword to just a regular function; hence, `print foo` is illegal, and one must write `print(foo)` instead. Based on this, I'd say that nfold.py was written for Python 2.x rather than Python 3.x; so you'll either need to port it to Python 3.x, or install Python 2.x and run it under that.
