using trace module in enthought


I am using enthought for python. Trace module seems to be very useful for my work but somehow I am unable to make it work.

When I use the following option, I get the following error:
%run -m trace  --trace "D:/Projects/Initiatives/machine learning/programs/debug_1.py"
UsageError: option --trace not recognized ( allowed: "nidtN:b:pD:l:rs:T:em:G" )

%run -m trace  --trace "D:/Projects/Initiatives/machine learning/programs/debug_1.py" --trace
UsageError: option --trace not recognized ( allowed: "nidtN:b:pD:l:rs:T:em:G" )


 %run -m trace "D:/Projects/Initiatives/machine learning/programs/debug_1.py" --trace
