My intellij version is 15.0.2. But in the run context menu, there is no option regarding profiling a piece of code. 
Anyone knows what goes wrong?
The Python profiler does not show up in IntelliJ IDEA Ultimate, if the UML plugin is not enabled. At least this worked for me. I had the same issue and asked JetBrains directly.
