What is the expected output?

{'memory_percent': 0.0}

What do you see instead?

AttributeError: 'Process' object has no attribute 'memory_percent'

What version of psutil are you using? What Python version?

psutil.__version__
Out[36]: '0.6.1'

On what operating system? Is it 32bit or 64bit version?

Ubuntu 12.04 64bit
