title: multivariate gaussian probability density function python on Mac
body: <p>I'm unable to use SciPy and its modules for calculating the probability density function of a multivariate Gaussian distribution.  I know that such modules exist, but I'm unable to use them (I can't even import scipy: I get the message: <code>ImportError: No module named scipy</code>).</p>
  
  <p>I was wondering if there were any good tool or other way to calculate the pdf of a multivariate Gaussian distribution in python.  Thanks in advance for the help!</p>
