title: How can I get descriptive statistics of a NumPy array?
body: <p>I use the following code to create a numpy-ndarray. The file has 9 columns. I explicitly type each column:</p>
  
  <pre><code>dataset = np.genfromtxt("data.csv", delimiter=",",dtype=('|S1', float, float,float,float,float,float,float,int))
  </code></pre>
  
  <p>Now I would like to get some descriptive statistics for each column (min, max, stdev, mean, median, etc.). Shouldn't there be an easy way to do this?</p>
  
  <p>I tried this:</p>
  
  <pre><code>from scipy import stats
  stats.describe(dataset)
  </code></pre>
  
  <p>but this returns an error: <code>TypeError: cannot perform reduce with flexible type</code></p>
