title: Python scikits - Buffer has wrong number of dimensions (expected 1, got 2)
body: <p>I am trying this code snippet. I am using scikits.learn 0.8.1</p>
  
  <pre><code>from scikits.learn import linear_model
  import numpy as np
  num_rows = 10000
  X = np.zeros([num_rows,2])
  y = np.zeros([num_rows,1])
  # assume here I have filled in X and y appropriately with 0s and 1s from the dataset
  clf = linear_model.LogisticRegression()
  clf.fit(X, y)
  </code></pre>
  
  <p>I am getting this -->  </p>
  
  <pre><code>/usr/local/lib/python2.6/dist-packages/scikits/learn/svm/liblinear.so in scikits.learn.svm.liblinear.train_wrap (scikits/learn/svm/liblinear.c:992)()
  
  ValueError: Buffer has wrong number of dimensions (expected 1, got 2)
  </code></pre>
  
  <p>What is wrong in here?</p>
