title: Python: Buffer dtype mismatch, expected 'intp_t' but got 'long'
body: <pre><code>import numpy as np
  from fastkde import fastKDE
  import pylab as PP
  
  #Generate two random variables dataset (representing 100000 pairs of datapoints)
  N = 2 * 10**5
  var1 = np.array(50*np.random.normal(size=N) + 0.1)
  var2 = np.array(0.01*np.random.normal(size=N) - 300)
  
  #Do the self-consistent density estimate
  myPDF,axes = fastKDE.pdf(var1,var2)
  </code></pre>
  
  <p>I get this error </p>
  
  <pre><code> ValueError: inputArray does not appear to be array like.  Error was: Buffer dtype mismatch, expected 'intp_t' but got 'long' 
  </code></pre>
  
  <p>What is intp_t data type? How do I correct this??? Am new to Python. </p>
  
  <p>On line numbers, etc. attached is the 2 page output of my jupyter notebook:
