title: Importing Scipy Signal (Windows)
body: <p>I am currently trying to get the signal package from Scipy to play nice, but I am having troubles importing. Here is my code</p>
  
  <pre><code>import plotly.offline as pl
  import plotly.graph_objs as go
  import numpy as np
  from scipy import signal
  
  t = np.linspace(0, 10, 5001)
  w = chirp(t, f0=12.5, f1=2.5, t1=10, method='logarithmic')
  
  # Create a trace
  trace = go.Scatter(
      x = t,
      y = w
  )
  
  data = [trace]
  
  # Plot
  pl.plot(data, filename='basic-line.html')
  
  # or plot with: plot_url = py.plot(data, filename='basic-line')
  </code></pre>
  
  <p>and here is the error it is throwing me</p>
  
  <pre><code>Traceback (most recent call last):

  </code></pre>
  
  <p>I could not directly install numpy or scipy from PIP so I used the whl files from <a href="http://www.lfd.uci.edu/~gohlke/pythonlibs/" rel="nofollow">here</a>.</p>
  
  <p>System:</p>
  
  <ul>
  <li>Windows 10 64-bit </li>
  <li>Python 3.5.1 64-bit</li>
  </ul>
  
  <p>Perhaps a build problem?</p>
