title: Trouble reading npy file
body: <p>I am new to python and am having trouble reading a *.npy file that somebody else saved.  If I use the following commands:</p>
  <pre><code>import numpy as np
  np.load('lat.npy')
  </code></pre>
  <p>I get the following error:
  <code>ValueError: Cannot load file containing pickled data when allow_pickle=False</code></p>
  <p>So, I set allow_pickle=True:
  <code>np.load('lat.npy',allow_pickle=True)</code></p>
  <p>Then, I get a different error:
  <code>OSError: Failed to interpret file 'lat.npy' as a pickle</code></p>
  <p>Maybe it is relevant that I am on a PC, and the other file was written on a Mac.</p>
  <p>Am I doing something wrong?  (I am sorry if this question has been asked already.)  Thank you!</p>
