title: How to import NumPy in the Python shell
body: <p>I have tried importing NumPy in Python, but it did not succeed:</p>
  
  <pre><code>&gt;&gt;&gt; import numpy as np
      x=np.array([[7,8,5],[3,5,7]],np.int32)
  
     Traceback (most recent call last):
     File "&lt;pyshell#3&gt;", line 1, in &lt;module&gt;
     import numpy as np
     File "C:\Python27\lib\numpy\__init__.py", line 127, in &lt;module&gt;
     raise ImportError(msg)
     ImportError: Error importing numpy: you should not try to import numpy from
     its source directory; please exit the numpy source tree, and relaunch
     your Python interpreter from there.
  </code></pre>
  
  <p>How can I fix this?</p>
