title: How do I use Numpy in Python IDLE?
body: <p>Variations of this question have been asked, but the answers always start from scratch (i.e. from installing numpy).</p>
  
  <p>I already have numpy installed on my computer from an earlier time when I downloaded Anaconda.</p>
  
  <p>If I try to install numpy again using <code>pip install numpy</code>, I get a long error like, the end of which looks like</p>
  
  <pre><code>Command C:\Python27\python.exe -c "import setuptools, tokenize;__file__='c:\\users\\imray~1\\appdata\\local\\temp\\pip_build_Imray\\numpy\\setu
  p.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record c:\users\imray~1\appd
  ata\local\temp\pip-smduhf-record\install-record.txt --single-version-externally-managed --compile failed with error code 1 in c:\users\imray~1\appdat
  a\local\temp\pip_build_Imray\numpy
  Storing debug log for failure in C:\Users\Imray\pip\pip.log
  </code></pre>
  
  <p>numpy works fine when I open <code>cmd</code> from inside the <code>Anaconda</code> folder and command <code>import numpy</code>. But it won't work from IDLE even if I navigate to said folder (via <code>os.chdir('C:\Anaconda')</code>) and issue the same command. </p>
  
  <p>How do I get numpy to work in IDLE?</p>
