title: No module named numpy.core.multiarray
body: <p>This is the script I am working with</p>
  
  <pre><code># this script starts in powershell so I change the directory to Python27
  
  os.chdir("/Python27/"
  
  #print cwd as a check 
  print os.getcwd()
  
  import nltk
  
  text = nltk.work_tokenize("thanks, Chuck and it's always nice when you get Brian's name corrected, it shows how closely we .....blah blah blah")
  
  #print text as a check
  print text
  
  nltk.pos_tag(text)
  </code></pre>
  
  <p>The script will print text, but it is followed immediately by an Import Error </p>
  
  <pre><code>Import Error message is as follows;
  
  Traceback (most recent call last):
    File "calls_1.txt", line 15, in &lt;module&gt;
  
       nltk.pos_tag(text)
  
    File "C:\Python27\lib\site-packages\nltk\tag\__init__.py", line 99, in pos_tag
      tagger = load(_POS_TAGGER)
  
    File "C:\Python27\lib\site-packages\nltk\data.py"' line 605, in load 
      resource_val = pickle.load(_oopen(resource_url))
  
  ImportError: No module named numpy.core.multiarray
  </code></pre>
  
  <p>However, it appears that the multiarray module is present. This is the result from <code>sys.path</code></p>
  
  <pre><code>&gt;&gt;&gt; for pth in sys.path:
  ...   print pth
  ...
  
  C:windows\system32\python27.zip
  C:\Pthon27\DLLs
  C:\Python27\lib
  C:\Python27\lib\plat-win
  C:\Python27\lib\lib-tk
  C:\Python27
  C:\Python27\lib\site-packages
  &gt;&gt;&gt;
  </code></pre>
  
  <p>Within the <code>C:\Python27\lib\site-packages</code> directory there are the following directories:</p>
  
  <pre><code>nltk
  nltk-2.0.4-py2.5.egg-info
  numpy
  yaml
  yaml.pyd
  PyYAML-3.10-py2.7.egg-info 
  README.txt
  </code></pre>
  
  <p>within the numpy directory there are the following directories</p>
  
  <pre><code>core
  fft
  lib         
  lnalg                 
  random
  </code></pre>
  
  <p>within the core directory there are the following pyd files</p>
  
  <pre><code>_dotblas.pyd
  _sort.pyd
  multiarray.pyd
  scalarmath.pyd
  umath.pyd
  </code></pre>
  
  <p>So it appears that multiarray is present but is not found.</p>
  
  <p>Any suggestions as to how I should proceed to correct the script is appreciated.</p>
