title: How to support numpy, scipy in ironpython 2.7.5
body: <p>I use the numpy,scipy egg package from <a href="https://store.enthought.com/repo/.iron/" rel="nofollow">https://store.enthought.com/repo/.iron/</a> and it behave well in ironpython 2.7.3. in Window 7.
  But ironpython 2.7.5 support pip install flow so I upgrade to this version but it's ok to import numpy in ironpython.</p>
  
  <p>I find the message as follows:</p>
  
  <blockquote>
    <blockquote>
      <blockquote>
        <p>import numpy
            Traceback (most recent call last):
             File "", line 1, in 
             File "D:\MyDoc\Training_Course\ISP\IronPython-2.7.5\IronPython-2.7.5\lib\site-
            packages\numpy__init__.py", line 155, in 
             File "D:\MyDoc\Training_Course\ISP\IronPython-2.7.5\IronPython-2.7.5\lib\site-

            ImportError: No module named NumpyDotNet</p>
      </blockquote>

  <p>so I copy IronPython-2.7.5\DLLs*.dll to IronPython-2.7.5 folder and solve the NumpyDotNet module not found issue but one more issue occurs and I list as follows:</p>

  WRN: Assembly binding logging is turned OFF.
  To enable assembly bind failure logging, set the registry value [HKLM\Software\M
  icrosoft\Fusion!EnableLog] (DWORD) to 1.
  Note: There is some performance penalty associated with assembly bind failure lo
  gging.
  To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fus
  ion!EnableLog].

  <p>I ever asked Enthought support, and their response is no plan to upgrade it any more. They suggested me to ask possible support in this forum 
  So can anyone have the solution to solve the issue I met ? </p>
  
  <p>Thanks for you in advance.</p>
