title: Pyinstaller numpy "Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll"
body: <p>I'm new with python apps. I'm trying to build my python GUI app with pyinstaller.
  My app depends on the following packages: PyQt4, numpy, pyqtgraph, h5py.
  I'm working with WinPython-32bit-3.4.4.1.</p>
  
  <p>I build the app with this command:</p>
  
  <pre><code>pyinstaller --hidden-import=h5py.defs --hidden-import=h5py.utils --hidden-import=h5py.h5ac --hidden-import=h5py._proxy VOGE.py
  </code></pre>
  
  <p>I launch my app with the exe file in the dist directory created by pyinstaller and it seems work fine until the program call numpy and crash with this error:</p>
  
  <p>Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll</p>
  
  <p>The mkl_intel_thread.dll is not present in the software directory; but with the file copied in the root dir of the program I got the same error</p>
  
  <p>Thanks for your help</p>
