title: PyInstaller what are hiddenimports and hooks?
body: <p>I recently tried pyInstaller and there are some things i don't quite get. i have been trying to create some executables (NOTE: all of them use numpy, scipy, OpenCV, BLAS etc) but i have been failing. There is always something missing. So my question is, can someone explain better to me what are hiddenimports and hooks, and how can i tell pyInstaller the directories of all the dependencies in my code so it can pack the in the final executable.</p>
  
  <p>Thank you.</p>
