title: Pyinstaller Failed to import module __PyInstaller_hooks_0_pydoc
body: <p>I am trying to build a screen reader in python3.6.9 as a college assignment.</p>
  <p>The python script works fine but when I try to create an app out of it using PyInstaller 4.3, it shows error message:</p>
  <blockquote>
  <p>`PyInstaller.exceptions.ImportErrorWhenRunningHook: Failed to import
  module __PyInstaller_hooks_0_pydoc required by hook for module
  /.../site-packages/PyInstaller/hooks/hook-pydoc.py.</p>
  <p>Please check whether module __PyInstaller_hooks_0_pydoc actually
  exists and whether the hook is compatible with your version of
  /.../site-packages/PyInstaller/hooks/hook-pydoc.py:`</p>
  </blockquote>
  <p>It also shows many warnings while building the executable.</p>
