PyInstaller and Kivy builds but doesn't run

Question

I am trying to create a windows.exe from a kivy project. I have followed the guide from PyInstaller https://kivy.org/doc/stable/guide/packaging-windows.html I am able to build the app following the commands, edit the spec file and use it to compile the.exe All of the directories are created and no errors occur however, when I run the application.exe it launches a command prompt and then closes again. This is my first time utilising Pyinstaller and kivy so Im hoping I am just missing something simple.

# -*- mode: python ; coding: utf-8 -*-
from kivy_deps import sdl2, glew

block_cipher = None


a = Analysis(['C:\\Users\\thoma\\PycharmProjects\\FacesGUI\\main.py'],
             pathex=['C:\\Users\\thoma\\PycharmProjects\\FacesGUI\\exe'],
             binaries=[],
             datas=[],
             hiddenimports=[],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          [],
          exclude_binaries=True,
          name='FacesGUI',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          console=True )
coll = COLLECT(exe, Tree('C:\\Users\\thoma\\PycharmProjects\\FacesGUI\\'),
               a.binaries,
               a.zipfiles,
               a.datas,
           *[Tree(p) for p in (sdl2.dep_bins + glew.dep_bins)],
               strip=False,
               upx=True,
               upx_exclude=[],
               name='FacesGUI')

I am uncertain what kivy dependencies I need to include in the.spec file I have followed the example re: sdl2, glew etc... Is there a way to trace the.exe when I run it to try troubleshoot the error?

I have run the.exe as suggested and it appears there is an issue with the face_recognition import.

How do I include the face_recognition package? is this achieved through the.spec Collect section?

Answer 1

I copied all of the packages from the python directory into the main directory (ie the location of the.exe and.py etc) in my case this was the face_recognition libraries.
