python 2.7 - pyinstaller exe blank screen (Kivy) -

i've built .exe on windows 10 using pyinstaller. when run executable, window opens doesn't display widgets, blank screen. output doesn't show errors, far can make out. using python 2.7 (enthought canopy) kivy 1.9.1. when run original source file, works perfectly; it's .exe fails.

my .spec file looks this:

# -*- mode: python -*- kivy.deps import sdl2, glew, gstreamer  block_cipher = none  = analysis(['c:\\users\\christiaan\\documents\\lifeq_dp_pp_p\\toolbox\\ui\\data_importer\\phoenixkv.py'],          pathex=['c:\\users\\christiaan\\documents\\phoenix'],          binaries=none,          datas=[('c:\\users\\christiaan\\documents\\lifeq_dp_pp_p\\toolbox\\ui\\data_importer\\dev_ids.json', '.'), ('c:\\users\\christiaan\\documents\\lifeq_dp_pp_p\\toolbox\\ui\\data_importer\\ref_ids.json', '.')],          hiddenimports=['sqlalchemy.ext.hybrid'],          hookspath=[],          runtime_hooks=[],          excludes=[],          win_no_prefer_redirects=false,          win_private_assemblies=false,          cipher=block_cipher) pyz = pyz(a.pure, a.zipped_data,          cipher=block_cipher) exe = exe(pyz,       a.scripts,       exclude_binaries=true,       name='phoenix',       debug=true,       strip=false,       upx=false,       console=true ) coll = collect(exe, tree('c:\\users\\christiaan\\documents\\lifeq_dp_pp_p'),            a.binaries,            a.zipfiles,            a.datas + [('dev_ids.json', 'c:\\users\\christiaan\\documents\\lifeq_dp_pp_p\\toolbox\\ui\\data_importer\\', 'data'), ('ref_ids.json', 'c:\\users\\christiaan\\documents\\lifeq_dp_pp_p\\toolbox\\ui\\data_importer\\', 'data')],            *[tree(p) p in (sdl2.dep_bins + glew.dep_bins)],            strip=false,            upx=false,            name='phoenix') 

and output when running is:

i had same problem , solved copying .kv file dist folder.

cp -r c:/users/ben/documents/opencv_hummingbirdsmotion/motionmeerkat/motionmeerkat.kv dist/main/ 

this may achieved adding .kv spec file data object. blank screen says, know there kivy app, have no widgets.
