So I have installed that and now get to line 6 with python2, can't find
tkinter *. It is not installed & not available.
Uppercased the name to Tkinter, and I did get it to run, and it opens a
white screen with the menu stuff but no video.
Trace from the launching screen:
gene@GO704:~/linuxcnc$ python python_opencv_camera_example_with_gui.py
Exception in Tkinter callback
Traceback (most recent call last):
File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 1437, in __call__

File "python_opencv_camera_example_with_gui.py", line 92, in show_video
imgtk = ImageTk.PhotoImage(image=img)

self.paste(image)
File "/usr/local/lib/python2.7/dist-packages/PIL/ImageTk.py", line 180,
in paste
from PIL import _imagingtk
ImportError: cannot import name _imagingtk
And with my lack of python knowledge, no clue how it got renamed with the
leading _.
With pillow installed, locate says:
gene@GO704:~/linuxcnc$ locate imagingtk
/usr/lib/pyshared/python2.6/PIL/_imagingtk.so
/usr/lib/pyshared/python2.7/PIL/_imagingtk.so
/usr/lib/python2.6/dist-packages/PIL/_imagingtk.so
/usr/lib/python2.7/dist-packages/PIL/_imagingtk.so
Subtle syntax error? ENV path? Obviously IDK.
I also ran the old script, still works fine.

Thank you Rainer.
