Andrew,
There were a few minor syntax errors with the source code that you
corrected. I am listing them below.
Do incorporate these corrections in the new VE version.
if hasattr(sys.'argv') and sys.executable == sys.argv[0]: # Windows binary
Line 101 of config.py should be* "if hasattr(sys, 'argv')"*
if hasattr(sys,'argv'): and not sys.argv[0]: # Interactive mode
Line 108 of __init__.py should be *"if hasattr(sys,'argv') and not
sys.argv[0]:"
*After these corrections, I could import the VisionEgg package into LabPython.
But as you guessed it is creating problems elsewhere as well. For
Example, I can import Screen and get_default_screen.
But using get_default_screen anywhere in the code causes the same
attribute error.
I am trying to work on it and figure out a way, but any help you could
offer would be very useful.
Thanks for the prompt response.
Best,
Chintan
