Date Entry


12.10.2012 Full install of mousetrap complete. Config file was manipulated to include failed dependency on 'python-opencv' which has been updated and the package is now referred to as 'cv'. Other dependencies are outdated or the names have been changed as well (xlib-python, etc). New errors with 'gobject' have been identified. Here is the recorded error when running mousetrap: 


 ImportError: could not import gobject
 (error was: ImportError('When using gi.repository you must not import static modules like "gobject".
 Please change all occurrences of "import gobject" to "from gi.repository import GObject".',))

Will attempt to remove instances of broken dependency opencv to the newer cv


12.17.2012 Bug for pygobject is here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=649861
  • The fix is to upgrade to version 3 of gtk?
  • Changed line in configure.in file to AM_CHECK_PYMOD(cv,,,[AC_MSG_ERROR(Could not find python module cv)]) to fix opencv problem when creating make files
  • Highgui no longer exists in the new API for cv (once known as opencv) and it should just be called as cv.whatever.
  • cvCreateCameraCapture() no longer exists, replaced with cv.CaptureFromCAM().

New Error

Will look into gtk and GObject for error


12.19.2012
  • In this particular file: widgets.py, we actually want to import gobject directly and type_register the Mapper using gobject. After doing this, I have the Window pop up and now a new error has come up.

  • Changed line 335 in _ocv.py to import cv2

c = cv2.CascadeClassifier('haarcascade.xml')

  • Changed line 125 in _ocv.py to frame = co.hg.QueryFrame( self.capture ) 
 _ocv needs to change many dependencies for the new api
  • Changed import in widgets.py to 'import gobject' and changed to 'gobject.register_type(Mapper)'

I have no other error besides this: 

 /usr/lib/python2.7/site-  packages/gobject/constants.py:24: Warning:   g_boxed_type_register_static: assertion   `g_type_from_name (name) == 0' failed
 import gobject._gobject

and this: 

 (mousetrap:19550): Gtk-WARNING **: Unable to locate theme engine in module_path: "clearlooks",


I believe this is explained in this reported bug: https://bugs.launchpad.net/bzr-gtk/+bug/923824

  • There is a whole big issue with dependencies surrounding pygobject, pygtk, and gtk that are causing errors.

  • Was successfully able to fix opencv issue by changing the single line "import opencv" in "configure" to be "import cv".
  • When trying to run mousetrap receiving error "ImportError: No module named mousetrap.app.main"
    • As Amber had mentioned, must be in the src directory before running the "mousetrap" command. Thank you =]
      • >> Fix: Are you in the src directory when you run the command 'mousetrap', for the moustrap.app.main error? (Amber)

12/16/12

  • ImportError: could not import gobject (error was: ImportError('When using gi.repository you must not import static modules like "gobject". Please change all occurrences of "import gobject" to "from gi.repository import GObject".',))
    • Changed all instances by running 
grep -rl 'import gobject' ./ | xargs sed -i 's/import gobject/from gi.repository import GObject/g
  • Then changed all instances of gobject to GObject with command 
grep -rl 'gobject' ./ | xargs sed -i 's/gobject/GObject/g

    • Removed cv.cvXXX in _ocv.py to cv.XXXX (Methods no longer start with cvXXX)
  • Now have error of 
Camera instance has no attribute 'small_img'

1/4/12

  • It appears that the error is appearing becuase there is no image being captured from the webcam. I am working on trying to figure out why that is.
