Hi David, i have experienced the follow errors despite doing a fresh install with a recovery image provided on the hardware's wiki page.

I noticed that there is this missing node/package "image_view" and some attribute with regards to python 2.7

Can you advise? thanks!

This is a known issue found at http://bugs.python.org/issue14308

Try do a search for these type of issues and see if you hit on any results.

Perform an apt-get upgrade on your python2.7 package and see if the problem goes away. In fact, have you done an apt-get upgrade for the entire system before you proceed with your project ?

thanks for your inputs david, i have tried running the command "sudo apt-get upgrade" and after upgrading, my gui goes haywire and doesnt respond. it also screws up my whole OS and i have to format and reload the recovery image back onto the sd card. do you have any other solutions ?

Then just upgrade the python 2.7 package

sudo apt-get install --only-upgrade python2.7

This command will only update one package and its dependencies

If really this also doesn't work, then you still have 2 choices.

(1) Refer to the http://bugs.python.org/issue14308, and patch the file manually found at /usr/lib/python2.7/threading.py

This is the patch file http://bugs.python.org/file24852/thread.py.patch

(2) Another way is you install a non-system python and run your python script using a non-ssytem copy which is fixed. How, I suspect if just upgrading python 2.7 will corrupt your software, then having your own non-system copy of python may also be the same
