I need to convert a numpy array to a QtGui.QImage. But I don't know how to do that. I've find this : http://kogs-www.informatik.uni-hamburg.de/~meine/software/qimage2ndarray/ but when I try to install this I get an error :
michael@michael-laptop-ubuntu:~/rubyWorkSpace/pymcs$ easy_install
error: No urls, filenames, or requirements specified (see --help)

I don't understand this error because obviously import numpy works...
If anyone knows an other way to convert numpy array to QImage it could be great. Thanks.
The traceback shows that you are trying to install the package using the easy_install installed under the USER_BASE directory (~/.local/bin/easy_install).
This is in turn using the python installed under /opt/ActivePython-2.7, which presumably doesn't have the numpy package installed.
However, it appears that your system python (/usr/lib/python2.7), does have the numpy package installed.
So to fix the error, first install the ubuntu package which includes easy_install:
sudo apt-get install python-setuptools
And then do either:
/usr/bin/easy_install --user qimage2ndarray
to install qimage2ndarray to your USER_SITE directory, or:
sudo /usr/bin/easy_install qimage2ndarray
to install it so that it is available system-wide.
