Ok, let me be splicit. I use extensively Spyder with python 3 for my work, I use also LyX to write my articles. When I installed LyX (on windows) it uses its own bundled python2 and it works fine. The problem arises when I want to import my python graphics into LyX, which should be interpreted with python3, I try putting python3 into LyX and then LyX stops working at all!! it doesn't reconfigure anymore, and when I try to start it, it crashes with a big failure. So I am forced to produce python2 only graphics.
to reference this is the article in which I show how to add python graphics within LyX> http://article.gmane.org/gmane.editors.lyx.general/82745/match=python+graphics
