I can run python and sage program.
Plotting with sage is working
plot(x^3) draw the correct
figure<https://github.com/sagemath/sagecell/blob/master/contrib/vm/install-sagecell-functions#L111>
however matplotlib is not working
import pylab
pylab.plot(X,Y)
pylab.show()
result in the following error TCLTK error (log followed)
TclError: no display name and no $DISPLAY environment variable
Have you any idea
THanks
Marc
