Re: [Visualpython-users] vpython and ipython

[Michele M. <mat...@gm...>]

Hi all,

Visual use a gtk main loop to manage the display.

the ipython -gthread switch will do the trick.

Using the pylab switch instead will start the pylab interface using the
backend configured on your matplotlib (~/matplotlib/matplotlibrc on Linux.)

On ubuntu the default backend is gtk so

ipython -gthread
or

ipython -pylab

has the same effect, except some numpy function which are directly imported
in the global namespace.

HTH,
Michele.
