[Matplotlib-users] wrong numpy version

[Nemanja S. <vla...@gm...>]

Hi all guys,

I am using RHEL6 and I am ploting figures throughout my project, so I
wanted some workaroung blocking show() function call. I have found few
solutions that use multiprocessing, so finally i finished with this:

pool.map(plot_graph, c)

and

def plot_graph(*args):
    plt.figure(args[0][2])
    plt.bar(args[0][1][:-1], args[0][0], width=1)
    plt.show()

But when I have more than one figure the following error occures:


/usr/lib64/python2.6/site-packages/matplotlib/backends/backend_gtk.py:621:
DeprecationWarning: Use the new widget gtk.Tooltip
  self.tooltips = gtk.Tooltips()
/usr/lib64/python2.6/site-packages/matplotlib/backends/backend_gtk.py:621:

  self.tooltips = gtk.Tooltips()

`!xcb_xlib_threads_sequence_lost' failed.
runner.py: Fatal IO error 0 (Success) on X server :0.0.

Since my version of matplolib doesnt support blocking = false solution, I
wanted to install new version. For that I installed new version of numpy
but when i run python setup.py build in matplolib foldet i get following:

Edit setup.cfg to change the build options

When I run python and check numpy version it is indeed 1.8.0, but
matplotlib buils script somehow founded older one.


I would be really happy if somebody can help me overcome problem with many
figures.

Best and cheers
