Hi all, Sorry to disturb all, it may be very simple problem but I am very new on msnoise and mysql so it seems I need some help. I created an MySQL database. I did "msnoise install" than "msnoise config" and I received the following error message as below; ..... File "/usr/lib64/python2.7/site-packages/matplotlib/pyplot.py", line 98, in <module> _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup() File "/usr/lib64/python2.7/site-packages/matplotlib/backends/__init__.py", line 28, in pylab_setup globals(),locals(),[backend_name],0) ImportError: No module named backend_qt4agg when I tried to easy_install this module I also had the following error; [root@localhost site-packages]# easy_install backend_qt4agg Searching for backend-qt4agg Reading https://pypi.python.org/simple/backend_qt4agg/ Reading https://pypi.python.org/simple/backend-qt4agg/ Couldn't find index page for 'backend_qt4agg' (maybe misspelled?) Scanning index of all packages (this may take a while) Reading https://pypi.python.org/simple/ No local packages or download links found for backend-qt4agg error: Could not find suitable distribution for Requirement.parse('backend-qt4agg') I appreciate if anybody could help.
