Python version number mismatch

I’ve been trying to use the program youtube-dl-gui. It runs but doesn’t do anything useful. Following a suggestion from Knurpht, I called it from a shell and got this:

/usr/lib64/python2.7/site-packages/wx-3.0-gtk2/wx/ UserWarning: wxPython/wxWidgets release number mismatch
  warnings.warn("wxPython/wxWidgets release number mismatch")

Knowing little about Python, particularly in this context, where should I go from here?

  1. Make sure of the consistency of your system, that your packages and files are as up to date as possible, and then that your installation is freshly from a repository.
    You can accomplish all this by simply updating your system, the simplest and most certain is by using zypper
zypper update

Of course, that assumes that you are installing from your openSUSE repositories and not from somewhere else.
If necessary,this is the software search for your app


See Knurpht’s reply in your other thread for the same issue.

When trying to install I get:

erlangen:~ # zypper in youtube-dl-gui
Loading repository data...
Reading installed packages...
Resolving package dependencies...

Problem: nothing provides python-wxWidgets-3_0 needed by youtube-dl-gui-0.4-1.8.noarch
 Solution 1: do not install youtube-dl-gui-0.4-1.8.noarch
 Solution 2: break youtube-dl-gui-0.4-1.8.noarch by ignoring some of its dependencies

Choose from above solutions by number or cancel [1/2/c/d/?] (c): 
erlangen:~ # 

This is solid evidence for a problem with the package. You may search for alternatives:
