wxpython install error

Greetings, i installed wxpython with the comand:
pip install -U \-f
https://extras.wxpython.org/wxPython4/extras/linux/gtk3/fedora-28 \wxPython
Looking in links:
https://extras.wxpython.org/wxPython4/extras/linux/gtk3/fedora-28
For my fedora computer, but after the install completed, i tried to run
import wx and the next error prompted:
>>> import wx
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File
"/home/rodrigo/anaconda2/lib/python2.7/site-packages/wx/__init__.py", line
17, in <module>
    from wx.core import *
  File "/home/rodrigo/anaconda2/lib/python2.7/site-packages/wx/core.py",
line 12, in <module>
    from ._core import *
ImportError: libpng12.so.0: cannot open shared object file: No such file or
directory
>>>
What can i do about it, it says that i dont have that ._core archive  even
when i look for it, i tried to re-install the package but it didn't work,
what can i do, how can i fix this?
From beforehand thank you.
