import wx fails with file not found error

Aydin · July 6, 2018, 5:28pm

I’m running to an issue with Python 3 and wx version 4.0.3

File “”, line 1, in File “/usr/local/lib/python3.4/dist-packages/wx/init.py”, line 17, in from wx.core import * File “/usr/local/lib/python3.4/dist-packages/wx/core.py”, line 12, in from ._core import * ImportError: /usr/local/lib/python3.4/dist-packages/wx/_core.cpython-34m.so: cannot open shared object file: No such file or directory

The file is in the directory.

I followed the install direction for raspbian from:

https://wiki.wxpython.org/BuildWxPythonOnRaspberryPi

If that file exists (_core.cpython-34m.so), then this almost always
means you are missing one of the prerequisite packages. Did you
apt-get the whole list in the middle of that page?

Hi Tim,

I got the same problem, too after installing wxpython.

My computer system is Window 7.

"import wx

ModuleNotFoundError: No module named ‘wx’"

Do you have any suggestion?

Thank you!

How did you do the install? If you have more than one Python or Python virtual environment on your computer, are you sure it was installed into the same Python you are testing with?

HI, I have been down this path >1x with eventual success. The attached doc shows how. Where I departed from the published script is in bold font. I used the installed Python3.5 and did not create a virtual environment (because I do not yet understand that).
Thedemo is beautiful. Graham.

No, it's not the same problem.

My computer system is Window 7.
"import wx
ModuleNotFoundError: No module named 'wx'"

How, EXACTLY, did you install wxPython?

There are many ways to screw this up. If you have both Python 2 and Python 3, perhaps you installed one, but your default command line bring up the other.

Hi Tim,

My computer has only one Python version which is 3.6. And I used the following at command line:

pip install wxpython

Can you run the following commands and show the output?

 pip \-V
 pip3 \-V
 python \-V

It showed:

site-packages\pip <python 3.7> when typing pip3 -V
Python 3.7.0 when typing python -V

No it did not.

If you want to learn start by learning to follow instructions
first, *then* second guess on their meaning.

Additionally, it may be the libpng12-0 problem, which is reported by _core as missing. I was initially under impression that the _core itself is missing (the error message is somewhat ambiguous). Since this is my third time that I’m hunting for ways to simply install wx, I had my notes ready… and it mostly worked except this. But I had that in my notes too, so went to this place and downloaded exactly what it said and it all works now.

Hi Robin i have two versions of python but im running the python3 version beacuse i converted the python2 code to python3 and also installed the wxPython on the same environment of python3 version can you help what other error it might be
