This is Fedora with python3-wxpython4-4.0.6-8 installed.
I tried a sample from the wxpython website:
#!/usr/bin/env python3
# First things, first. Import the wxPython package.
import wx
# Next, create an application object.
app = wx.App()
# Then a frame.
frm = wx.Frame(None, title="Hello World")
# Show it.
frm.Show()
# Start the event loop.
app.MainLoop()
and got
ImportError: bad magic number in 'wx': b'\x03\xf3\r\n'
Any ideas?
If I understand this correctly it means that the Fedora package is in error. As I don’t want to mess around with the package in /usr/lib64/python3.7/site-packages/wx/ I cannot use wxPython for now.
Hopefully, the Fedora package gets fixed soon. Perhaps I find out where I could report a bug regarding the Fedora package.
I tried to work around but without success:
python3-wxpython4 and python3-wx-siplib
python3-pathlib2
wxPython for my user which is sufficient for the time being:pip-3 install --user wxPython
But the same bad magic number error as before. No idea where there are conflicting .pyc files
Hi,
1 - install the requisites :
2 - then download " wxPython-4.0.6-cp37-cp37m-linux_x86_64.whl "
:
https://extras.wxpython.org/wxPython4/extras/linux/gtk3/fedora-28/
3 - finally go to the directory where you downloaded the file,
and try :
sudo pip3 install wxPython-4.0.6-cp37-cp37m-linux_x86_64.whl
Good luck,
It has worked for me on Fedora 30… if you have Fedora 29/28 :
choose the right WHL version of python (cp36 ?..)
Regards
Thanks for this.
I did as you suggested. The only difference that I installed for my user, i.e.
pip-3 install --user wxPython-4.0.6-cp37-cp37m-linux_x86_64.whl
But the same bad magic number error persists.
Are you sure that the python you are using to run the wx script matches the version the wheel was built for?
$ /usr/bin/python3 --version
Python 3.7.4
$ /usr/bin/python3 wx_test1.py
Traceback (most recent call last):
File "wx_test1.py", line 4, in <module>
import wx
ImportError: bad magic number in 'wx': b'\x03\xf3\r\n'

Did you try to clean up your system with deleting the wx directories in :
/usr/local/lib64/python3.7/site-packages
Before installing the wxPython-4.0.6-cp37-cp37m-linux_x86_64.whl ?

Can you try the command :
sudo pip3 install wxPython-4.0.6-cp37-cp37m-linux_x86_64.whl
?
I don’t have (and didn’t have) anything in /usr/local/lib64/python3.7/site-packages. I also checked
/usr/lib64/python3.7/site-packages/wx which didn’t exist.
I tried your suggestion no 2. and it was installed into /usr/local/lib64/python3.7/site-packages:
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.

But nevertheless, the bad magic number errror persists
Try :
[aaa@localhost ~]$ python3 Python 3.7.3 (default, May 11 2019, 00:38:04) [GCC 9.1.1 20190503 (Red Hat 9.1.1-1)] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import wx >>> print (wx.__version__) 4.0.6
I don’t reach the print statement as the import statement fails already.
The system where things fail is a Fedora 31 beta.
I tried things now on a Fedor 30 by installing the whl file and import wx works ok.
So, either there is a problem related to Fedora31 or there is another system specific problem
Ok, I found the cause of all. It was a beginner’s error on my side.
My first test was to name my test script wx.py. This caused an error because I am not allowed to use the same name as the installed wx module.
I renamed wx.py to wx_test1.py but forgot to delete wx.pyc. This caused the import error.
Sorry, that I was so stupid.
