I'm trying to use PySide so I did a brew install pyside pyside-tools. However, I get the following error:
>>> from PySide.QtGui import QApplication
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: dlopen(/Library/Python/2.7/site-packages/PySide/QtGui.so, 2): Library not loaded: QtGui.framework/Versions/4/QtGui
Referenced from: /Library/Python/2.7/site-packages/PySide/QtGui.so
Reason: image not found
This SO question says to install python 27 and then reinstall pyside but I'm using the native python on mac osx 10.8 and it is already 2.7.2.
The Homebrew recipe for PySide seems to indicate that this should have been fixed but I'm still getting the errors. I made sure libpng is installed as well.
Looking at the path, I know that the QtGui.so file is there. Since I'm new to Python, PySide, and Qt, it is hard for me to Google and further troubleshoot.
If anyone knows why and can provide directions, I will be very grateful. It can involve uninstalling a bunch of stuff and reinstalling. Please give detailed instructions. I did uninstall and try to reinstall and got the same result.
Thank you.
I was getting the same error, and I'm using Python installed via Homebrew. I found two PySide libraries in /Library/Python/2.7/site-packages/ . Moving them out of the way, and re-building/installing PySide through Homebrew worked.
I tried the import you gave - I am using same system environment. It worked fine. try: brew update and re-install.
Got the same error when running ipython qtconsole which will import PySide to provide a Qt console.
Finally I thought there might be something wrong after PySide's installation. So I run pyside_postinstall.py -install manually which should be automatically run after PySide is installed, and this fixed my problem. Hopes working for your too!

Currently using Ubuntu 20.04 LTS with python3.8.5.
Its my first time using ubuntu with absolutely no previous knowledge of terminal.SO,would love to have a detailed answer if possible.
Below is terminal output when i try importing tkinter in python3.
>>> import tkinter
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python3.8/tkinter/__init__.py", line 36, in <module>
import _tkinter # If this fails your Python may not be configured for Tk
ModuleNotFoundError: No module named '_tkinter'
>>>
I have reinstalled python3 and tkinter using sudo apt.But still it shows same error.
When i run the same command in python IDLE it works without any error.
I hope this explains my problem clearly, if any other info. is required pls reply.
I also tried running the command >>>from tkinter import *
I faced the same issue on MacOS. I was using a Python virtual environment. This command worked for me:
brew install python-tk
CentOS 8 + Python 3.9.5
following are what i have doneļ¼
1st:
yum search tkinter
yum install python39-tkinter.x86_64
2nd:
yum install tk-devel
3rd: cd python3.9.5 source folder
make install
it work in my case
since I'm still using python 3.9, this code works for me:
brew install python-tk#3.9
if using brew install python-tk brew will install python-tk#3.10 which is key-only
I had the same issue. Switched from 3.8 to 3.7 and it worked. I'm using PyCharm CE, which makes it easy to switch between interpreters.
Resolved the issue it occurred because the Tkinter was installed for version 3.5 and not for the 3.8 version. For that, I installed the 3.5 version and kept only one version i.e. 3.8, and installed Tkinter again, and it worked!
This is just a workaround to make things work, but the more preferred way is to create a venv and then install the particular versions of python and libraries that are needed.
When I import tinker in python 3.7.3 on Ubuntu 18.04:
>>> import tkinter
I got:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python3.7/tkinter/__init__.py", line 36, in <module>
import _tkinter # If this fails your Python may not be configured for Tk
ModuleNotFoundError: No module named '_tkinter'
Then I install tk using both of the following:
sudo apt-get install python3-tk
It didn't work.
I also did all the things in Tkinter module not found on Ubuntu, still didn't work.
I noticed that when I do:
sudo apt-get install python3.7-tk
It says:
Note, selecting 'python3-tk' instead of 'python3.7-tk'
python3-tk is already the newest version (3.6.9-1~18.04).
Is tk automatically installed under python 3.6.9? How can I fix this?
I also saw a solution from https://wiki.python.org/moin/TkInter:
If it fails with "No module named _tkinter", your Python configuration needs to be modified to include this module (which is an extension module implemented in C). Do not edit Modules/Setup (it is out of date). You may have to install Tcl and Tk (when using RPM, install the -devel RPMs as well) and/or edit the setup.py script to point to the right locations where Tcl/Tk is installed. If you install Tcl/Tk in the default locations, simply rerunning "make" should build the _tkinter extension.
Could someone explain to do how to do the steps mentioned in this paragraph?
OK. I think the problem is that the newest version of tkinter for Ubuntu 18.04 is "python3-tk_3.6.9-1~18.04_i386.deb". Now I found that tk for python3.7.3 is available for other systems(e.g. python3-tk_3.7.3-1_amd64.deb). Can I download and use these ones on my system?
acw1668: Thanks this helped me a lot. I'm using Python 3.8. Using your method was able find where tkinter for Python 3.8 was install (/usr/lib/python3.8/). So i copied the files to (/usr/local/lib/python3.8/) which is where Python is installed on my computer. Now it'e working.
I am facing a situation where modules like pyodbc which used to work earlier (3 weeks back) are not working anymore in my laptop. I am repeatedly getting Module not found error.
To resolve it by myself, I have gone through similar articles in stack overflow and implemented some suggestions like this. Yet the issue still persists. My machine (Windows 10) has only one python version (python v3.7.2), and I have never created any virtualenv.
C:\Users\Kris\eclipse-workspace\SQLPyODBC>conntest.py --serverName "IDEA-PC\SQLEXPRESS" --name "SampleStore" --trustedConn "yes"
Traceback (most recent call last):
File "C:\Users\Kris\eclipse-workspace\SQLPyODBC\conntest.py", line 1, in <module>
import pyodbc
ModuleNotFoundError: No module named 'pyodbc'
The referenced package is available under C:\Users\Kris\AppData\Local\Programs\Python\Python37-32\Lib\site-packages directory. Also the path of python interpreter in eclipse IDE (PyDev) is pointing to correct python executable path.
Just to test, I have downloaded pymssql module, and guess what... it is also showing the same error message. I have uninstalled and re-installed packages. No solution.
If you're using Anaconda install using following code,
conda install -c anaconda pyodbc
Before importing pyodbc in python, you should install the module by using pip directly from cmd.
pip install pyodbc
if that does not work, try using pip to uninstall and install it again after a restart (Or kill all python related tasks). Hope it works
After upgrading to python-pyqt5 5.12-2 I get this error when I try to import from QtWidgets
from PyQt5.QtWidgets import *
Error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'PyQt5.sip'
Any idea on how can I solve this issue?
The reason is a backward incompatible change in PyQt-5.11
In geoptics this fix works on old and new versions:
try:
# new location for sip
# https://www.riverbankcomputing.com/static/Docs/PyQt5/incompatibilities.html#pyqt-v5-11
from PyQt5 import sip
except ImportError:
import sip
As suggested here pyuic5 - ModuleNotFoundError: No module named PyQt5.sip
Try uninstalling and re-installing all PyQt related libraries:
pip uninstall PyQt5
pip uninstall PyQt5-sip
pip uninstall PyQtWebEngine
Then install them again, this will fix:
ModuleNotFoundError: No module named 'PyQt5.sip'
ModuleNotFoundError: No module named 'PyQt5.QtWebEngineWidgets'
PPS.:If you got problems uninstalling the libraries, go to your Python folder, like C:\Users\<USERNAME>\AppData\Local\Programs\Python\Python<PYTHON-VERSION>\Lib\site-packages and manually delete the PyQt folders, them uninstall everything and install again (Make sure you have the latest Python version and upgraded your pip too)
If you're building sip and PyQt5 from source using make files, make sure to check PyQt5 install docs. In particular,
Note
When building PyQt5 v5.11 or later you must configure SIP to create a
private copy of the sip module using a command line similar to the
following:
python configure.py --sip-module PyQt5.sip
If you already have SIP installed and you just want to build and
install the private copy of the module then add the --no-tools option.
You should add PyQt5.sip to hidden imports; that should solve the issue.
I repaired this problem
This problem occurred when upgrading pyqt5 version 5.15.0
There was no problem when I reverted to the previous version.
I have
python -V: 3.7.4
PYQT5 5.14.1 and PYSIDE 5.14.1 works fine
In addition to the answer provided by Tadeu (https://stackoverflow.com/a/58880976/12455023) I would also suggest checking version of your libraries to make sure that they match.
Use pip show <library_name>
This will help you to make sure that no earlier installation is conflicting with your current installation.
In place of library_name use PyQt5, PyQt5-sip, PyQtWebEngine. If any of them is present in the system, then use pip uninstall <library_name>==<version_number> to remove that library.
Once you made sure that no other versions of these libraries are there, then you can reinstall the preferred version of that library.
I've followed the instructions on:
http://danmarner.com/2014/04/23/Installing-PyQt5-with-Python-3-On-OS-X.html
to first install SIP according to the instructions found at:
http://pyqt.sourceforge.net/Docs/sip4/installation.html
and then PyQt5 by following the instructions found here:
http://pyqt.sourceforge.net/Docs/PyQt5/installation.html
and then brew install qt5
but when I run the first example PyQt-gpl-5.3.2/examples/tutorials/addressbook/part1.py it fails with the following:
Traceback (most recent call last):
File "examples/tutorials/addressbook/part1.py", line 45, in <module>
from PyQt5.QtCore import Qt
ImportError: No module named PyQt5.QtCore
I'm running Mavericks 10.9.5 and Python 2.7.5
It doesn't seem like it's installed correctly, or if it is python can't find it. I'm not sure how to proceed so any suggestions are much appreciated!
The issue was resolved by adding /usr/local/lib/python2.7/site-packages to PYTHONPATH. Thanks to the comments found here:
https://stackoverflow.com/a/13103438/1729686
and to #Kash and #qqvc for the suggestions!
if you used brew, you can add into .bashrc
export PYTHONPATH=$(brew --prefix)/lib/python3.6/site-packages:$PYTHONPATH
(edit python3.6 to your python version).
And next, reload bash and run
echo $PYTHONPATH
if response not null, thats ok
