I've been switching a project from python2.7 to python3. All was good in pyhton2.7. I am using PySide and I have installed it on Ubuntu. The package exists and all the .so files are there but I get this error in python3
>>> import PySide
>>> from PySide import *
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: /usr/local/lib/python3.2/dist-packages/PySide/QtCore.so: undefined symbol: _ZN8Shiboken6Object4hashEP7_object
>>>
Any ideas how to resolve it?
I was using pip to install PySide but using
sudo apt-get install python3-pyside
did the trick

I'm trying to turn my python project into .exe
I used : pyinstaller --onefile main.py
Then I moved the main.exe into the original file to be sure it can access all the dependencies.
When I run the main.exe, I get an error, failed to execute script main.
I typed cmd in the directory of the python project, and tried python main.py
It gave me this error :
Traceback (most recent call last):
File "main.py", line 3, in <module>
from PyQt5 import QtWidgets, QtCore
ModuleNotFoundError: No module named 'PyQt5'
Even though every module are installed, why is it telling me that?
Thank you.
You haven't installed pyqt5.
Try pip install pyqt5 or pip3 install pyqt5
for linux
sudo apt install python3-pyqt5

import pdfkit
Error: Traceback (most recent call last):
File "<stdin>", line 1, in <module> ImportError: No module named 'pdfkit'
when i use pdfkit in python2 then it works fine, but if i use in python3 it gives the above error
Packages for Python 2 and Python 3 are completely separate. You have to install any package for both Python versions separately. Try:
sudo python3 -m pip install pdfkit
In an AWS EC2 instance, with Amazon Linux AMI 2016.09 distribution, I have installed numpy, inside my virtualenv where python 3.4 is the default version, with:
pip install numpy
It installs package numpy-1.12.1-cp34-cp34m-manylinux1_x86_64.whl without errors.
After that, in python I try to import it:
>>> import numpy
And I get:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'numpy'
Moreover, if I run pip freeze, numpy does not appear in the list.
Why is numpy not being found? and How to fix it?
Did you do this:
#:source .venv/bin/activate
.....
#:python
....
>>>pip3 install numpy
....
This works!
