Labelimg: PyQt4 and PyQt5 Error running labelImg

[gustavz]

I am working with python 2.7 so i wanted to use PyQt4. But when i follow the guide
sudo apt-get install pyqt4-dev-tools
sudo pip install lxml
make qt4py2
python labelImg.py

it gives me following error:
$ python labelImg.py Traceback (most recent call last): File "labelImg.py", line 27, in <module> import resources File "/home/gustav/DataSet/labelImg/resources.py", line 9, in <module> from PyQt4 import QtCore RuntimeError: the PyQt4.QtCore and PyQt5.QtCore modules both wrap the QObject class

although i do not have PyQt5 installed, only PyQt4.
(The same happens if i install globaly with pip (or pip2))

But however if i follow the same steps for python 3 and PyQt5 it works perfectly fine.

The thing is, i really would prefer to use the py2.7.

Any suggestions how to solve this?

• OS: Ubuntu 16.04
• PyQt version: PyQt4 and PyQt5

I met this issue too .when I uninstall pyqt4 and use pyqt5 instead,I solve the problem!

[harryprince]

same issue +1.

if I use pyqt5:

ImportError: No module named PyQt4.QtGui

If you are using pyqt5, you should call 'make qt4py2' or 'makr qt5py2'

[mesargent]

I had both pyqt5 and pyqt4 installed and got the same problem. When I uninstalled pyqt5 it worked.

[maverik-akagami]

"make qt4py2" worked for me

[ailuropoda0]

If there is an error for calling 'make qt4py2' or 'make qt5py2',
do 'make qt4' or 'make qt5' first.

I edited libs/ustr.py:

1. comment this line:#from PyQt4.QtCore import QString
2. change this:if type(x) == QString
   to this:if type(x) ==type('string')
   and it works

Worked for me, thanks!
First, i uninstalled qt4, installed qt5, then make qt5py3, then applied your solution (don't forget ' : ')
