AttributeError: Module 'PyQt5' has no attribute '__version__'

Question

I was trying to warp a python file to an .exe file. But with these two lines, I encountered this problem.

import cv2
exit()

Traceback (most recent call last):

AttributeError: Module 'PyQt5' has no attribute '__version__'

If I just print something like: print('dsfdsfs'), then it can be wrapped to an .exe successfully.

My environment:
win10
pyinstaller 5.0.dev0
opencv-python 4.5.2.54
pyqt 5.9.2

And I was using anaconda prompt to do so.

Answer 1

I'm using pyinstaller and anaconda prompt and found the same issue, to solve it you must

pip install PyQt5 --user --use-feature=2020-resolver

and then run pyinstaller again.

Answer 2

Try using "pip install PyQt5" and then run again

Answer 3

I solved this problem by manually adding __version__ = "5.15.4" to venv/Lib/site-packages/PyQt5/__init__.py where venv is a virtual environment in which PyQt5 is installed.

Before:

...
#

# WARRANTY OF DESIGN, MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.


# Support PyQt5 sub-packages that have been created by setuptools.
__path__ = __import__('pkgutil').extend_path(__path__, __name__)

def find_qt():
...

After:

...
# 
# This file is provided AS IS with NO WARRANTY OF ANY KIND, INCLUDING THE
# WARRANTY OF DESIGN, MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.


# Support PyQt5 sub-packages that have been created by setuptools.
__path__ = __import__('pkgutil').extend_path(__path__, __name__)
__version__ = "5.15.4"

def find_qt():
...

Answer 4

After loosing too many hours on this I updated PyInstaller and voilà it worked.

Answer 5

Unfortunately it seems that PyQt5 module on Anaconda is busted and missing various files that might be required by other modules, in my case PySimpleGui. The absolute easiest solution is to create a brand new environment, fortunately this is quite easy in anaconda, and pip install pyqt5. This should resolve any issues. Also install the rest of your packages and you should be good to go!
