Pyside "module not found"

Are you sure that you are pointed to the same interpreter in PyCharm that you used to install PySide? Take a look at Preferences -> Python Interpreter and see if pyside shows up in the installed packages.

Hi! Currently i have the same problem. I downloaded the CE and the pro version. It only works with the pro version of the 2017. The ce doesnt autocomplete or runs pyside. Is there ant restriction for the CE regarding this?

Hi Alenrqz21! There should be no difference between PE and CE, are you sure both use the same interpreter? Could you please specify what error do you receive in CE after run? Feel free to create a ticket in our bug tracker.

The same error happens. It says QtCore module not found. It is strange because it works perfect with the Pro. Also autocompeltation works fine in Pro with PySide. Only the CE have this issue.

Alenrqz21, do you use Anaconda interpreter?

Same EXACT problem.

PyCharm 2021.2.3 (CE)

Build #PC212.5457.59, built on October 19, 2021

File -> Settings -> Project: main.py -> Python Interpreter:

PySide2 5.15.2

qt.widgets 0.18 (in case it matters)

my code(gui.py):

from PySide2.QtWidgets import QApplication, QMainWindow
import pyqtgraph as pg
import sys


class MainWindow(QMainWindow):

    def __init__(self):
        super(MainWindow, self).__init__()

        self.graphWidget = pg.PlotWidget()
        self.setCentralWidget(self.graphWidget)

        hour = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
        temperature = [30, 32, 34, 32, 33, 31, 29, 32, 35, 45]

        # plot data: x, y values
        self.graphWidget.plot(hour, temperature)


def run():
    app = QApplication(sys.argv)
    w = MainWindow()
    w.show()
    app.exec_()

main.py:

import gui.py

gui.run()

Terminal (in PyCharm):

python main.py

PS F:\my_file> python main.py
Traceback (most recent call last):
File "main.py", line 9, in <module>

Hello, 

could you please run the code out of PyCharm with the same interpreter? Will you get the same error? 

For more information on how to run your code from the terminal outside of IDE, please see the following article:
https://docs.python.org/3/using/cmdline.html#command-line

If you're using virtualenv interpreter in PyCharm, you may need to activate it in the command line prior to running your code:
https://virtualenv.pypa.io/en/latest/user_guide.html#activators

Yes, same error from the command line.

I'm not using virtualenv interpreter.

All my other python code works fine. It's just PySide.

From CMD:

F:\>cd my_directory\

F:\my_directory>python main.py
Traceback (most recent call last):
File "main.py", line 9, in <module>
import gui
File "F:\my_directory\gui.py", line 1, in <module>
from PySide2.QtWidgets import QApplication, QMainWindow
ImportError: No module named PySide2.QtWidgets

F:\my_directory>

I then realized my Python version in PATH was 2.7, so I changed it to 3.7.8

C:\Users\me>python --version
Python 3.7.8

C:\Users\me>f:

F:\>cd my_directory

F:\my_directory>python main.py

At this point I multi-line commented the deprecated code in main.py, which was simply being used to report the process time.

This resulted in the code running fine in cmd.

Then I tried it again in PyCharm and it also worked fine.

# THE FIX

So, the problem was resolved by

• ensuring python37 was ahead of python27 in path
• removing some deprecated code from main.py
