I have just upgrade my ubuntu. I have this error on spyder:

Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
Traceback (most recent call last):
  File "/usr/bin/spyder", line 33, in <module>
    sys.exit(load_entry_point('spyder==4.2.1', 'gui_scripts', 'spyder')())

    mainwindow = create_window(app, splash, options, args)

    self._integration_widget = KiteIntegrationInfo(self)
  File "/usr/lib/python3/dist-packages/spyder/plugins/completion/kite/widgets/install.py", line 58, in __init__
    image = image.scaled(image_width, image_height, Qt.KeepAspectRatio,
TypeError: arguments did not match any overloaded call:
  scaled(self, int, int, aspectRatioMode: Qt.AspectRatioMode = Qt.IgnoreAspectRatio, transformMode: Qt.TransformationMode = Qt.FastTransformation): argument 1 has unexpected type 'float'
  scaled(self, QSize, aspectRatioMode: Qt.AspectRatioMode = Qt.IgnoreAspectRatio, transformMode: Qt.TransformationMode = Qt.FastTransformation): argument 1 has unexpected type 'float'

All the solution that I have found deal with specific application developed my different user and not for probel related to upgrade or ubuntu.

As a quick workaround just comment out the lines in File:

/usr/lib/python3/dist-packages/spyder/plugins/completion/kite/widgets/install.py

58

#image = image.scaled(image_width, image_height, Qt.KeepAspectRatio, Qt.SmoothTransformation)

143

#install_gif.setScaledSize(QSize(image_width, image_height))

244-247

#copilot_label.setPixmap(
            #    copilot_image.scaled(image_width, image_height,
            #                         Qt.KeepAspectRatio,
            #                         Qt.SmoothTransformation))

  • In my case, I just commented all the cases where I received an error in install.py, which were not exactly these lines...After this, it worked – D.MerBet Oct 07 '22 at 10:34

(Spyder maintainer here) The Spyder package provided by Ubuntu 22.04 (4.2.1, released in December 2020) is broken with the Python version that comes with it (3.10).

However, this error was fixed in Spyder 5.3.0, released in March 2022. So, to solve this problem please uninstall the Spyder that comes with Ubuntu and install it with pip in a virtualenv, as explained in our documentation.

I had the exact same problem, did a search with the following two items :

"spyder" + "mainwindow.py, line 3624" # aka a piece of the error message

I found the bug report #16571 on spyder's github : "TypeError in Tour with Python 3.10", which identified python 3.10 as the culprit.

In Debian + aptitude I downgraded python 3 from 3.10 to the 3.9 version, launched Spyder again and...problem solved !
