在Ubuntu上启动Spyder时的错误22.04

Question

我刚刚升级了我的Ubuntu。我在Spyder上有一个错误：

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.main(options, args)

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

    plugin_client = Plugin(self.main)

    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'

我发现与特定应用程序交易的所有解决方案都开发了我的不同用户，而不是与升级或Ubuntu相关的概率。

Answer 1

作为一个快速解决方法，只需评论文件中的行：

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

Answer 2

（ spyder维护者在这里）Ubuntu 22.04提供的Spyder软件包（ 4.2.1 ，于2020年12月发布）与随附的Python版本（ 3.10 ）。

但是，该错误是在2022年3月发布的Spyder 5.3.0 中解决的。 我们的文档。

Answer 3

我遇到了完全相同的问题，对以下两个项目进行了搜索：

“ spyder” +“ mainwindow.py，line 3624”＃aka aka a parter ofer message

我在spyder的github上找到了错误报告＃16571：与Python 3.10“一起游览，将Python 3.10确定为罪魁祸首。

在Debian + Waptitude中，我将Python 3从3.10降至3.9版，再次推出了Spyder，并解决了问题！
