我刚刚升级了我的ubuntu。我在spyder上遇到这个错误：

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')())
  File "/usr/lib/python3/dist-packages/spyder/app/start.py", line 213, in main
    mainwindow.main(options, args)
  File "/usr/lib/python3/dist-packages/spyder/app/mainwindow.py", line 3624, in main
    mainwindow = create_window(app, splash, options, args)
  File "/usr/lib/python3/dist-packages/spyder/app/mainwindow.py", line 3482, in create_window
    main.setup()
  File "/usr/lib/python3/dist-packages/spyder/app/mainwindow.py", line 803, in setup
    self.completions = CompletionManager(self)
  File "/usr/lib/python3/dist-packages/spyder/plugins/completion/plugin.py", line 97, in __init__
    plugin_client = Plugin(self.main)
  File "/usr/lib/python3/dist-packages/spyder/plugins/completion/kite/plugin.py", line 50, in __init__
    self.installer = …

我有以下数据框：

A,B,C,D   
10,1,2,3
 1,4,7,3
10,5,2,3
40,7,9,3
9,9,9,9

我想从前一个只有两行的数据帧开始创建另一个数据帧。这两行的选择基于“A”列中的最小值和最大值。我想得到：

A,B,C,D   
 1,4,7,3
40,7,9,3

你认为我应该使用一种 index.min e index.max 然后只选择两行然后附加到一个新的数据帧中吗？你有同样的其他建议吗？

感谢您的任何帮助，最好
