Python 为什么在尝试在Colab中导入pyatogui时会出现此错误？

这就是我在第一个牢房里看到的

然后，当我尝试导入pyautogui时，它显示以下错误：

!sudo apt install tesseract-ocr

!pip install pytesseract

!pip install pyinstaller

!pip install pyautogui

!pip install pillow

!pip install python3_xlib python-xlib

---

我想这与colab无法连接到我的计算机有关，但我不知道。

可能是因为X服务器没有运行。不确定是否可以在其中安装xorg。pyautogui在服务器窗口中执行操作对您来说是否干净？如果你想拥有一个笔记本，并在本地窗口上进行操作，你必须在你的机器上使用本地的jupyter笔记本。那么我必须使用jupyter笔记本？在colab中使用pyautogui是不可能的吗？即使你可以控制那边的窗口，远程机器。你想用pyautogui实现什么？我想截取一个由python程序解决的数独游戏的屏幕截图
