我现在正在研究分类问题，并尝试在线完成所有工作，而无需访问本地计算机。
因此，我已将数据添加到驱动器并将驱动器安装在 Colab 上。现在我想注释我的数据并决定使用LabelImg https://github.com/tzutalin/labelImg注释者。我将 git 克隆到 Colab 并尝试按照步骤建议的方式启动它。但我遇到了一个错误。
尽管查看了其他类似的答案，但我无法解决问题
要克隆和启动的代码：
import os
os.chdir('/content')
!git clone 'https://github.com/tzutalin/labelImg.git'
os.chdir('/content/labelImg')
!sudo apt-get install pyqt5-dev-tools
!sudo pip3 install -r requirements/requirements-linux-python3.txt
!make qt5py3
!python3 labelImg.py
!python3 labelImg.py ['/content/labelImg'] []
错误（以及编译说明）：
Reading package lists... Done

Reading state information... Done
pyqt5-dev-tools is already the newest version (5.10.1+dfsg-1ubuntu2).
The following package was automatically installed and is no longer required:
libnvidia-common-410
Use 'sudo apt autoremove' to remove it.

从错误信息来看，是因为LabelImg使用了QT。
QT 是一个只能在本地计算机上运行的 GUI 库。你不能在云端运行它，然后让它在你的机器上打开一个QT窗口。
您可能需要找到另一个使用网络界面的标签库。
