无法连接到任何 X 显示器：Google Colab 运行-time

Question

我现在正在处理一个分类问题，并尝试在线完成所有操作，而无需访问我的本地计算机。所以我已经将我的数据添加到驱动器并将我的驱动器安装在 Colab 上。现在我想注释我的数据并决定使用 LabelImg 注释器。我将 git 克隆到 Colab 并尝试按照步骤建议的方式启动它。但是我遇到了一个错误。尽管看了其他类似的答案，我还是无法解决问题

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（连同编译说明）：

从报错信息来看，是因为LabelImg使用了QT

QT 是一个 GUI 库，只能运行在您的本地计算机上。你不能运行它在云端，然后让它在你的机器上打开一个QTwindow。

您可能需要寻找另一个使用 web-interface 的标签库。
