Question

我现在正在处理分类问题，并尝试在线进行所有操作，而不必访问我的本地计算机。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，我要注释数据，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。但是我被打错了。尽管查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（以及编译说明）：

Answer 1

从错误消息中，这是因为LabelImg使用QT。

QT是一个GUI库，只能在您的本地计算机上运行。您不能在云中运行它，然后让它在计算机上打开QT窗口。

您可能需要找到另一个使用Web界面的标签库。
