白屏的话，大概率是没有前端文件。你是本地开发还是通过 pip 安装的？

我是通过pip安装的

[Y-ASLant]

使用uv创建的python虚拟环境，试了py3.10 3.12 3.13都是白屏状态

[gary-Shen]

我使用 uv 按下面步骤没有复现你说的现象：

uv venv --python 3.11

# 可选，报错 ModuleNotFoundError: No module named 'pkg_resources' 时需要安装
uv pip install setuptools
uv pip install labelu

uv run labelu

[gary-Shen]

浏览器控制台有什么报错吗？
