前言

项目地址：这儿

一、安装

版本要求
Python: 3.7+
PyTorch: >=1.7.1

安装：

pip install torch torchvision torchaudio
1

pip install "pix2tex[gui]
1

注意：Pyside6 和 PyQt6 版本需要保持一致，否则会报 QT 错误

二、使用

打开 Windows 终端，输入命令：

latexocr
1

注意：需要将 latexocr.exe 所在路径添加到系统 Path 路径下，以便找到该可执行文件

例如：

三、

可以识别出来，如果识别有错误，可以直接在 gui 界面修改 Latex 代码，公式会实时更新，修改好之后再复制。

四、报错

因为下载模型文件时网络错误，导致模型文件下载不全

路径下：

删除未下载完的 .pth 文件，再次运行即可
