Practical overview

When it fits

Use it when an equation is available as an image and LaTeX markup would help with editing or document preparation. Developers can use the repository when they want to investigate the data-preparation and training process.

Who it is for

  • People who want to transcribe photographed or scanned equations into editable LaTeX.
  • Developers exploring or adapting an image-to-markup model and its training workflow.

Documented uses

  • Convert an equation image into LaTeX markup.
  • Prepare the im2latex-100k dataset for model work.
  • Train a model and retrieve a checkpoint using the documented repository workflow.
Before you choose

Requirements & limits

The source code is publicly available under the MIT license.

  • The model’s reported test character error rate is 0.17; the README notes that visually equivalent LaTeX can still be counted as an error.
  • The README reports issues with some symbol styling and larger-than-training images.
  • The repository documents development setup and model training, but those instructions are separate from using the Streamlit interface.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Prepare the repository for development

Clone the project and install its development dependencies in a virtual environment.

Before you start

  • A command line and Git
  • Python environment support as required by the project setup

Steps

  1. Clone the repository with the command below.

    Documented command
    git clone https://github.com/kingyiusuen/image-to-latex.git

  2. Change into the project directory with cd image-to-latex.

  3. Create the virtual environment with the command below.

    Documented command
    make venv

  4. Install development dependencies with the command below.

    Documented command
    make install-dev

Expected outcome

The repository and its development dependencies are set up; the documented steps do not include running the app.

Guide limitations

  • This is a setup recipe, not instructions for launching the Streamlit app or converting an image.
