rapid_latex_ocr is a tool to convert formula images to latex format.
The reasoning code in the repo is modified from LaTeX-OCR, the model has all been converted to ONNX format, and the reasoning code has been simplified, Inference is faster and easier to deploy.
The repo only has codes based on ONNXRuntime or OpenVINO inference in onnx format, and does not contain training model codes. If you want to train your own model, please move to LaTeX-OCR.
If it helps you, please give a little star ⭐ or sponsor a cup of coffee (click the link in Sponsor at the top of the page)

Note
When installing the package through pip, the model file will be automatically downloaded and placed under models in the installation directory.
If the Internet speed is slow, you can download it separately through Google Drive or Baidu NetDisk.
pip install rapid_latex_ocrfrom rapid_latex_ocr import LatexOCR
model = LatexOCR()
img_path = "tests/test_files/6.png"
with open(img_path, "rb") as f:
data = f.read()
res, elapse = model(data)
print(res)
print(elapse)$ rapid_latex_ocr tests/test_files/6.png
