tesseract-python - Tesseract binary as a Python module

PyPI - Python Version PyPI

Current Scope

This module works on a range of configurations, but the PyPi package is more limited at this time.

Platforms Python 2.7 Python 3.6
Linux x86_64 PyPi Source
MacOS 10.13 PyPi
Windows

Legend

  • PyPi: Available on PyPi.
  • Source: Working with setup from source.
  • Empty: Planned for some future release.
  • No line/column: No plan to date.

Configuration

  • Tesseract 3.05.01
  • Leptonica 1.74.4
  • Pytesseract 0.2.0

Setup

The module setup relies on building Leptonica, then Tesseract, and finally producing a bdist_wheel. The procedure is automated with make.

git clone https://github.com/ic/tesseract-python.git
cd tesseract-python
make wheel

The procedure takes quite some time to complete. The wheel is availble under dist.

Note on package managers

The build scripts rely on the following defaults:

  • Apt on the Debian family, Yum on the Redhat family.
  • On MacOS, the script tries first MacPorts, then Homebrew.

Important: All managers have been tested, except Homebrew. If a Homebrew-based fails, please compare with the MacPorts version under scripts/{leptonica,tesseract}/dep_darwin.sh (a package may simply be missing or misnamed), and please consider a PR.

Roadmap

  • Hopefully manage to get the autoamated PyPi release process nailed and working fully.
  • Replace the current ugly shelling to the tesseract binary by proper calls to libtess. Inspiration in tesserocr.
