ℹ️ Created by Codra/Pierre Raybaut in 2023, developed and maintained by DataLab open-source project team with the support of Codra.

ℹ️ DataLab is powered by PlotPyStack 🚀.

ℹ️ DataLab is built on Python and scientific libraries.

Overview

DataLab is a generic signal and image processing software based on Python scientific libraries (such as NumPy, SciPy or scikit-image) and Qt graphical user interfaces (thanks to the powerful PlotPyStack - mostly the guidata and PlotPy libraries).

DataLab is available as a stand-alone application (see for example our all-in-one Windows installer) or as an addon to your Python-Qt application thanks to advanced automation and embedding features.

✨ Add features to DataLab by writing your own plugin (see plugin examples) or macro (see macro examples)

✨ DataLab may be remotely controlled from a third-party application (such as Jupyter, Spyder or any IDE):

• Using the integrated remote control feature (this requires to install on your environment DataLab as a Python package and all its dependencies)

• Using the lightweight DataLab Simple Client (pip install cdlclient)

See home page and documentation for more details on the library and changelog for recent history of changes.

💡About DataLab Windows installers:

• DataLab Windows installer is available for Windows 8, 10 and 11 (main release, based on Python 3.11) and also for Windows 7 SP1 (Python 3.8 based release, see file ending with -Win7.exe).
• ⚠️ On Windows 7 SP1, before running DataLab (or any other Python 3 application), you must install Microsoft Update KB2533623 (Windows6.1-KB2533623-x64.msu) and also may need to install Microsoft Visual C++ 2015-2022 Redistribuable package.

New in DataLab 0.9

New key features in DataLab 0.9:

• New third-party plugin system to add your own features to DataLab
• New process isolation feature to run computations safely in a separate process
• New remote control features to interact with DataLab from Spyder, Jupyter or any IDE
• New remote control features to run computations with DataLab from a third-party application
• New data processing and visualization features (see details in changelog)
• Fully automated high-level processing features for internal testing purpose, as well as embedding DataLab in a third-party software
• Extensive test suite (unit tests and application tests) with >80% feature coverage

Installation

From the installer

DataLab is available as a stand-alone application, which does not require any Python distribution to be installed. Just run the installer and you're good to go!

The installer package is available in the Releases section.
