Before you choose
Requirements & limits
The repository is publicly accessible and the source code is distributed under the Apache-2.0 license. Python 3.10 through 3.14 is identified as supported in the project README.
- Python is the required implementation language identified by the project.
- The documented resource combines library modules with datasets and tutorials rather than being a standalone hosted application.
- Windows, Linux and macOS are listed as supported platforms.
- Corpus licensing can vary by dataset, so the README for each corpus governs its terms.
