{"id":5918,"library":"eckitlib","title":"eckitlib","description":"EcKit is a robust, cross-platform C++ toolkit developed by ECMWF, providing an abstraction layer for operating system features like multi-threading, JSON/YAML parsing, object serialization, file-system abstraction, and linear algebra. The `eckitlib` Python package serves as Python bindings for this core C++ toolkit, acting as a foundational component for higher-level scientific computing libraries within the ECMWF 'earthkit' ecosystem. It is actively maintained with frequent updates.","status":"active","version":"2.0.7.19","language":"en","source_language":"en","source_url":"https://github.com/ecmwf/eckit","tags":["scientific computing","data processing","ECMWF","C++ bindings","toolkit","meteorology","numerical weather prediction"],"install":[{"cmd":"pip install eckitlib","lang":"bash","label":"Install latest version"}],"dependencies":[{"reason":"eckitlib is the Python binding for the underlying C++ EcKit toolkit, which it bundles.
