Once computed, the matrix profile unlocks a range of time series analysis tasks: discovering repeated patterns (motifs), finding anomalies (discords), performing semantic segmentation, and extracting time series chains. The library is built on numpy, scipy, and numba; numba's JIT compilation provides the speed needed to handle large datasets efficiently. STUMPY offers multiple entry points: stump for single-dimensional data, mstump for multi-dimensional data, gpu_stump for GPU acceleration, and stumped/mstumped for distributed computation via Dask.\n\nThe package is designed for researchers, data scientists, and developers working with time series. It supports modern Python versions (3.10+) and runs on Linux, macOS, and Windows. The API is straightforward\u2014typically a single function call with a time series and a window size parameter\u2014and the library is actively maintained with comprehensive documentation and tutorials.","worth_installing":"Yes. STUMPY is actively maintained, has no known vulnerabilities, installs with low friction, and is licensed permissively. It fills a specific and well-defined niche in time series analysis. Install it if you need matrix profile computation or the downstream mining tasks it enables; skip it if your time series work is limited to forecasting or simple statistics."},"id":"stumpy","links":{"html":"https://skillfed.io/packages/stumpy","md":"https://skillfed.io/packages/stumpy.md","pypi":"https://pypi.org/project/stumpy/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-02-08","license_spdx":"BSD-3-Clause","license_treatment":"permissive","name":"stumpy","python_support":"supports_current","summary":"A powerful and scalable library that can be used for a variety of time series data mining tasks"},"popularity":{"monthly_downloads":476268,"position":6449,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.14.1"}
