Install it if you work with ROS data and need portable, lightweight bag file access.
Solves linear assignment problems using Jonker-Volgenant and related algorithms, supporting single and batch operations on square and rectangular cost matrices.
Install it if you need to solve assignment problems and want more flexibility or batch processing capabilities.
KeyBERT extracts keywords and keyphrases from documents by computing BERT embeddings and finding n-grams most similar to the document as a whole using cosine similarity.
Implements BATS and TBATS exponential smoothing methods for forecasting time series with complex seasonal patterns, built on numpy, scipy, scikit-learn, and pmdarima.
However, the last release was 2023-04-17 with no active maintenance.
Tests whether a graph is planar, computes planar embeddings, draws planar graphs as ASCII art, and isolates forbidden subgraphs using algorithms from the Edge Addition Planarity Suite.
CadQuery is a Python library for writing scripts that generate parametric 3D CAD models, outputting to formats like STEP, STL, DXF, VRML, AMF, and 3MF.
Chinese word segmentation for spaCy with domain-specific models (news, web, medicine, tourism) and optional part-of-speech tagging.
imutils provides convenience wrappers around OpenCV image processing operations—translation, rotation, resizing, skeletonization, edge detection, and Matplotlib display—to reduce boilerplate code.
No—install only if you are maintaining legacy code that already depends on imutils.
Converts between different 3D geometric transformations—rotation matrices, Euler angles, quaternions, and affine matrices—and composes or decomposes them.
Not recommended if you require active bug fixes or feature development.
IfcOpenShell is a Python library for parsing, manipulating, and working with Industry Foundation Classes (IFC) building information models across multiple IFC schema versions.
MXNet is a deep learning framework that enables you to build and train neural networks with support for multiple programming interfaces and hardware accelerators.
No, not for new projects.
Vector provides 2D, 3D, and 4D space-time vector operations optimized for working with arrays of vectors rather than individual vectors in loops, with support for multiple coordinate systems and data backends.
Install it if you need to work with spatial vectors at scale or in high-energy physics contexts.
