NumPy
The fundamental N-dimensional array library powering Python's scientific computing stack.
PyTorch
A Python-first tensor library with GPU acceleration and a dynamic, define-by-run autograd engine for building and training deep neural networks.
Datasets
One-line loading and fast, Arrow-backed processing for thousands of ML datasets
orjson
A fast, correct, Rust-backed JSON library for Python with native dataclass, datetime, and numpy support
einops
A readable, framework-independent notation for tensor rearrangement, reduction, and repetition.
schema-dts
TypeScript type definitions for Schema.org's JSON-LD vocabulary, giving structured data literals full autocomplete and compile-time validation.
ormsgpack

TensorFlow Datasets
Ready-to-use, versioned public datasets exposed as tf.data.Dataset objects, with first-class support for TensorFlow, JAX, and NumPy pipelines.
SimSIMD
SIMD-accelerated distance, dot-product, and similarity kernels for high-dimensional vectors.
Ladybug
Native Node.js bindings for Ladybug, an embeddable Cypher graph database with zero-copy Arrow results.
rust-numpy
PyO3-based Rust bindings to the NumPy C-API for sharing array data between Rust and Python.
tifffile
A comprehensive Python library for reading and writing TIFF, BigTIFF, OME-TIFF, and dozens of proprietary microscopy image formats as NumPy or Zarr arrays.
DataComPy
Compare Pandas, Polars, Spark, and Snowpark DataFrames with human-readable difference reports.
cython-blis
Fast BLAS-style matrix multiplication for Python, bundled as a self-contained C extension with no system BLAS dependency.
Graft
A CLI that builds a persistent, readable context graph of your codebase so coding agents stop re-exploring it from scratch every session.
