Python strong typing suite, along with Typed NumPy: Static shape typing and runtime shape validation.

[!WARNING] Experimental & WIP. See USAGE.md for more details.

Installation

Install uv (optional, recommended)

Install uv, if not already. Check here for installation instructions.

It is recommended to use uv, as it will automatically install the dependencies in a virtual environment. If you don't want to use uv, skip to the next step.

TL;DR: Just run

curl -LsSf https://astral.sh/uv/install.sh | sh

Install the package

The dependencies are listed in the pyproject.toml file. At present, the only required dependency is numpy.

Install the package from the PyPI release:

# Using uv
uv add typingkit

# Or with pip
pip3 install typingkit

To install from the latest commit:

uv add git+https://github.com/AshrithSagar/typingkit.git@main

Usage

from typing import TypeVar

from typingkit._typed.ndarray import TypedNDArray

# Shape variables are just regular TypeVar's
N = TypeVar("N", bound=int, default=int)
M = TypeVar("M", bound=int, default=int)

# Create aliases such as these, or use TypedNDArray directly
Vector = TypedNDArray[tuple[N]]
Matrix = TypedNDArray[tuple[M, N]]

v1 = Vector([1, 2, 3])  # Passes
v2 = Vector([4, 5, 6, 7])  # Also passes

v3 = TypedNDArray[tuple[int]]([[8, 9]])
# Fails, since expected 1D array but passed in a 2D array
