Computes multiple object tracker (MOT) evaluation metrics including MOTA, MOTP, and ID measures by matching ground truth objects to predictions across video frames.
Install it if you need to evaluate or compare object trackers; skip it if your use case does not involve multi-object tracking metrics.
Moto mocks AWS services for testing, allowing you to test code that calls boto3 without hitting real AWS infrastructure.
Install it if you write code that calls boto3.
Mocks AWS services for testing by intercepting boto3 calls, allowing you to test AWS-dependent code without hitting real AWS infrastructure.
Motor provides a non-blocking MongoDB driver for asyncio and Tornado applications, presenting a coroutine-based API for concurrent database access without blocking the event loop.
However, it is scheduled for deprecation on May 14th, 2026, with MongoDB strongly recommending migration to the PyMongo Async driver.
Provides Python type stubs for Motor, enabling static type-checking and IDE autocompletion for Motor's AsyncIO-based MongoDB driver without runtime overhead.
However, be aware the project is abandoned and may not track Motor API changes beyond version 3.0.0+.
MouseInfo displays the XY coordinates and RGB color of the pixel under your mouse cursor in a GUI window, useful for planning GUI automation scripts.
Provides Rust-accelerated parsing and filtering for MoviePilot, a media management application, with modules for RSS/Atom feeds, metadata extraction, and rule-based filtering.
However, verify the license terms first (currently unclear), and confirm that your platform has a compatible pre-built wheel available.
MoviePy is a Python library for video editing that reads, processes, and writes video and audio files by converting them to numpy arrays for frame-level manipulation and effect application.
Moyopy is a Python binding for Moyo, a crystal symmetry finder that identifies and analyzes symmetry operations in crystalline structures.
Parses SQL queries into JSON-serializable parse trees, and can generate SQL from JSON objects, supporting basic SELECT queries with clauses like WHERE, ORDER BY, and window functions.
However, install only if you do not require support for advanced SQL dialects or expect active maintenance; the latest release is from May 2021 and the project is…
Extracts and formats stack traces from minidump files generated by crashed processes, primarily for Firefox and Mozilla testing workflows.
However, the dormant maintenance status means you should verify that it works with your Python version and that the underlying stackwalk binary is available in your…
Provides utilities for launching and managing applications under native code debuggers, designed for Mozilla testing workflows.
However, the aging maintenance status suggests it is stable but not actively developed—verify that it meets your specific debugger and platform requirements before…
Manages and controls connected mobile devices and emulators for testing and automation purposes, with a single runtime dependency on mozlog for logging.
Provides file and directory utilities for Mozilla testing workflows, including operations like temporary file management, directory traversal, and file comparison.
Integrates Django applications with OpenID Connect identity providers to handle authentication and authorization through OIDC-enabled services.
However, maintenance is aging (238 days since last release); verify that Django 5.2 compatibility is current for your version before adopting.
Parses and processes Mozilla repository URLs, centralizing URL parsing logic for Mozilla projects.
However, it is aging (437 days since last release) and appears to be Mozilla-internal tooling; verify that it solves your specific URL-parsing need before adopting it.
Provides Mozilla-specific transforms and utilities for Taskgraph, extending the taskcluster-taskgraph library with Mozilla's build and release automation conventions.
Parse and validate Mozilla product version numbers, classify them as nightlies or releases, and compare versions for ordering.
Install it if you need to parse or validate Mozilla version numbers; skip it if you only work with standard semantic versioning.
Provides system information detection for Mozilla testing environments, identifying OS, architecture, and platform details needed by test automation.
No—not for new projects.
Extracts memory leaks from leak log files, primarily for Firefox and Mozilla testing workflows.
Provides structured logging for Python applications with specialized support for Mozilla testing and automation workflows, handling console output formatting and log aggregation.
Provides utilities for spawning, managing, and terminating processes with Mozilla-specific enhancements, wrapping platform-specific process handling logic.
Creates and modifies Mozilla application profiles—configuration directories that define browser settings, extensions, and runtime state for Firefox and other Mozilla applications.
Mozrunner manages the lifecycle of Mozilla applications (Firefox, Thunderbird, etc.) — starting, stopping, and configuring them programmatically for testing and automation.
Provides shell command-line parsing utilities for Mozilla testing infrastructure, handling argument processing and shell interactions.
However, be aware that maintenance is aging—expect no active development, and verify that it integrates with your specific workflow before adopting it.
Monitors system resource usage by wrapping psutil, primarily for Mozilla testing and automation workflows.
Extracts and reports version information from Firefox and other Mozilla applications on the local system.
A Python client for querying and downloading materials science data from the Materials Project database, providing programmatic access to computed properties and structures.
mpi4py provides Python bindings for the Message Passing Interface (MPI) standard, enabling distributed and parallel computing across multiple processes and machines.
Provides a high-performance Message Passing Interface (MPI) implementation for parallel computing applications, with support for multiple network modules and process management.
MPIRE provides a faster, more feature-rich alternative to Python's standard multiprocessing.Pool, with an API designed for easy parallelization of embarrassingly parallel tasks.
