model-archiver
Model Archiver is used for creating archives of trained neural net models that can be consumed by MXNet-Model-Server inference
Decision gist · record as of 2026-08-14
No. Although install friction is low and the license is permissive, the project is abandoned (archived repository, no releases since 2019, last commit 2024-05-20). MXNet-Model-Server itself is no longer actively maintained, and this tool is unlikely to work reliably with modern Python versions or current model-serving frameworks. Consider modern alternatives like TorchServe, TensorFlow Serving, or other actively maintained model-packaging tools.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- ONNX support requires manual installation of protobuf compiler, onnx, and mxnet; the tool itself does not declare these as dependencies.
- Install friction is low; the package is a pure-Python wheel with only two lightweight runtime dependencies (future and enum-compat).
- However, the repository is archived and the latest release dates to 2019-05-16, with no commits since 2024-05-20—this is an abandoned project with no active maintenance.

What it is and what it does
Model Archiver is a command-line tool that packages trained neural network models into `.mar` archive files suitable for inference with MXNet-Model-Server. It accepts a model file, a handler script, and metadata, then bundles them into a standardized archive format that MMS can consume and serve. The tool is lightweight, depending only on future and enum-compat for compatibility.
The package is part of the broader MXNet-Model-Server (MMS) ecosystem but can be installed standalone. It was designed to streamline the workflow of taking a trained model from development into a serving-ready format. However, the project is now archived with no active maintenance since mid-2024, and the latest release is from 2019, making it a legacy tool that may not align with current deep-learning deployment practices or MXNet versions.
Use it for
- Package a trained PyTorch or MXNet model into a `.mar` file for deployment with MXNet-Model-Server.
- Automate model archiving in a CI/CD pipeline to prepare models for inference serving.
- Bundle a model with a custom inference handler to define preprocessing and postprocessing logic.
- Create reproducible model archives for sharing trained models across teams or environments.
