argospm [-h] {update,search,install,list,remove} [args]

argospm is the package management CLI for Argos Translate, an open-source offline translation library. It manages the download and installation of translation language packages (neural machine translation models) that enable offline text translation between language pairs.
Each package provides translation between a specific source and target language. Packages are downloaded from the Argos Translate package index and stored locally for use by the argos-translate Python library and LibreTranslate web interface.

update

Download the remote package index from the Argos Translate package repository.

Search for available translation packages in the remote index. Use --from-lang and --to-lang to filter by language pair.

Install a translation package by name (e.g., translate-en_es).

List all currently installed translation packages.

Remove an installed translation package by name.

Display help message and exit.

Translation packages can be large as they contain neural network models. The package index must be updated with argospm update before searching or installing new packages. Quality varies between language pairs — well-resourced language pairs like English-Spanish have better translation quality than less common pairs.

argospm is part of the Argos Translate project, an open-source neural machine translation library built in Python using OpenNMT. The project was created by Argos Open Technologies to provide free, offline translation capabilities as an alternative to cloud-based services. It also powers LibreTranslate, a self-hosted translation API.
