Inference

The table below lists the build variants available as officially supported packages. Others can be built from source from each release branch.

Requirements

{: .no_toc }

• All builds require the English language package with en_US.UTF-8 locale. On Linux, install language-pack-en package by running locale-gen en_US.UTF-8 and update-locale LANG=en_US.UTF-8

• Windows builds require Visual C++ 2019 runtime.

• Please note additional requirements and dependencies in the table below:
