PostgresML is written in Rust, so you'll need to install the latest compiler from[rust-lang.org](https://rust-lang.org). Additionally, we use the Rust PostgreSQL extension framework`pgrx`, which requires some initialization steps:

cargo install cargo-pgrx --version 0.9.8&& \

cargo install cargo-pgrx --version 0.11.2&& \

cargo pgrx init

virtualenv pgml-venv&& \

source pgml-venv/bin/activate&& \

pip install -r requirements.txt&& \

pip install -r requirements-xformers.txt --no-dependencies

pip install -r requirements.txt

{% endtab %}

We like and use pgvector a lot, as documented in our blog posts and examples, to store and search embeddings. You can install pgvector from source pretty easily:

git clone --branch v0.4.4 https://github.com/pgvector/pgvector&& \

git clone --branch v0.5.0 https://github.com/pgvector/pgvector&& \

cd pgvector&& \

echo"trusted = true">> vector.control&& \

make&& \

cd pgml-extension&& \

cargo install cargo-pgrx --version 0.9.8&& \

cargo install cargo-pgrx --version 0.11.2&& \

cargo pgrx init
