构建

您可以使用 pig build 命令构建 pgml 扩展的 RPM / DEB 包：

BASH

pig build pkg pgml         # 构建 RPM / DEB 包

安装

您可以直接安装 pgml 扩展包的预置二进制包，首先确保 PGDG 和 PIGSTY 仓库已经添加并启用：

BASH

pig repo add pgsql -u          # 添加仓库并更新缓存

使用 pig 或者是 apt/yum/dnf 安装扩展：

安装

BASH

pig install pgml;          # 当前活跃 PG 版本安装

pig

BASH

pig ext install -y pgml -v 17  # PG 17
pig ext install -y pgml -v 16  # PG 16
pig ext install -y pgml -v 15  # PG 15
pig ext install -y pgml -v 14  # PG 14

dnf

BASH

dnf install -y pgml_17       # PG 17
dnf install -y pgml_16       # PG 16
dnf install -y pgml_15       # PG 15
dnf install -y pgml_14       # PG 14

apt

BASH

apt install -y postgresql-17-pgml   # PG 17
apt install -y postgresql-16-pgml   # PG 16
apt install -y postgresql-15-pgml   # PG 15
apt install -y postgresql-14-pgml   # PG 14

预加载配置：

BASH

shared_preload_libraries = 'pgml';

创建扩展：

SQL

CREATE EXTENSION pgml;

用法

该扩展缺乏维护

在所有集群节点上安装 pgml 扩展及 Python 依赖后，即可在 PostgreSQL 集群中启用 pgml。

使用 patronictl 修改集群配置，将 pgml 添加到 shared_preload_libraries 中，并在 pgml.venv 中指定 venv 目录：

YAML

shared_preload_libraries: pgml, timescaledb, pg_stat_statements, auto_explain
pgml.venv: '/data/pgml'

完成后，重启数据库集群，然后使用 SQL 命令创建扩展：

SQL

CREATE EXTENSION vector;        -- 建议同时安装 pgvector！
CREATE EXTENSION pgml;          -- 在当前数据库中创建 PostgresML
SELECT pgml.version();          -- 打印 PostgresML 版本信息

如果一切正常，应当看到类似如下的输出：

BASH

# create extension pgml;
INFO:  Python version: 3.11.2 (main, Oct  5 2023, 16:06:03) [GCC 8.5.0 20210514 (Red Hat 8.5.0-18)]
INFO:  Scikit-learn 1.3.0, XGBoost 2.0.0, LightGBM 4.1.0, NumPy 1.26.1
CREATE EXTENSION

# SELECT pgml.version(); -- 打印 PostgresML 版本信息
 version
---------
