SMG Python Bindings
This directory contains the Python bindings for SMG (Shepherd Model Gateway), built using maturin and PyO3.
Quick Start
Installation
pip install maturin
cd smg/bindings/python
maturin develop --features vendored-openssl
Usage
The smg serve command launches backend workers and the SMG router in a single command:
# sglang with gRPC (default)
smg serve --backend sglang --model-path /path/to/model --port 8080
# sglang with HTTP
smg serve --backend sglang --model-path /path/to/model --port 8080 --connection-mode http
# vLLM (gRPC only)
smg serve --backend vllm --model /path/to/model --port 8080
# TensorRT-LLM (gRPC only)
smg serve --backend trtllm --model /path/to/model --port 8080
# Multiple workers (data parallel)
smg serve --backend sglang --model-path /path/to/model --port 8080 --dp-size 4
Serve Options
| Option | Default | Description |
|---|---|---|
--backend |
sglang |
Backend to use: sglang, vllm, or trtllm |
--connection-mode |
grpc |
Connection mode: grpc or http. vllm/trtllm only support grpc |
--host |
127.0.0.1 |
Host for the router |
--port |
8080 |
Port for the router |
--dp-size |
1 |
Data parallel size (number of worker replicas) |
--worker-host |
127.0.0.1 |
Host for worker processes |
--worker-base-port |
31000 |
Base port for workers |
--worker-startup-timeout |
300 |
Seconds to wait for workers to become healthy |
Backend-specific options (e.g., --tensor-parallel-size, --quantization) are passed through to the backend.
