Synapse Plugin config.yaml Guide

The config.yaml file (or synapse.yaml) defines your plugin's metadata, actions, and runtime configuration.

Minimal Example

actions:
  train:
    entrypoint: plugin.train:TrainAction
    method: job
    description: "Train a model"

Complete Structure

Copy# Basic metadata
name: "YOLOv8 Object Detection"
code: yolov8
version: 1.0.0
category: neural_net
description: "Train and run YOLOv8 models"
readme: README.md

# Package management
package_manager: pip  # or 'uv'
package_manager_options: []
wheels_dir: wheels

# Environment variables

  DEBUG: "false"
  BATCH_SIZE: "32"

# Runtime environment (Ray)
runtime_env: {}

# Data type configuration
data_type: image
tasks:
  - image.object_detection
  - image.segmentation

# Actions
actions:
  train:
    entrypoint: plugin.train:TrainAction
    method: job
    description: "Train YOLO model"
  inference:
    entrypoint: plugin.inference:run
