This release is a pre-release and may not be stable for production use.
Manta SDK
Beta. The SDK is in beta and every published release is a pre-release (
pip install "mantatech-sdk>=0.6b5.dev0"). New to the platform? Start with the beta quickstart: install, token, list your clusters, deploy a minimal module.
The Manta SDK is a unified Python library for distributed computing and federated learning on the Manta platform. It combines the functionality of both the high-level API client and the lightweight task execution runtime into a single, flexible package.
Features
- 🚀 Unified API: Single package for both client operations and task execution
- 📦 Modular Installation: Install only what you need with optional dependencies
- 🐳 Container Optimized: Lightweight
[light]mode for minimal container footprint - 🔄 Async/Sync APIs: Full async support with sync wrappers for convenience
- 🖥️ CLI Tools: Command-line interface for cluster and swarm management
- 🔒 Secure: JWT authentication with optional mTLS support

Installation Options
Every published release is a pre-release, so each command below carries the version specifier that lets pip select one. The extras are the ones pyproject.toml defines: light, sdk, examples, test, docs, code-analytics and all.
API Client
pip install "mantatech-sdk>=0.6b5.dev0"
The base install is enough to import manta.apis and deploy and manage swarms from your application.
For Task Execution
pip install "mantatech-sdk[light]>=0.6b5.dev0"
Adds numpy, used by the manta.light array helpers.
For CLI Usage
pip install "mantatech-sdk[sdk]>=0.6b5.dev0"
Adds the TOML/YAML configuration and cryptography dependencies the manta command-line tool uses.
Examples
pip install "mantatech-sdk[examples]>=0.6b5.dev0"
Adds marimo, torch and torchvision for the bundled examples.
Development Installation
pip install "mantatech-sdk[all]>=0.6b5.dev0"
Installs sdk, light, test, docs and code-analytics. It does not include examples.
Quick Start
API Client Usage
import manta
from manta.apis import AsyncUserAPI
import asyncio
async def main():
# Initialize API client
api = AsyncUserAPI(
token="your_jwt_token",
host="localhost",
port=50052
)
# Check service availability
available = await api.is_available()
print(f"Service available: {available}")
# Get cluster API for specific cluster
cluster_api = api.get_async_cluster_api("cluster_id")
# Deploy a swarm
swarm_overview = await cluster_api.deploy_swarm(swarm_definition)
print(f"Deployed swarm: {swarm_overview.swarm_id}")
# Stream results in real-time
async for result in cluster_api.stream_results(swarm_id, tag="metrics"):
print(f"Result: {result.data}")
if __name__ == "__main__":
asyncio.run(main())
Task Execution Usage (Inside Containers)
from manta.light import Local, World, Results, Task
import numpy as np
# Initialize task runtime
task = Task()
local = Local()
world = World()
results = Results()
# Load data from cluster
data = local.load_data("training_data")
# Get global parameters
global_model = world.get("model_weights")
# Perform computation
model = train_model(data, global_model)
accuracy = evaluate_model(model, data)
# Save results
results.save({"accuracy": accuracy}, tag="metrics")
world.set("model_weights", model.state_dict())
CLI Usage
# Configure connection
manta config set --host localhost --port 50052 --token your_jwt_token
# List available clusters
manta cluster list
# Deploy a swarm
manta simulation deploy --swarm-file swarm.py --cluster-id cluster_123
# Monitor swarm execution
manta simulation logs --swarm-id swarm_456
# Stop running swarm
manta simulation stop --swarm-id swarm_456
API Modules
manta.apis - High-Level Client SDK
Access via: from manta.apis import AsyncUserAPI or import manta; api = manta.api
AsyncUserAPI/UserAPI: User operations and swarm managementAsyncClusterAPI/ClusterAPI: Cluster-specific operationsSwarm,Task,Module: High-level swarm definition classes
manta.light - Task Execution Runtime
Access via: from manta.light import Local or import manta; light = manta.light
Local: Access to cluster data and local resourcesWorld: Global state management across tasksResults: Result saving and sharingTask: Task runtime information and utilities
Migration from Previous Packages
From manta-core
# Old import (still works - backwards compatible)
from manta import AsyncUserAPI, Swarm, Task
# New recommended import pattern
import manta
from manta.apis import AsyncUserAPI, Swarm, Task
# Or access via: api_module = manta.api
From manta-light
# Old import
from manta_light import Local, World, Results
# New import (same functionality)
from manta.light import Local, World, Results
Container Optimization
The SDK is designed for optimal container usage:
Light Mode (Recommended for Tasks):
- Install:
pip install "mantatech-sdk[light]>=0.6b5.dev0" - Contains: Task execution runtime
- Use case: Inside task containers
With the CLI (For Development):
- Install:
pip install "mantatech-sdk[sdk]>=0.6b5.dev0" - Contains: Client SDK + task runtime + the
mantaCLI's configuration dependencies - Use case: Development machines, CI/CD pipelines
Advanced Usage
Configuration
The SDK reads no MANTA_* environment variables. Connection settings come
from the arguments you pass, or from a configuration saved under
~/.manta/sdk/ by the manta CLI (which needs the [sdk] extra):
# Prompts for the host, the port and the token (masked as you type it)
manta sdk config init --interactive --name prod
import manta
from manta.apis import AsyncUserAPI
# From a saved configuration: the active one, or one by name
api = manta.configure_from_config("prod")
# Or sign in with your email and password
api = await AsyncUserAPI.sign_in(
"you@example.com", "your-password", host="api.manta-tech.io", port=443
)
Secure Connections
For production environments with mTLS:
from manta.apis import AsyncUserAPI
api = AsyncUserAPI(
token="your_jwt_token",
host="prod-manager.example.com",
port=50052,
cafile="/etc/manta/certs/ca.crt",
certfile="/etc/manta/certs/client.crt",
keyfile="/etc/manta/certs/client.key",
)
The synchronous UserAPI also accepts cert_folder="/etc/manta/certs", and
picks up ca.crt, client.crt and client.key from that folder.
Swarm Definition
Create complex swarms with task dependencies:
from manta.apis import Swarm, Task, Module
# Define algorithm module
module = Module(
name="federated_learning",
python_program="fl_trainer.py",
image="ghcr.io/mantatech/manta-light:pytorch"
)
# Define tasks with dependencies
aggregator = Task(
name="aggregator",
module=module,
command="python fl_trainer.py --role aggregator",
replicas=1
)
workers = Task(
name="worker",
module=module,
command="python fl_trainer.py --role worker",
replicas=5
)
# Create swarm
swarm = Swarm(
name="federated_mnist",
tasks=[aggregator, workers],
iteration=10,
circular=True
)
