Common server utilities for Matrice.ai services

Matrice Common Library

matrice_common is a high-performance Python package providing reusable utilities for Matrice.ai services. It offers production-ready components for authentication, API communication, streaming, video processing, and more.

🚀 Quick Start

Installation

pip install --index-url https://test.pypi.org/simple/ matrice_common

Basic Usage

from matrice_common.rpc import RPC
from matrice_common.session import create_session

# Initialize RPC client
rpc = RPC(
    access_key="your_access_key",
    secret_key="your_secret_key"
)

# Make API requests
response = rpc.get("/v1/endpoint")
data = rpc.post("/v1/resource", payload={"key": "value"})

# Create a session
session = create_session(
    access_key="your_access_key",
    secret_key="your_secret_key"
)

# Create a project
project = session.create_classification_project(
    name="My Project",
    description="AI classification project"
)

💡 Examples

Async API Calls

import asyncio
from matrice_common.rpc import RPC

async def fetch_data():
    rpc = RPC(access_key="...", secret_key="...")

    # Concurrent requests
    results = await asyncio.gather(
        rpc.get_async("/v1/users"),
        rpc.get_async("/v1/projects"),
        rpc.get_async("/v1/datasets")
    )

    return results

asyncio.run(fetch_data())

Streaming with Kafka

from matrice_common.stream.matrice_stream import MatriceStream, StreamType

# Create stream
stream = MatriceStream(
    stream_type=StreamType.KAFKA,
    access_key="...",
    secret_key="..."
)

# Setup and use
stream.setup(topic_or_stream_name="my-topic")
stream.add_message({"data": "value", "timestamp": "2025-01-01T12:00:00Z"})

# Receive messages
message = stream.get_message(timeout=30)
if message:
    print(f"Received: {message}")

stream.close()

Error Handling

from matrice_common.utils import log_errors, AppError, ErrorType, get_deduplication_config

# Configure deduplication (or use environment variables)
# export MATRICE_ERROR_DEDUPLICATION_ENABLED=true
# export MATRICE_ERROR_CACHE_TTL_SECONDS=1800  # 30 minutes

# Use service_name to properly track errors per service
@log_errors(service_name="my_service", raise_exception=False)
def process_data(data):
    """Automatically logs errors to Sentry and Kafka with deduplication."""
    if not data:
        raise ValueError("Data cannot be empty")

    # Process data
    return result

# Errors are automatically logged and deduplicated
result = process_data(my_data)

# Check deduplication config
print(get_deduplication_config())
# Output: {'enabled': True, 'ttl_seconds': 900, 'max_cache_size': 1000, 'current_cache_size': 0}

Video Encoding

from matrice_common.video.h265_processor import encode_frame_h265, decode_frame_h265
from PIL import Image

# Load and encode frame
frame = Image.open("frame.jpg")
encoded = encode_frame_h265(frame, quality=23, preset="medium")

# Decode frame
decoded = decode_frame_h265(encoded)
decoded.show()
