Getting Started with Mars: Your Unified Framework for Large-Scale Data Computation

Mars is a tensor-based unified framework designed for efficient large-scale data computation. By scaling libraries like NumPy, Pandas, and Scikit-learn, Mars enhances their performance while offering users a user-friendly experience. In this article, we’ll cover the essentials for installing Mars and getting started with basic operations.

How to Install Mars

Getting Mars up and running on your computer is straightforward. Follow the steps below to install Mars using pip:

pip install pymars

Installation for Developers

If you’re keen on contributing to Mars, you can install it for development purposes. Here’s how:

git clone https://github.com/mars-project/mars.git
cd mars
pip install -e .[dev]

For further details about the installation process, refer to the installation documentation.

Understanding Mars: An Analogy

Think of Mars as a sophisticated chef in a large kitchen. The chef (Mars) can use various pots and pans (libraries like NumPy, Pandas, and Scikit-learn) to cook delicious meals (data computations). Instead of being constrained to a single recipe, the chef can prepare multiple dishes simultaneously, coordinating all the elements seamlessly. This allows for a more efficient and faster cooking process, enabling the chef to serve a banquet of data insights rather than just a simple meal.

Getting Started with Mars Session

To begin using Mars, you can either start a new session locally or connect to an already initialized Mars cluster:

import mars
mars.new_session()

For connecting to a Mars cluster:

import mars
mars.new_session(http='web_ip:ui_port')

Mars Tensor: The Familiar Interface

Mars Tensor offers an interface similar to NumPy, making it easy for users transitioning from NumPy to Mars. Here’s a simple example:

import numpy as np
import mars.tensor as mt

N = 200_000_000
a = np.random.uniform(-1, 1, size=(N, 2))      # Using NumPy
print((np.linalg.norm(a, axis=1).sum() * 4 / N)) 

a = mt.random.uniform(-1, 1, size=(N, 2))      # Using Mars
print((mt.linalg.norm(a, axis=1).sum() * 4 / N).execute()) 

Troubleshooting Tips

• If you encounter issues during installation, check your Python environment, as incompatible setups may lead to installation failures.
• For performance issues, ensure you are utilizing the latest version of Mars.
• Consider checking the documentation for specific integrations like TensorFlow and PyTorch if you are looking to broaden your applications.
