8 of The Most Popular Machine Learning Tools

Explore the top 8 machine learning tools essential for modern ML practitioners. From Azure to Vertex AI, discover their key features and uses.
Dec 2023  · 12 min read

Everybody needs tools. Builders, plumbers, electricians - you name it. Tools are a necessary part of every craftsperson’s toolkit, including machine learning practitioners. Machine learning practitioners need tools to help them build, train, and deploy machine learning models rapidly.

A crop of new machine learning tools pops up each year to help simplify this process and advance the field. To remain at the cutting edge of the field, it’s vital you at least know what these tools are, how they help, their key features, strengths, and weaknesses, as well as some ideal use cases.

In this article, we’re going to cover those topics and then compare each tool, so you know how to select the best ones for your projects.

The Importance of Machine Learning Tools

Imagine a world where each time you wanted to use a machine learning algorithm, you had to code it entirely from scratch. Here's another one: imagine a world where whenever you've completed an experiment, you must write the outcomes on a piece of paper, and when you’ve deployed models, buying new servers is the only way to scale your applications.

Quite frankly, many of these aren’t so hard to believe for those who’ve been around long enough because it was their reality. Many couldn’t enter the field because they couldn't translate mathematical formulas into code — maybe mathematics wasn’t their background. The introduction of various tools lowered this barrier to entry.

Nowadays, it’s possible to implement a machine algorithm without fully knowing the inner workings or mathematical formulas that govern them. Note this doesn’t mean you don’t need to know (you do); it just means you don’t need to know to implement the algorithm.

Another reason tools in machine learning are important is because they speed up processes. For example, since it’s no longer necessary to code entire algorithms from scratch, it’s possible to perform many experiments in less time, which means you’ll likely find the champion model to take to production faster.

Ultimately, machine learning tools simplify complex tasks and speed up the process of taking models from the research environment to production.

Choosing the Right Machine Learning Tool

Like most things in technology, the answer to “What machine learning tool should I use for [insert some situation]?” is, “It depends.”

When choosing a tool, the most important thing to consider is your needs, such as:

  • What am I trying to do?
  • What are the constraints?
  • What level of customization do I need?

All tools aren’t the same. For example, TensorFlow was developed by Google Brain researchers to advance key areas of machine learning and promote a better theoretical understanding of deep learning. In contrast, PyTorch was created to provide flexibility and speed during the development of deep learning models.

Although they seek to solve the same problem (simplify the process of building deep learning models), the way they go about it is different.

This is a common theme in machine learning; thus, it’s best to understand what you’re trying to achieve and then select the machine learning tools that make the process as simple as possible.


Tools are necessary for every kind of craftsperson, including machine learning practitioners. ML practitioners often leverage them to rapidly build, train, and deploy machine learning models. In this article, I gave you 8 of the most popular machine learning tools.

They are:

  1. Microsoft Azure Machine Learning
  2. Amazon SageMaker
  3. BigML
  4. TensorFlow
  5. PyTorch
  6. Apache Mahout
  7. Weka
  8. Vertex AI

The main purpose of these tools is to speed up the process of developing machine learning models and moving them from research to a production environment.
