The field of data science relies heavily on the predictive capability of Machine Learning (ML) algorithms. Python offers an opportune playground for experimenting with these algorithms due to the readability and syntactical efficiency of the language. The vast availability of ML libraries accessible to Python users makes it an even more attractive solution to interpret the immense amount of data available today.

This article explores the top 10 ML packages that you need to know, as well as the advantages and disadvantages of each.

 

Top 10 ML Frameworks and Libraries

A Python framework is an interface or tool that allows developers to build ML models easily, without getting into the depth of the underlying algorithms.

Python libraries are specific files containing pre-written code that can be imported into your code base by using Python’s import feature. This increases your code reusability.

A Python framework can be a collection of libraries intended to build a model (e.g., machine learning) easily, without having to know the details of the underlying algorithms. An ML developer, however, must at least know how the algorithms work in order to know what results to expect, as well as how to validate them.

Now that we know the difference between a Python framework and a library, let’s get right to the countdown of the top 10 Python packages for machine learning.
