Python continues to lead the pack when working in machine learning, AI deep learning, and data science. The world of programming is amazed by Python’s growing popularity and power. Its massive application possibilities have made it much more accessible for newcomers and beginners in the field to pick Python as their first programming language to master. Because of its wide-ranging application in computing science, many Python libraries have emerged, which have proved to be most popular with deep learning and machine learning experts. Here, we’ve identified the most popular Python libraries that deep-learning and machine learning professionals must be aware of in 2022.

Before moving ahead, let’s know a bit about **Why is Python not a good choice for a project?**.

#### Table of Contents

**NumPy**

It is no doubt that NumPy is among the most well-known Python libraries, which can be utilized for large multidimensional arrays and matrix processing using an extensive collection of high-level mathematical functions. It is crucial to perform efficient scientific fundamental computations in machine learning, and it is especially beneficial in linear algebra and other tasks.

**Theano**

Theano is an algorithm for numeric computation Python library specifically designed for deep learning and machine learning. It allows efficient design, optimization, and evaluation of mathematical formulas and matrix calculations, which use multidimensional arrays to build advanced models of deep understanding.

**Caffe**

The list is not complete without Caffe, as it is among the most popular deep-learning libraries that use Python. The library, created in collaboration with Berkeley Vision and Learning Center Berkeley Vision and Learning Center, is flexible and fast and extremely popular for industrialists and academics looking to develop cutting-edge applications.

**TensorFlow**

TensorFlow is an open-source library utilized for computational computation that uses data flow graphs. The main advantage of using TensorFlow is distributed computing, especially with several GPUs.

**SciPy**

SciPy is an entirely free and open-source library built upon NumPy, and it is among the most popular Python libraries for technical and scientific computation with large data sets. SciPy comes with built-in modules to optimize arrays as well as linear algebra.
