The library is a collection of tools and resources required to build deep learning and machine learning models. TensorFlow can be a great tool in deep learning for beginners because of its architectural and framework flexibility. The specialty of TensorFlow is its easy distribution of work onto multiple CPU or GPU cores by using Tensors. Tensors are containers that can store multi-dimensional data arrays as well as their linear operations. Although the primary function of TensorFlow is in the training and inference of deep neural networks, it can also be used for reinforcement learning and model visualization with its built-in tools.   

5. Keras

Keras is an open-source software library in Python that provides an interface for deep learning. It can run on top of TensorFlow, Theano, and CNTK and was developed focusing on fast experimentation with deep neural networks. Among other machine learning libraries, Keras can work with the widest range of data types, including arrays, text, and images. Keras is simple to use, reduces the cognitive load on developers, and is flexible in adopting principles of progressive disclosure of complexity, meaning reducing complexity by introducing information and function at increment levels. Also, Keras is powerful, providing industry-strength performance, and has been used by organizations like NASA and YouTube. These three key features of simplicity, flexibility and power of Keras make it one of the best machine learning libraries in Python. Keras offers fully functional models for creating neural networks integrating objectives, layers, optimizers, and activation functions. The library has many use cases, including fast and efficient prototyping, research work, and data modeling and visualization. 

6. Pandas

Pandas is a software library used for data science and analysis tasks in Python. It is built on top of the NumPy library, which provides numerical computing and specifies data extraction. Before building and training machine learning models, there is a need to prepare a dataset to clean and preprocess the data. Pandas help prepare the data with various tools for analyzing data in detail and is designed to work on relational and labeled data. The development of Pandas began in 2008 at AQR capital management by Wes McKinney, by the end of 2009, Pandas became open-sourced, and in 2015 Pandas became a NumFOCUS sponsored project. Now, Pandas is actively supported by a community of innovative developers and researchers worldwide, contributing to using the open-source Pandas library. It is one of the best Python libraries with high stability because of its backend code written in C or Python. Pandas provide high-level data structures, including two main types, one-dimensional series and two-dimensional DataFrame. Moreover, Pandas offers a variety of tools to manipulate series and DataFrames, so that users can prepare the dataset based on their needs. 

7. Matplotlib

Matplotlib is a data visualization or plotting library used in Python and is built upon SciPy and NumPy used for graphical representation. It is compatible with plotting data from SciPy, NumPy, and Pandas and provides a MATLAB-like interface that is exceptionally user-friendly. In 2002, John Hunter developed Matplotlib, which was originally a patch to IPython enabling interactive MATLAB-style plotting. Matplotlib provides an object-oriented API using standard GUI toolkits like GTL+, wxPython, Tkinter, or Qt and helps developers to build graphs and plots. The library can generate different types of graphs, including histograms, bar graphs, scatter plots, image plots, and more. Although Matplotlib plotting is limited to 2D graphs, the graphs are high-quality and publish-ready.
