One of the top Python libraries currently has over 15 million downloads from the Python Package Index. Its flexibility makes it easy to build everything from chatbots to self-driving cars. Companies like  Airbnb and Uber also use TensorFlow to power their AI products.

It’s not the only powerful library out there, but its popularity is a testament to its usefulness in machine learning projects.


#2. Scikit-learn

Scikit-learn provides users with feature engineering for data sets, prediction algorithms, preprocessing tools, model selection, and many others. 

The library’s creators have worked hard to make it the “go-to” resource for beginners and experts alike. Scikit-learn has a simple, clean API that makes everything from regression analysis to hypothesis testing a breeze. 

Moreover, the library’s flexibility has proved to be a significant boon for those working in different fields. For example, it’s been helpful in the development of recommender systems and fraud detection tools.

As of Oct 2021, there are more than 24,296,500 downloads of Scikit-learn. (Source: PyPI Stats)

NumPy is the ultimate package required for scientific computing in Python. It provides users with high-level commands that are used to create efficient, multidimensional arrays.

The library’s creators have focused on making it fast, easy to use, and compatible with other libraries within the SciPy stack.  For example, NumPy was built to work with SciPy’s signal processing, random number generation, and statistics functions.

As per Google Trends, there has been a continuous search for respondents ManyNumPy in the past five years.


#4. SciPy

A collection of algorithms and high-level commands to perform advanced math functions, SciPy is relatively easy for beginners to learn. The library also provides extensive documentation that makes it helpful for experts working with large datasets.

It’s one of the most versatile libraries in the Python space because it can solve almost any scientific computing task.

It allows users to manipulate images, find derivatives, perform integration, and much more.  That said, SciPy isn’t just for mathematicians. It also provides tools for quantum physics, machine learning, signal processing, and even spectral analysis.

#5. Theano

Theano is a Python library that’s capable of running machine learning algorithms. It was designed to compile Python code into machine language for faster and more efficient computation.

In GitHub, Theano has 9.5k Stars and 2.5k Forks.9835928262Theano takes advantage of CPUs and GPUs to provide users with faster processing speeds. It’s capable of optimizing any Python function, making it easier to work with data in large quantities.

It also lets you manage multi-dimensional arrays without worrying about performance issues. That said, Theano is more than just a fast alternative for intensive computing tasks; it’s also a useful machine learning library for developers.

Besides, it is also a good idea to hire Python developers in India from a company that provides the best Python development services.

#6. Keras9835929491While many Python frameworks for machine learning focus on the low-level details of deep learning, Keras is different because it’s high level. This means that you can perform deep learning without worrying about the underlying mechanics.

Keras provides an easy-to-use API that allows you to build and train neural networks without the complicated syntax of other libraries. Since it’s based on TensorFlow, Keras can also run all models developed using Google’s library.

It’s used by data scientists and deep learning practitioners to create complex models that can run on CPUs or GPUs. Moreover, it offers a simple API to define custom layers and runs efficiently on the CPU (not just GPU). It uses Theano and TensorFlow as its backend so that you can develop your models from scratch.

#7. PyTorch

Facebook’s Pytorch was released as an alternative to Google’s TensorFlow in late 2016. It quickly became one of the top Python frameworks for machine learning with a strong community of contributors.

PyTorch is capable of dynamic computation graphs, allowing for fast prototyping. It also supports CUDA to take advantage of GPUs for faster training.

It has since become an industry standard among players like Salesforce, OpenAI, and Intel (who used it to build their latest search engine ).

#8. Pandas9835931501Pandas is a Python library that’s often used for data engineering and data analysis. It provides users with unique feature sets, including high-performance data structures and time series capabilities.

However, it is fast, flexible, easy to use, and a powerful open-source alternative to expensive commercial data analysis software. Pandas is particularly useful for in-depth analysis of finance, statistics, social science, and engineering data.

Moreover, Pandas can create highly complex indexes, which are helpful when trying to find data points within large datasets. Plus, if you look at the Stack Overflow 2021 survey, over 28% of respondents prefer using Pandas in their projects.9835932460
#9. Spark ML

Spark is incredibly fast & one of the well-recognized Python libraries for machine learning used for big data processing. It allows users to build distributed pipelines that can run across clusters of machines without any code changes.

Since it’s optimized for distributed computing, Spark can process data much faster than other machine learning libraries.

Additionally, it’s capable of automating the most time-consuming parts of building analytical pipelines. This simplifies identifying patterns in data and discovering insights that can be used to make predictions.

#10. NLTK

Natural Language Toolkit (NLTK) is a Python library that focuses on machine learning and NLP (natural language processing). NLTK is designed to handle tasks like tokenizing text, identifying parts of speech, and generating parsing trees, among other things.

NLTK also provides helpful methods for normalizing tokens and handling orthography (spelling) differences between languages.

This library makes it easier to build applications that use text as input and output, such as chatbots and text-to-speech generators. Besides, it has 10.3k Stars and 2.5k Fork.9835932678Conclusion

Machine learning is a complex topic that requires a lot of time and effort to master. Fortunately, the Python machine learning library & framework ecosystem is overgrowing to meet tech needs.
