NumPy is easy to use and pretty much interactive. You can also solve complex mathematical problems with ease.

One of the most compelling features of NumPy is the Array interface. You can use the library for expressing images and sound waves as an array of real numbers in N-dimensional. Apart from that, if you are a full-stack developer, NumPy is the ideal Python library for you.

4. Keras

Keras is one of the smartest Python libraries to date, which is an ideal choice if you fancy machine learning. It can display neural networks with ease, and when it comes to compiling models, processing data sets, or viewing graphs, Keras can be your best friend. Moreover, it can also work with other libraries like Theano or TensorFlow, which gives you an edge in backend jobs.

You will be surprised to know that you use Keras almost every day. Popular programs like Netflix, Uber, Yelp, Instacart, Zocdoc, Square, and much more use Keras. However, the most effective use of Keras is Neural Networking. That’s not all, you can do in-depth learning studies using this library as well.

5. PyTorch

If you are a developer and want to perform tensor computations, we believe the PyTorch library is your best option. It offers a variety of APIs to solve issues related to neural networks. PyTorch is a Torch-based machine learning library, which is not only open-source but also uses C wrapped in Lua.

Now, if we skip the technical part, you can use this library for natural language processing. PyTorch is better than a lot of other libraries. That is why it is getting plenty of attention. Some of its most important uses are Hybrid Front-end development and Distributed Training. Therefore, PyTorch justifies the list we have created.

6. LightGBM

The next on our list is LightGBM, which is popularly known as Gradient Boosting. Ideal for machine learning with new algorithms, by which you can redefine elementary models. LightGBM ensures quality in production, and at the same time, it is user-friendly. With Gradient Boosting, you can get faster training, and you are less likely to make errors.

You can use LightGBM for typical machine learning. It offers high scalability compared to other libraries, and you can expect faster Gradient Boosting. LightGBM is often the first choice for Python users so, you should give it a try.

7. Eli5

If you want accurate predictions in machine learning, then we recommend you Eli5. It is a robust Python library that offers an ideal blending of visualization with debugging. So, you can track all the working steps of an algorithm. That’s not all, with Eli5, you can work with other libraries like XGBoost, Lightning, Scikit-learn, and even Sklearn-Crfsuite.

Now, if we want to discuss the use of Eli5; you can use it in solving Mathematical equations with ease. You can rely on Eli5 while working with other Python packages. Moreover, you can run Legacy applications and find new ways. Therefore, it should be worth your time.

8. SciPy

If you are an application developer or an engineer, you should check out this fantastic Python library – SciPy. With SciPy, you can optimize the modules and perform a bunch of other stuff. You can work with SciPy along with NumPy to get the most out of the array feature. Apart from that, you can do numerical routines with the help of this library without breaking a sweat.

One of the most important uses of SciPy is when it works along with Numpy to resolve mathematical functions. Also, it uses NumPy for basic data structure building. Additionally, you can do linear algebra, integration, and a whole bunch of equations. Therefore, all these prove you can rely on SciPy, and it is worth a shot.

9. Theano

If you are looking for a computational framework well, look no further as you can check out Theano. It is primarily a Python library that offers multi-dimensional computing arrays. It is ideal for production, and it can work with other libraries as well. With Theano, you can expect speedy performances, something you can rely on.

If you are new in software development, Theano can be your ally, which can handle complex computing. You can use it in Deep Learning research as well as creating new ones. With this, you can do projects related to the neural network thus, it is one of its kind according to many experts.

10. Pandas

The last on our list is Pandas, which is renowned for high-level data structuring. You can perform complex programs using Pandas, and you can translate data effortlessly. With this library, you can handle the data of an entire project, and the best part is the speed it operates. Something that many of its rivals fail to deliver.

You can use Pandas to fix bugs as well as improve the overall status of a project. It supports a wide range of APIs which are best for groping and sorting data. So, you can say the main purpose of Pandas is to use it in Data Analysis.


So, these are the list of libraries that you should consider if you are using Python. Now, please note that there are hundreds of libraries for Python that you can use as well. We have created a list of those libraries which are, in some ways, unique to one another.
