Keras, TensorFlow, and PyTorch are among the top three frameworks that are preferred by Data Scientists as well as beginners in the field of  Deep Learning. This comparison on Keras vs TensorFlow vs PyTorch will provide you with a crisp knowledge about the top Deep Learning Frameworks and help you find out which one is suitable for you. In this blog you will get a complete insight into the above three frameworks in the following sequence:
  • Introduction to Keras, TensorFlow & PyTorch
  • Comparison Factors
  • Final Verdict

Introduction
Keras
Keras is an open-source neural network library written in Python. It is capable of running on top of TensorFlow. It is designed to enable fast experimentation with deep neural networks.

TensorFlow
TensorFlow is an open-source software library for dataflow programming across a range of tasks. It is a symbolic math library that is used for machine learning applications like neural networks.

PyTorch
PyTorch is an open-source machine learning library for Python, based on Torch. It is used for applications such as natural language processing and was developed by Facebookâ??s AI research group.

Comparison Factors
All three frameworks are related to each other and also have certain basic differences that distinguish them from one another.

So let's have a look at the parameters that distinguish them:
Level of API
Keras is a high-level API capable of running on top of TensorFlow, CNTK, and Theano. It has gained favor for its ease of use and syntactic simplicity, facilitating fast development.

TensorFlow is a framework that provides both high and low-level APIs. Pytorch, on the other hand, is a lower-level API focused on direct work with array expressions. It has gained immense interest in the last year, becoming a preferred solution for academic research, and applications of deep learning requiring optimizing custom expressions.

Speed
The performance is comparatively slower in Keras whereas Tensorflow and PyTorch provide a similar pace which is fast and suitable for high performance.

Architecture
Keras has a simple architecture. It is more readable and concise. Tensorflow, on the other hand, is not very easy to use even though it provides Keras as a framework that makes work easier. PyTorch has a complex architecture and the readability is less when compared to Keras.

Debugging
In Keras, there is usually very less frequent need to debug simple networks. But in the case of TensorFlow, it is quite difficult to perform debugging. Pytorch, on the other hand, has better debugging capabilities as compared to the other two.

Dataset
Keras is usually used for small datasets as it is comparatively slower. On the other hand, TensorFlow and PyTorch are used for high-performance models and large datasets that require fast execution.

Popularity
With the increasing demand in the field of Data Science, there has been an enormous growth of Deep learning technology in the industry. With this, all three frameworks have gained quite a lot of popularity. Keras tops the list followed by TensorFlow and PyTorch. It has gained immense popularity due to its simplicity when compared to the other two.

Final Verdict
Now with this, we come to an end of this comparison on Keras vs TensorFlow vs PyTorch. I hope you guys enjoyed this article and understood which Deep Learning Framework is most suitable for you.
