What are the Differences between TensorFlow, PyTorch, and Keras?

The comparison between TensorFlow, PyTorch, and Keras is an essential requirement to figure out which option is the best for you. However, it is difficult to differentiate the three frameworks due to the availability of powerful features in each framework. Here is an overview of the comparison between TensorFlow, PyTorch, and Keras based on different factors. 

  • Core Features 

The most important factor in answering queries like “Which is better, Keras or PyTorch or TensorFlow?” focuses on the core features of the frameworks. A review of the core features of TensorFlow, PyTorch, and Keras can help identify their power for machine learning projects.

TensorFlow offers promising features such as TensorBoard, parallel training, and feature columns. It also facilitates easier training on CPU and GPU. TensorBoard serves as an interactive visualization toolset that helps you understand, debug, and optimize TensorFlow programs. 

Feature columns in TensorFlow are high-level abstractions that help in transformation of raw data into formats tailored for machine learning. In addition, TensorFlow also supports parallel training that involves distributed computing, which can reduce training times. 

Keras stands out in the PyTorch vs. TensorFlow vs. Keras debate with its diverse range of features. It offers a user-friendly API that enables better prospects for familiarizing with deep learning. Keras also offers backend support with the strength of Theano, TensorFlow, and Microsoft CNTK. It is a high-level API that can support faster development of models within a few lines of code. On top of it, Keras offers a collection of pre-trained models that you can use for different machine-learning tasks.

PyTorch is also a powerful framework tailored for machine learning and deep learning workloads. The notable features of PyTorch include Tensor computation, dynamic graph computation, TorchScript, and automatic differentiation. PyTorch offers a multidimensional array in the form of a Tensor that could work on GPUs to achieve faster computation. 

The framework also leverages dynamic computation graphs that can enable flexibility in development and modification of models. TorchScript is a trusted feature for serialization of PyTorch models that ensures compatibility with C++ environments and readiness for production. PyTorch also leverages automatic differentiation alongside gradient computation for simplification of neural network backpropagation and training.

  • API Level 

Another important factor in the comparison between TensorFlow, PyTorch, and Keras is the API level of the frameworks. 

The PyTorch vs. TensorFlow comparison places TensorFlow at an advantage with the facility of high-level and low-level APIs.

On the other hand, PyTorch is a low-level API that supports working directly with array expressions. Therefore, it has become more popular for academic research as well as deep learning applications that require optimization of custom expressions. 

Keras is a high-level API that can run on Theano, TensorFlow, and CNTK. It has become a favorite pick for machine learning researchers and developers for its easier usability and simple syntax that can ensure faster development.

  • Architecture 

The architecture of machine learning frameworks also serves as a crucial factor for comparing them. It can help you with the TensorFlow vs. Keras vs. PyTorch debate to find out which framework offers better usability. TensorFlow has the most complex architecture and can be difficult to use for beginners.

On the other hand, PyTorch also has a complex architecture and creates setbacks for readability, especially for beginners. 

Keras stands out as the best pick in terms of architecture for its simplicity. On top of it, it is concise and offers better readability.

  • Debugging Capabilities 

Debugging is a crucial requirement of a machine learning framework to ensure that you create ML models free of errors. The Keras vs. TensorFlow comparison suggests that TensorFlow might not be suitable for projects that require a comprehensive assessment of projects before deployment. TensorFlow presents formidable setbacks for conducting debugging.

Keras also follows along the lines of TensorFlow in terms of debugging, albeit with a different perspective. It is a simple network, implying that you may not need debugging in most cases. 

PyTorch emerges as the winner for its impressive debugging capabilities as compared to Keras and TensorFlow.
