Difference Between Keras vs TensorFlow vs PyTorch
The topmost three frameworks which are available as an open-source library are opted by data scientist in deep learning is PyTorch, TensorFlow, and Keras. The Keras is a neural network library scripted in python is Keras and can execute on the top layer of TensorFlow. It is specially designed for robust execution in deep neural networks. TensorFlow is an is used to perform multiple tasks in data flow programming and machine learning applications. PyTorch is a machine learning library that is used in natural language processing.

Key differences between Keras vs TensorFlow vs PyTorch
The major difference such as architecture, functions, programming, and various attributes of Keras, TensorFlow, and PyTorch are listed below.
- Level of API: Keras is an advanced level API that can run on the top layer of Theano, CNTK, and TensorFlow which has gained attention for its fast development and syntactic simplicity. TensorFlow works on both low level and high levels of API whereas PyTorch works only on API with low-level.
- Architecture and Performance of the framework: The architecture of Keras is simple, concise, and readable and the performance is too low. TensorFlow is rigid to use but supports Keras to perform better. The architecture of PyTorch is complex and less interpretable when compared to Keras. But the performance of TensorFlow and PyTorch is robust which gives the maximum performance and also gives high efficacy in larger datasets. As the performance of Keras is lower, it applies only to smaller datasets.
- Process of Debugging: The debugging of a simple network is provided by Keras which is required very often. But in TensorFlow, debugging is a very complicated process whereas PyTorch provides flexible debugging abilities when compared to Keras and TensorFlow. The operation of PyTorch in neural networks describes the effective computation time for debugging tools like PyCharm, ipdb, and PDB. But when it comes to TensorFlow, there is an advanced option called tfdbg which enables to operates at session scope with particular runtime by browsing all tensors. As it is inbuilt with python code, there is no separate use of PDB. TensorFlow is mode advanced than PyTorch and has a broad community than PyTorch and Keras.
- Suitability of the framework.: Keras is mostly preferred in the small dataset, and provides rapid prototyping and extended numerous back-end support whereas TensorFlow gives high performance and functionalities in object detection and can be implemented in a larger dataset. As the flexibility and debugging abilities of PyTorch are more it can be adapted in the minimum training time of the datasets.
- Performance of the framework in Neural Networks: PyTorch has multi-layer and cell level classes of developing recurrent networks. The object of the layers manages input data and one timestep in a unit cell and also represents RNN with bidirectional properties. So the numerous layers of the networks provide a suitable wrapper to the cell as there is no need for further optimization. TensorFlow comprises of dropout wrapper, multiple RNN cell, and cell level classes to implement deep neural networks. Keras comprises of fully connected layers, GRU and LSTM used for the creation of recurrent neural networks.
