Languages used: Python

**Who is behind Pytorch?** A new paper from original PyTorch developers Adam Paszke, Sam Gross, Soumith Chintala, Gregory Chanan and 17 other researchers explores the inspiration behind the library, and makes the case for its unique marriage of speed and usability.

## who developed keras?

François Chollet**Is TensorFlow an API?** TensorFlow, open-sourced in late 2015, is the most popular deep learning framework. It is for both researchers and developers. write TensorFlow code in different languages: Python, JavaScript or SWIFT. train on CPU, GPU or TPU and deploy to mobile (Android / iOS), Web, Android Things, Raspberry Pi, and AIY kits etc.

## is theano still alive?

**Theano** is effectively **dead**. Many academic researchers in the field of deep learning rely on **Theano**, the grand-daddy of deep-learning frameworks, which is written in Python. **Theano** is a library that handles multidimensional arrays, like Numpy.

**What is keras vs TensorFlow?** Keras is a neural network library while TensorFlow is the open source library for a number of various tasks in machine learning. TensorFlow provides both high-level and low-level APIs while Keras provides only high-level APIs. Both frameworks thus provide high-level APIs for building and training models with ease.

## what is theano in Python?

**Theano** is a **Python** library that allows you to define, optimize, and evaluate mathematical expressions involving multi-dimensional arrays efficiently. **Theano** features: tight integration with NumPy – Use numpy. ndarray in **Theano**-compiled functions.

**What does keras mean?** Keras is an open-source neural-network library written in Python. It is capable of running on top of TensorFlow, Microsoft Cognitive Toolkit, Theano, or PlaidML. Designed to enable fast experimentation with deep neural networks, it focuses on being user-friendly, modular, and extensible.

### Is theano a deep learning framework?

**Theano**. **Theano**, one of the first **deep learning** libraries, is a python library and optimizing compiler for manipulating and evaluating Tensor operations. **Theano** uses numpy syntax, which is then compiled to perform efficiently on either a CPU or a GPU.

**Is keras part of TensorFlow?** As background, Keras is a high-level Python neural networks library that runs on top of either TensorFlow or Theano. There are other high level Python neural networks libraries that can be used on top of TensorFlow, such as TF-Slim, although these are less developed and not part of core TensorFlow.

### Is TensorFlow a Python library?

Introduction to the Python Deep Learning Library TensorFlow. TensorFlow is a Python library for fast numerical computing created and released by Google. It is a foundation library that can be used to create Deep Learning models directly or by using wrapper libraries that simplify the process built on top of TensorFlow.

### Is keras easier than TensorFlow?

Tensorflow is the most famous library used in production for deep learning models. However TensorFlow is not that easy to use. On the other hand, Keras is a high level API built on TensorFlow (and can be used on top of Theano too). It is more user-friendly and easy to use as compared to TF.

### Why keras is used in Python?

Keras is an Open Source Neural Network library written in Python that runs on top of Theano or Tensorflow. It is designed to be modular, fast and easy to use. Keras doesn't handle Low-Level API such as making the computational graph, making tensors or other variables because it has been handled by the "backend" engine.

### Does keras use GPU?

Yes you can run keras models on GPU. Few things you will have to check first. All the best.

### Is TensorFlow open source?

TensorFlow is an open source software library for numerical computation using data-flow graphs. TensorFlow is cross-platform. It runs on nearly everything: GPUs and CPUs—including mobile and embedded platforms—and even tensor processing units (TPUs), which are specialized hardware to do tensor math on.

#### Is keras free?

Keras is a powerful and easy-to-use free open source Python library for developing and evaluating deep learning models. It wraps the efficient numerical computation libraries Theano and TensorFlow and allows you to define and train neural network models in just a few lines of code.

#### What is the use of PyTorch?

PyTorch is an open-source machine learning library for Python, based on Torch, used for applications such as natural language processing. It is primarily developed by Facebook's artificial-intelligence research group, and Uber's "Pyro" Probabilistic programming language software is built on it.

#### What is deep learning AI?

Deep learning is a subset of machine learning in artificial intelligence (AI) that has networks capable of learning unsupervised from data that is unstructured or unlabeled. Also known as deep neural learning or deep neural network.

#### Which Python library is used for machine learning?

NumPy
