# Does Tensorflow use Eigen?

## Does Tensorflow use Eigen?

tensorflow uses the Tensor module of Eigen (which is mostly maintained by the main author of tensorflow).

Is Eigen open source?

Eigen is open-source software licensed under the Mozilla Public License 2.0 since version 3.1. Eigen is implemented using the expression templates metaprogramming technique, meaning it builds expression trees at compile time and generates custom code to evaluate these.

### How does CMake create Eigen?

How to use Eigen3 with CMake

2. Unzip it and create the build directory in the folder of the source folder;
3. Run cmake with cmake -G “MinGW Makefiles” ../ -DCMAKE_INSTALL_PREFIX=/path/to/installation/folder ;
4. Run make with make install ;

Who created eigenvalues?

Finding the eigenvectors and eigenvalues for a linear transformation is often done using matrix algebra, first developed in the mid-19th century by the English mathematician Arthur Cayley. His work formed the foundation for modern linear algebra.

#### Is TensorFlow a C++ or Python?

The most important thing to realize about TensorFlow is that, for the most part, the core is not written in Python: It’s written in a combination of highly-optimized C++ and CUDA (Nvidia’s language for programming GPUs).

What is the difference between a tensor and a NumPy array?

An array is a grid of values that contains raw data and we use it to locate and interpret elements in the raw data. The difference between a NumPy array and a tensor is that the tensors are backed by the accelerator memory like GPU and they are immutable, unlike NumPy arrays.

## How do I add Eigen to Visual Studio?

To install eigen just double click on C:/workspace/eigen-3.3. 4/build-vc14/Eigen3. sln solution file. This action will open eigen project in Visual Studio C++ 14 2015.

What is Eigen?

(January 2016) ( Learn how and when to remove this template message) Eigen is a high-level C++ library of template headers for linear algebra, matrix and vector operations, geometrical transformations, numerical solvers and related algorithms. Eigen is open-source software licensed under the Mozilla Public License 2.0 since version 3.1.1.

### What do I need to install Eigen?

In order to use Eigen, you just need to download and extract Eigen’s source code (see the wiki for download instructions). In fact, the header files in the Eigen subdirectory are the only files required to compile programs using Eigen. The header files are the same for all platforms. It is not necessary to use CMake or install anything.

How to create a wiki site?

The simplest and easiest way to create a wiki site is by using Google Sites. You donâ€™t need technical know-how, plus its user-friendly interface lets you create easy-to-use and visually appealing wikis. 1. Sign up for an account in Google to create a wiki site with Google sites.

#### What is eigenspace and eigenbasis?

The set of all eigenvectors of T corresponding to the same eigenvalue, together with the zero vector, is called an eigenspace, or the characteristic space of T associated with that eigenvalue. [10] If a set of eigenvectors of T forms a basis of the domain of T , then this basis is called an eigenbasis .
