ND4J is an Apache 2.0-licensed scientific computing library for the JVM. By contributing code to this repository, you agree to make your contribution available under an Apache 2.0 license.
|
|
|
|
It is meant to be used in production environments rather than as a research tool, which means routines are designed to run fast with minimum RAM requirements.

|
## Main Features
|
|
|
|
- Versatile n-dimensional array object
|
|
- Multiplatform functionality including GPUs
|
|
- Linear algebra and signal processing functions
|
|
|
|
Specifics
|
|
|
|
- Supports GPUs via with the CUDA backend nd4j-cuda-7.5 and Native via nd4j-native.
|
|
- All of this is wrapped in a unifying interface.
|
|
- The API mimics the semantics of Numpy, Matlab and scikit-learn.

## Installation
|
|
|
|
To install ND4J, there are a couple of approaches, and more information can be found on the [DL4J website](https://deeplearning4j.org/docs/latest/nd4j-overview).
|
|
|
|
#### Install from Maven Central
|
|
|
|
1. Search for nd4j in the [Maven Central Repository](http://mvnrepository.com/search?q=nd4j) to find the available nd4j jars.
|
|
2. Include the appropriate dependency in your pom.xml.
|
|
|
|
#### Clone from the GitHub Repo

|
## Contribute
|
|
|
|
1. Check for open issues, or open a new issue to start a discussion around a feature idea or a bug.
|
|
2. If you feel uncomfortable or uncertain about an issue or your changes, feel free to contact us on Gitter using the link above.
|
|
3. Fork [the repository](https://github.com/deeplearning4j/nd4j.git) on GitHub to start making your changes to the **master** branch (or branch off of it).
|
|
4. Write a test, which shows that the bug was fixed or that the feature works as expected.
|
|
5. Note the repository follows
|
|
the [Google Java style](https://google.github.io/styleguide/javaguide.html)
|
|
with two modifications: 120-char column wrap and 4-spaces indentation. You
|
|
can format your code to this format by typing `mvn formatter:format` in the
|
|
subproject you work on, by using the `contrib/formatter.xml` at the root of
|
|
the repository to configure the Eclipse formatter, or by [using the INtellij
|
|
plugin](https://github.com/HPI-Information-Systems/Metanome/wiki/Installing-the-google-styleguide-settings-in-intellij-and-eclipse).
|
