deeplearning4j and Deeplearning4J

The second is an unofficial fork or mirror of the first, so they are competitors—the original deeplearning4j repository should be chosen over the abandoned mirror.

About deeplearning4j

deeplearning4j/deeplearning4j

Suite of tools for deploying and training deep learning models using the JVM. Highlights include model import for keras, tensorflow, and onnx/pytorch, a modular and tiny c++ library for running math code and a java based math library on top of the core c++ library. Also includes samediff: a pytorch/tensorflow like library for running deep learn...

SameDiff provides graph-based automatic differentiation with TensorFlow protobuf import, while ND4J's 500+ operations leverage LibND4J's optimized C++ backend with multi-platform support (AVX2/512 CPU, CUDA GPU, ARM). DataVec handles ETL across diverse formats (HDFS, Spark, images, video, audio, CSV), and the stack integrates Python4J for cpython execution—enabling end-to-end ML pipelines entirely on the JVM without leaving Java.
