Deeplearning4j is a suite of tools for running deep learning on the JVM, developed under the Eclipse foundation. It is the only framework that allows training models from Java while interoperating with the Python ecosystem through Python execution, model import support, and integration with other runtimes like TensorFlow and ONNX. It supports use cases such as importing and retraining models (PyTorch, TensorFlow, Keras) and deploying them in JVM microservices, mobile devices, IoT, and Apache Spark environments. The suite includes submodules like Samediff, Nd4j, Libnd4j, Python4j, Apache Spark Integration, and Datavec.
