Our verdict on Apache SINGA
Apache SINGA is an open-source deep-learning library for teams building, training, and running neural-network models. Its Python model and layer APIs support construction of neural networks, while C++ is also supported. The framework fits small, mid-market, and enterprise teams that want a compact, self-hosted tool for local or on-premises workloads across Linux, Windows, and macOS. CPU and CUDA-enabled GPU execution are supported, giving developers a choice of hardware for model development and operation.
SINGA is available as free open-source software rather than a tiered commercial product. The published installation options include pip, Docker, Conda, and source builds, so teams can align setup with their existing environment. Its ecosystem connections are focused: SINGA can load ONNX models for inference or retraining and export models created through its APIs to ONNX format; RDBMS is also listed as an integration. This makes it a practical fit for ONNX-centered workflows, while teams seeking a wider set of verified integrations may need to assess alternatives.
The standout capability is distributed training. SINGA supports data-parallel models across multiple GPUs and nodes, synchronizing distributed gradients with all-reduce. Automatic reverse-mode differentiation calculates gradients, and optimizers include SGD with momentum, Adam, RMSProp, and AdaGrad. Buffered-graph profiling exposes operator execution time for performance analysis. Documentation, examples, and community support are available for implementation and scaling. Choose SINGA when free licensing, Python APIs, GPU support, and distributed training are priorities; consider another framework if hosted deployment, broader workflow coverage, or a larger integration ecosystem matters more.
