Kaldi Release 23.05

The NVIDIA container image for Kaldi, release 23.05 is available on NGC.

Contents of the Kaldi container

This container image contains the complete source of the version of Kaldi in the /opt/kaldi directory. The container also includes the following:

Driver Requirements

Release 23.05 is based on CUDA 12.1.1, which requires NVIDIA Driver release 530 or later. However, if you are running on a data center GPU (for example, T4 or any other data center GPU), you can use NVIDIA driver release 450.51 (or later R450), 470.57 (or later R470), 510.47 (or later R510), 515.65 (or later R515), 525.85 (or later R525), or 530.30 (or later R530). The CUDA driver's compatibility package only supports particular drivers. Thus, users should upgrade from all R418, R440, R460, and R520 drivers, which are not forward-compatible with CUDA 12.1. For a complete list of supported drivers, see the CUDA Application Compatibility topic. For more information, see CUDA Compatibility and Upgrades.

GPU Requirements

Release 23.05 supports CUDA compute capability 6.0 and later. This corresponds to GPUs in the NVIDIA Pascal™, NVIDIA Volta™, NVIDIA Turing™, NVIDIA Ampere architecture, NVIDIA Hopper™, and NVIDIA Ada Lovelace architecture families. Specifically, for a list of GPUs that this compute capability corresponds to, see CUDA GPUs. For additional support details, see Deep Learning Frameworks Support Matrix.

Key Features and Enhancements

This Kaldi release includes the following key features and enhancements.

Packaged scripts

The Kaldi container comes with the following scripts:

  • /workspace/nvidia-examples/librispeech/prepare_data.sh, which downloads a trained model and data.
  • /workspace/nvidia-examples/librispeech/run_benchmark.sh, which runs inference on the trained model and data.

    Setting the ONLINE=1 environment variable makes the benchmark script run in online mode.
