Kaldi Release 19.07
The NVIDIA container image for Kaldi, release 19.07, is available on NGC.
Contents of the Kaldi container
- Ubuntu 18.04 including Python 3.5
- NVIDIA CUDA 10.1.168 including cuBLAS 10.2.0.168
- NVIDIA cuDNN 7.6.1
- NVIDIA NCCL 2.4.7 (optimized for NVLink™ )
- MLNX_OFED +3.4
- OpenMPI 3.1.3
- TensorRT 5.1.5
Release 19.07 is based on NVIDIA CUDA 10.1.168, which requires NVIDIA Driver release 418.67. However, if you are running on Tesla (Tesla V100, Tesla P4, Tesla P40, or Tesla P100), you may use NVIDIA driver release 384.111+ or 410. The CUDA driver's compatibility package only supports particular drivers. For a complete list of supported drivers, see the CUDA Application Compatibility topic. For more information, see CUDA Compatibility and Upgrades.
Release 19.07 supports CUDA compute capability 6.0 and higher. This corresponds to GPUs in the Pascal, Volta, and Turing 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.
