Install the latest nnabla by:

pip install nnabla
pip install nnabla-ext-cuda110 # For CUDA version 11.0.3 users

You can also install the cuda extension with specific versions from one of the following. See also FAQ

  • nnabla-ext-cuda110 (CUDA 11.0.3 x cuDNN 8.0)
  • nnabla-ext-cuda114 (CUDA 11.4.3 x cuDNN 8.0)
pip install nnabla
pip install nnabla_ext_cuda110  # For CUDA 11.0.3 x cuDNN 8.0 users

The nnabla cuda extension supports both centralized and distributed training.
Below packages detect MPI and NCCL2 installed on your system. If either one
of then is unavailable, distributed training is disabled.

  • nnabla-ext-cuda110 (Ubuntu18.04 default)
  • nnabla-ext-cuda114 (Ubuntu18.04 default)

Additional setup may be required depending on your OS or environment. Please check Python Package Installation Guide for details.
