Version 1.0.14 Release

Install the latest nnabla by:

pip install nnabla
pip install nnabla_ext_cuda  # For CUDA users

Users with python <= 3.4 may experience errors with pip install nnabla and pip install nnabla-ext-cuda.
■ Workaround
Please install matplotlib == 2.2.3 and re-install nnabla, nnabla_ext_cuda.

pip install matplotlib==2.2.3
pip install nnabla
pip install nnabla_ext_cuda

Note that CUDA 9.2 and cuDNN 7.3 are set as default if versions are not specified. You can also install the cuda extension with specific versions from one of the following. See also FAQ

• nnabla-ext-cuda80 (CUDA 8.0 x cuDNN 7.1)
• nnabla-ext-cuda90 (CUDA 9.0 x cuDNN 7.3(win), 7.4(linux))
• nnabla-ext-cuda92 (CUDA 9.2 x cuDNN 7.3(win), 7.4(linux))
• nnabla-ext-cuda100 (CUDA 10.0 x cuDNN 7.3(win), 7.4(linux))

pip install nnabla
pip install nnabla_ext_cuda92  # For CUDA 9.2 x cuDNN 7.3 users

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