Installation on Linux

Prerequisites

This installation instruction describes how to install NNabla using pip on almost any Linux 64-bit systems.

The supported Python versions for provided binary packages are 2.7, 3.5 3.6. It is recommended to use Miniconda as a Python distribution. The following is a simple procedure to install Miniconda Python.

wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh
bash Miniconda3-latest-Linux-x86_64.sh -b -p {installation path e.g. ~/miniconda}
# You have to set an environment variable PATH accordingly
# to enable the installed ``Python`` and the ``conda`` system.
echo 'export PATH=<installation path>/bin:$PATH' >> ~/.bashrc
# Restart your bash or source ~/.bashrc

# Switch the default Python version
conda install -y python={version number e.g. 3.6}

Installation

FAQ

Q. I use Anaconda, and the installation fails.

Use libgcc 5 and numpy 1.13.0 or the greater, and note that numba depends on the older numpy so please uninstall numba first (The following is for Python2).

conda create -n py2 python=2.7 anaconda  # if necessary
source activate py2
conda install libgcc
conda install -c anaconda numpy=1.13.0

Then, you can follow the usual installation workflow.

Q. I want to use another linux distribution.

We actually tested other linux distributions and versions; Ubuntu 14.04, CentOS 6.9, 7.3, Fedora 23, 25, 26, and RHEL 7.3 on various environments; Baremetal server, AWS instance, and/or Docker machine. Thus, you can install in almost the same way described here. The details of how-to-install for each are coming soon.
