NVIDIA Jetson Nano初期設定①
SDカードなどを用いて、最初のOSイメージを作成し、Jetson Nanoを起動させます。
参考記事：Jetson Nano DeveloperをUSB 接続HDD/SSDルート構成
導入パッケージのアップデート
sudo apt update sudo apt upgrade -y
SWAP領域作成
SWAP領域は、ディスクアクセスが多いので、USB接続のHDD上にSWAP領域を作成しました。
/dev/sda1 swap swapをSWAPとしました。
また、各種ユーザー領域として、/dev/sda2のパーティションを作成し、両方のパーティションがブート時に自動マウントされるように、/etc/fstabに登録します。また、デバイス名（/dev/sda, /dev/sdbなど）はブート時に変わる場合もあるので、UUIDを用いて、fstabaへの設定をおすすめします。
UUID=75f4a210-081e-4572-8f0a-bffb1f3d84c3 swap swap defaults 0 0UUIDは、デバイスの以下のコマンドで確認出来ます。
root@jetson:~# ls -l /dev/disk/by-uuid total 0 lrwxrwxrwx 1 root root 10 10月 1 17:41 408b9b27-133c-475d-8b8e-151ebe91e6e9 -> ../../sda2 lrwxrwxrwx 1 root root 10 10月 1 17:41 75f4a210-081e-4572-8f0a-bffb1f3d84c3 -> ../../sda1
各種パッケージ導入
TensorFlow導入
NVIDIAの開発者コミュニティに記載されている内容で、インストールを行います。
https://docs.nvidia.com/deeplearning/frameworks/install-tf-jetson-platform/index.html#install
インストールコマンド実行により、以下のパッケージがインストールされました。
Successfully installed absl-py-0.8.0 astor-0.8.0 gast-0.2.2 google-pasta-0.1.7 grpcio-1.24.0 h5py-2.10.0 keras-applications-1.0.8 keras-preprocessing-1.1.0 markdown-3.1.1 numpy-1.17.2 protobuf-3.10.0rc1 setuptools-41.2.0 tensorboard-1.14.0 tensorflow-estimator-1.14.0 tensorflow-gpu-1.14.0+nv19.9 termcolor-1.1.0 werkzeug-0.16.0 wrapt-1.11.2
keras導入
インストール自体は 「pip3 install keras」 なのですが、依存関係のあるscipyのインストールに失敗します。scipyインストールに必要なライブラリーを事前にインストールしておきます。
以下インストール失敗時の画面コピーです。

OpenCV導入
NVIDIAのJetson Nanoでは、Open CVインストール向けに各種スクリプトが公開されています。基本的に、公開されているスクリプトを用いれば、簡単にOpenCVを導入することが出来ます。
NVIDIAのCuda対応のOpenCVが、各種バージョン簡単に導入できるのは、非常に助かります。
バージョン３系と４系を複数導入してみましたが、特に問題は起きませんでした。
