良い感じのおもちゃを手に入れたのでとりあえず個人的なセットアップのメモ✍
このメモを書いたときの JetPack のバージョンは 4.4 でした😌

起動らへんまで

  1. Jetson Download Center とかから Jetson Nano Developer Kit SD Card Image をダウンロードする。
  2. microSDXC にダウンロードしたイメージ (zip 圧縮されてたので解凍して中身の .img ファイル) を書き込む。
    ※ 今回は Mac で作業してたので Etcher なるソフトを使いました。
  3. 向きに気をつけて microSDXC を Jetson Nano に挿入する。
  4. (モニタとかキーボードとかマウスとか繋いで) USB を挿したら自動的に目覚めるはず。
  5. Ubuntu なので普通に雰囲気でユーザ設定とかをする。

めっちゃ Ubuntu だけど NVIDIA 感あってかっこよい😊

とりあえず apt update & apt upgrade

脳死で

$ sudo apt update

してみると、

おや😲

ということで、とりま↓

$ sudo apt install ca-certificates

して、もっかい試してみたらちゃんと通りました😌

Python 環境

Anaconda 使えないので Python 環境どうしよっかな。。。と悩んだ結果、とりあえず pipenv 使ってみようかね。となったので

$ curl https://raw.githubusercontent.com/pypa/pipenv/master/get-pipenv.py | python

で pipenv を入れました (root で)。setup-tools ないよと言われたので先に↓で入れとくと良さげかも😌

$ sudo apt install python-setuptools

pipenv 初心者かつ、そういう記事ではないので詳しい使い方はドキュメントとかを読んでください🙇
