シミュレータを起動します

シミュレーターを開始するのと同じ方法で開始します。

https://github.com/tawnkramer/gym-donkeycar/releases

シミュレータをメニュー画面にとどまらせます。

マルチプレイヤー

複数のDonkeyCarコンテナを同時に作成したい場合に使用します。実行しますpython multi_player.py。スクリプトは、作成したいレーサーの数を表示します。上記のように、DockerハブからDockerイメージをプルしているため、初めて実行するのに時間がかかります。

また、ブラウザからのコントロールもできます。

dockerへシェルのアクセス

モバイルアプリを起動します

モバイルアプリを起動すると、モバイルアプリは同じネットワーク上で（物理的または仮想的に）ロバの車を検出し始めます。あなたはこのようなものを見ているは​​ずです。

アプリ操作

仮想車を停止します

仮想ロバカーの使用が終了したら、stop.shまたはstop.batを使用してすべてのコンテナを停止します。stop.batは、システム内で実行中のすべてのDockerコンテナを強制終了することに注意してください。他のDockerコンテナを実行している場合は、このコマンドを使用しないように特に注意してください。

レーサー名を変更する

シングルプレイヤーモードを使用している場合myconfig.pyは、mycarフォルダーを変更します。

マルチプレイヤーモードを使用している場合myconfig.pyは、各mycarXフォルダーの下で変更します。

Dockerを使用してPCに仮想Donkey Carをインストールする方法

参考：https://medium.com/robocar-store/how-to-install-a-virtual-donkey-car-on-your-pc-using-docker-9e4e4fcf718a

バックグラウンド

Pythonの専門知識のレベルによっては、PCで実行するようにDonkeyCarソフトウェアを設定するのは難しい作業になる可能性があります。また、使用しているプラ​​ットフォームによっても異なります。Windowsユーザーは、より多くの問題に遭遇する傾向があります。あなたが教師の場合、Donkey Carソフトウェアの実行に成功せずに、生徒がCondaまたはPythonを適切にセットアップする方法を理解するのに1時間を費やしたくないでしょう。

ソフトウェアをインストールしなくても、どうすればDonkey Carを試してみることができるのでしょうか。モバイルアプリをダウンロードしてからシミュレーターに接続し、一緒にレースをすることができたらどうでしょうか。それは可能ですか？

Donkey Carソフトウェアをコンテナ化することで、両方の問題を解決できることがわかりました。さらに良いことに、1つのホストで複数の仮想ロバカーコンテナを実行し、同じシミュレータに接続して、直接対戦することができます。

インストール

Dockerをインストールする

• Docker
• Docker-compose

DockerホストにDockerをインストールする必要があります。次の手順に従って、Windows 10 Home、Mac、およびLinuxにDockerをインストールします。比較的古いWindows10 HomeをDockerホストとして使用している場合、Win 10バージョン1903以降が必要になるため、Dockerのインストールにはかなり長い時間がかかることに注意してください。

リポジトリをチェックアウトする

git clone https://github.com/sctse999/donkeycar-docker

翌日再起動

0:事前準備

手順2. 仮想環境のアクティベーション★

手順４. Jupyter Notebookの起動★

4. 学習データの収集

手順2. DonkeySIMの実行★

手順3. DonkeyCarソフトウェアの起動★

上記の順の操作をして、エラーが発生。

これは（手順2. DonkeySIMの実行★）うまくできてないかな？

この日も問題なく操作できました。

通常は、データ収集が終わって、車を止めたい時に、DonkeyCarソフトウェアを止まるしか方法がないようですが、

しかし、数回か、勝手にDonkeyCarソフトウェアが止まったと体験しました。

次は、1000回データ取ったら、勝手に　Shutting down vehicle and its parts…　！なぜでしょう？
