Colabの設定¶
（この準備作業は最初に１回行えば大丈夫です）
1. Googleドライブのマウント¶
コンピューターが、ディスクにファイルを書き込んだり読み出したりできるようにすることを「マウントする」と言います。以下のCodeCellを実行すると、GoogleドライブをGoogleColaboにマウントします。
実行の過程で、接続に関する確認が求められるので、許可をして進んでください。
In [1]:
from google.colab import drive
drive.mount('/content/drive', force_remount=True)
Mounted at /content/drive
これで、Colabは、Googleドライブの「マイドライブ」を、ディレクトリ(フォルダ)「/content/drive/MyDrive」として利用できるようになりました。
2. 研修教材の配置¶
まず、カレントディレクトリ(あなたの指示で仕事をしているこのNotebookが仕事場としているディレクトリ)を MyDrive/WXBC に移しておきます。
In [2]:
%cd /content/drive/MyDrive/WXBC
/content/drive/MyDrive/WXBC
次に、以下を実行し、WXBCのホームページから研修教材とサンプルデータをダウンロードしてください。サイズが大変大きいので時間がかかります。失敗する場合もありますので、経過の表示はよく見ておいて下さい。

Colabで取得・展開されたデータは、Googleドライブの画面からも確認できますが、結果が反映されるのにすこし時間がかかりますので、慌てないでください。
ダウンロードしたファイルのサイズは約7GBで、これを展開すると全体では15GB(無料プランの上限)を超過します。このままでは、以降の操作が行えないので、Googleドライブを開いて(既に開いているGoogleドライブに移って)、ファイル challenge3.zip を消去し、さらに、「ゴミ箱を空にする」操作を行ってください。
3. wgrib2のインストール¶
今回インストールするのはバージョン3.7.0です。wgrib2は、バージョン3.6からインストール方法が大幅に変更になり、コンパイルにCmakeを使用するようになりました。ですので、過去に経験のある方も、侮らずに以下をよく読んで作業を進めてください。
3.1 開発ツールの確認¶
wgrib2は、ソースコードをコンパイルすることで作成しますが、コンパイル時のオプションにより、ファイルダンプや補間、画像化、並列処理など様々な機能の有無を設定することができます。そして、設定する機能によっては、そのためのツール(ライブラリ)が必要となることもあります。
この研修において、wigrib2はPythonライブラリwxbcgribxを介して利用されますが、そこで求められる範囲の機能を具備させるためには、NetCDFファイルの入出力を可能にするライブラリー libnetcdf-dev が必要になります。これはaptでインストールすることができます。
確認したところ、Colabにはインストール済みでした。よって、インストール作業は不要であり、wgrib2本体をコンパイルすれば大丈夫です。
参考までに、Colabの仮想マシンにこれが存在しているかどうかは、以下を実行して確認します。
- !apt list --installed | grep libnetcdf-dev
このコンパイルでは、結果として、ツールを何も追加する必要はありませんが、具備させる機能によっては、aptによるインストールや、さらには、今取り組んでいるようなコンパイル作業をツールの準備として実施する必要が生じることもあります。
3.2 wgrib2のコンパイル¶
コンパイルを実行する前に、ホームディレクトリを示す文字列を用意しておきましょう。Colabのホームディレクトリは /root なので以下とします。
In [6]:
HOME = '/root'
では、早速始めましょう。
In [7]:
# ホームディレクトリに移動します。
%cd $HOME
/root
In [ ]:
# このコマンドは、何らかの理由から存在してしまっているものを抹殺するときに使用してください
#!rm -rf $HOME/wgrib2
In [8]:
# wgrib2を取得します
!git clone "https://github.com/NOAA-EMC/wgrib2"

In [9]:
# ソースコードが格納されたディレクトリwgrib2がつくられるのでそこに移動します
%cd wgrib2
/root/wgrib2
必ず実行してください！
ここで、画面左端にあるフォルダの形をしたアイコンをクリックしてリストを表示させ、ファイル /root/wgrib2/CMakeLists.txt を見つけてください。
見つけられたらそれをダブルクリックして開き、20行目を以下のように修正します（off→on）。
option(USE_NETCDF "Use NetCDF" on)
変更したら保存(Ctrl＋S)して閉じてください。
In [10]:
# ディレクトリwgrib2の中に、さらにディレクトリbuildを新規作成し、そこに移動します。
!mkdir build
%cd build
/root/wgrib2/build
In [11]:
# Cmakeをし、続いてmakeします。

3.3 実行ファイルのコピー¶
これでwgrib2の実行ファイルwgrib2 が、/root/wgrib2/build/wgrib2 に出来上がりました。今回作成したwgrib2はこの実行ファイルが一つあれば動作します。
ところで、このファイルは、Colabの仮想マシン上に存在するので、一定の時間がたつと綺麗さっぱり消去されてしまいます。せっかく苦労して作ったのですから、Googleドライブにコピーして、いつまでも使えるようにしておきましょう。
そのために、以下を実行してください。
In [12]:
!mkdir /content/drive/MyDrive/WXBC/wgrib2
!cp /root/wgrib2/build/wgrib2/wgrib2 /content/drive/MyDrive/WXBC/wgrib2/wgrib2
3.4 wxbcbribx.pyの編集¶
wxbcbribx.py はWXBCオリジナルPythonライブラリー wxbcbribx の実体です。 wxbcbribxはGRIBファイルからのデータの取り出しなど簡単に実行できるPythonライブラリーですが、このライブラリ自体にGRIBファイルを操作する機能はなく、wgrib2にそれを任せています。そのため、ライブラリに、wgrib2がインストールされている場所を指定する必要があります。
画面左端にあるフォルダの形をしたアイコンをクリックしてリストを表示させ、ファイル /content/drive/MyDrive/WXBC/challenge3/wxbcgribx.py を見つけてください。
見つけられたらそれをダブルクリックして開き、40行目から42行目までをすべてコメントアウトし、43行目行頭のハッシュ(#)を外してこの行だけを有効します。
変更したら保存して閉じてください。
参考 Pythonライブラリーのインストール¶
GoogleColabには、主だったPythonライブラリーがすでにインストールされていますが、netcdf4 と cartopy については利用者側でインストールする必要があります。できればこれらもGoogleドライブ上にインストールしたいところですが、そうすると、すでにインストールされているライブラリーとの間で不整合が生じてしまうためできません。
ここでは行なわず、仮想マシンを開始するたびに以下を実行します。
!pip install netcdf4
!pip install cartopy
以上で、Google Colaboraty で受講するための準備は終了しました。続いて、環境が正しく構築されているかどうをNotebook setup_test.ipynb で確認してください。この Notebook は、Googleドライブの マイドライブ/WXBC/challenge3 に置かれています。
このNotebookを閉じてから、Googleドライブでマイドライブ/WXBC/challenge3 を開き、setup_test.ipynb にマウスカーソルを乗せて右クリックし、「アプリで実行」＞ 「GoogleColaboratory」を選択して開いてください。
