専用の仮想環境を作成
Anacondaの環境にscikit-learnの環境を構築します。
まず「scikit-learn」専用の仮想環境を作りましょう。
左メニューの[Environments]を選択します。
仮想環境一覧の下の[Create]をクリックします。
仮想環境の名前を入力して[Create]をクリックします。
仮想環境が作成されます。
作ったばかりの環境にはこれしかインストールされているものがありません。
scikit-learnをインストール
それではさっそくscikit-learnをインストールしてみます。
▶️ボタンをクリックしてクリックして[Open Terminal]でターミナルを起動します。
Anaconda環境へのインストールには、conda コマンドを使います。以下のコマンドを入力しましょう。
$ conda install scikit-learn
以下のモジュールがインストールされます。

まとめ
解説するまでもなかったのですが、以上で Anaconda 環境へのscikit-learn のインストールの完了です。
ついでにJupyter Notebookもインストールしました。
次回は実際に scikit-learn を使ってみたいと思います。
