rembgをインストールを行いますが、今回はpipを経由してインストールを行うので、まずWindowsのコマンドプロンプトを起動します。

pip install rembg

起動後、上記のコマンドを入力し、Enterキーを押します。

なお、今回は、pythonランチャーを使用しており、Python Version 3.8.5にインストールを行うために、バージョンの切り替えを行います。

py -3.8 -m pip install rembg

切り替えるために、上記のコマンドを入力し、Enterキーを押します。

Enterキーを押すと、インストールが開始され、上記のように「Successfully installed」と表示されます。これが表示されれば、rembgが正常にインストールされたことになりますが、「WARNING」と表示されました。「WARNING」はエラーではなく警告で、インストールは行われているので、今回は一旦無視しています。

なお、今回はrembgのバージョン2.0.49をインストールしました。
