Pythonで作られたpandas DataFrameから時系列データを視覚化するツール「vpselector」のインストールについて解説しています。
「vpselector（https://github.com/manumerous/vpselector）」は、pandas データフレームから数値時系列データの一部を視覚的に選択するPythonを用いて作られたツールです。
■Python
今回のPythonのバージョンは、「3.10.9」を使用しています。（Windows11）（pythonランチャーでの確認）
■vpselectorをインストールする
vpselector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 vpselector
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 3.10.9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 -3.10 -m pip install vpselector
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、vpselector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vpselectorのバージョン1.0.2をインストールしました。
