Python NotebookをWebアプリに変換する「mercury」のインストール

Python NotebookをWebアプリに変換する「mercury」のインストールについて解説しています。

「mljar-mercury（https://github.com/mljar/mercury）」は、PythonノートブックをインタラクティブなWebアプリケーションに変換し、他の人と共有することができます。mercuryはデュアルライセンスであり、OSS（オープンソース）ライセンスと、商用ライセンス（プロ）が存在する（https://mljar.com/pricing/）。

■Python

今回のPythonのバージョンは、「3.7.9」を使用しています。（Windows10）（pythonランチャーでの確認）

■mljar-mercuryをインストールする

mljar-mercury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 mljar-mercury

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 3.7.9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 -3.7 -m pip install mljar-mercury

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。
