Jupyter NotebookでPython3が使えない問題を解決

More than 3 years have passed since last update.

Jupyter Notebookの新規ファイルでPython3が使えない!

Jupyter Notebookを開いてみると新規ファイル(New File)でPython3が選択肢に出てこなかったので
いくつか記事を調べてみると、ターミナルで 

python3 -m IPython kernelspec install-self

を実行すれば解決したという記事がほとんどだった。
自分の場合はこれだけでは解決しなかったので解決策を示す。

次のコマンドを先に実行すれば解決!

python3 -m pip install ipykernel
python3 -m ipykernel install

を実行してインストールが終わった後に

python3 -m IPython kernelspec install-self

を実行すればJupyter NotebookでPython3が使えるようになった!!
