Python cryptography起因の不具合修正

Pythonに戻る。

概要

　spleeterをインストールすると、cryptographyでBlowfishがalgorithms.Blowfishクラスの複製をしようとされた。みたいな警告が出るようになりました。警告なので無視しておけばいいかなと思いましたが、対策をしました。エラーは以下のようなものです。

…\Anaconda3\lib\site-packages\paramiko\transport.py:219: CryptographyDeprecationWarning: Blowfish has been deprecated
 "class": algorithms.Blowfish,

　

対策

　cryptograpyモジュールを再インストールすると良さそうでした。

(base) … >conda uninstall -y cryptograpy

　としました。conda uninstallのコマンドはあまり有効な手立てになっていないように見えますが、pip install cryptograpy==36.0.2 というコマンドは、既にはいっていた37.0.1を36.0.2にしてくれたみたいです。自分はspleeterをpipコマンドでインストールしたので、このあたりが動作に違いが生じているのかもしれません。conda と pip の違いは複雑です。説明しきれんね。
