【備忘録】PyInstallerでexe化したときにハマった話

pyinstallerを使ってexe化したら以下のようなエラーがでた。

PyInstallerとscikit-learnの問題かと思い、scikit-learnのバージョンを1.1.2 > 1.0.1 に変えてみたけど治らず。

モジュールの相性かも知れないと思ったのでpip listで一覧を見てみたら
115もあったので特定ができない。

PS C:\Users\user\Desktop\chino> (pip list | Measure-Object).Count
115

なので大人しくvenvの環境立てて必要なpip installしていったらうまく行った。
