embeddable package版(32bit版)でlightgbmをインストールできない

前提・実現したいこと

Pythonについての質問です。
Pythonの簡易環境であるWindows embeddable package (32-bit)をダウンロードして機械学習を行うプログラムを実装しています。
この環境で「lightgbm」というパッケージを導入したいですが、32ビット環境では、エラーが発生しインストールできませんでした。32bit環境でlightgbmをインストールするにはどうすればよいでしょうか?
また、embeddable package版でcondaを使えるのでしょうか?

発生している問題・エラーメッセージ

は、
例外：32ビットPythonにLightGBMをインストールすることはできません。代わりに64ビットPythonを使用してください。

32bit環境でlightgbmをインストールするにはどうすればよいでしょうか?

の答えはできません、ですね。

回答ありがとうございます。 pythonの別環境であるweb-based installerの32bit版では、condaでlightgbmをインストールできましたが、embeddable版ではできないのですね。仕方がないので、lightgbmの代わりにsklearnをインストールしてプログラムを作成することにします。
