Estou usando o python 3.12.2 na minha máquina Windows. Estou construindo um site de previsão de carreira usando React e Django. Uso vscode como meu IDE. Eu treino um modelo usando o google collab e ele usa a versão 1.2.2 do scikit-learn. Posso instalar outros pacotes como Django, Djangorestframework, mas não consigo instalar o scikit-learn. Estou instalando tudo em ambiente virtual.

    O motivo do problema encontrado é que a construção do pacote scikit-learn a partir do código-fonte requer o Microsoft Visual C++ 14.0 ou superior. Instalar as ferramentas de construção necessárias é o primeiro passo para corrigir esse problema. Veja como fazer isso:

    1. Instale as ferramentas de compilação do Microsoft C++: link

    2. Atualize o pip e o setuptool.

      pip install --upgrade pip setuptools

    3. Instale o scikit-learn

      pip instalar scikit-learn==1.2.2

  2. A primeira versão que fornece rodas para Python 3.12 é o scikit-learn 1.4.0. Consulte https://pypi.org/project/scikit-learn/1.4.0/#files . Portanto, não use a versão antiga, use uma mais recente. Ou pip install scikit-learn==1.4.2simplesmente pip install scikit-learnpara o mais recente (atualmente 1,5).

    A versão 1.2.2 fornece versões até Python 3.11. Se você quiser usar 1.2.2, use Python mais antigo. Faça downgrade para Python 3.11.

  3. O Scikit learn requer o compilador Microsoft Visual C++, pois inclui extensões C/C++ que precisam ser compiladas.

    Scikit-learn 1.2.2 requer Microsft Visual C++ 14.0 ou superior

    Instalador online do vsc++/16: Instalador online do Visual C++ 16

    Instalador offline: Link do instalador offline

    Execute o comando pip install scikit-learn==1.2.2novamente para reinstalar o scikit-learn.
