Descrevendo um projeto (SDK)

Para descrever um projeto (SDK)

1. Se você ainda não tiver feito isso, instale e configure o AWS CLI e AWS SDKs o. Para obter mais informações, consulte Etapa 4: configurar o AWS CLI e AWS SDKs.

2. Use o código de exemplo a seguir para descrever um projeto. Substitua project_name pelo nome do esquema que deseja descrever. Se não especificar --project-names, as descrições de todos os projetos são retornadas.

   AWS CLI

   aws rekognition describe-projects --project-names project_name \
     --profile custom-labels-access

   Python

   Use o seguinte código: Forneça os seguintes parâmetros de linha de comando:

   • project_name : o nome do projeto que deseja descrever. Se não especificar um nome, as descrições de todos os projetos são retornadas.
