查看您的数据集
一个项目可以有单个数据集,用于训练和测试模型。或者,您可以使用单独的训练数据集和测试数据集。您可以使用控制台查看自己的数据集。您还可以使用 DescribeDataset
操作来获取与数据集(训练或测试)有关的信息。
查看项目中的数据集(控制台)
执行以下过程中的步骤,可以在控制台中查看项目的数据集。
查看项目中的数据集 (SDK)
您可以使用 DescribeDataset
操作,获取与项目关联的训练或测试数据集的信息。

安装并配置 AWS CLI 和 AWS SDK(如果尚未如此)。有关更多信息,请参阅 第 4 步:设置 AWS CLI 以及 AWS SDKs。
使用以下示例代码查看数据集。
- CLI
-
更改以下值:
aws lookoutvision describe-dataset --project-name project name
\
--dataset-type train or test
\
--profile lookoutvision-access
