使用 API 创建数据集

要创建机器学习模型，您必须先有一组用于训练的代表性数据。使用 API（或控制台）创建空数据集并将数据导入数据集。导入数据后，您可以进行修改并开始模型训练。

创建数据集

使用以下示例为您的数据创建数据集。

请在下面选择您的数据类型：

图片

为数据集指定的数据集架构取决于要用于训练的数据类型：图片、表格、文本或视频。单个图片数据集可用于多个目标，例如分类或对象检测。

REST 和命令行

在使用任何请求数据之前，请先进行以下替换：

• LOCATION：存储数据集的区域。必须是支持数据集资源的区域。例如 us-central1。
• PROJECT：您的项目 ID 或项目编号。
• DATASET_NAME：数据集的名称。
• PROJECT_NUMBER：您的项目的项目编号（显示在响应中）。

HTTP 方法和网址：

POST https://LOCATION-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets

请求 JSON 正文：

{
  "display_name": "DATASET_NAME",
  "metadata_schema_uri": "gs://google-cloud-aiplatform/schema/dataset/metadata/image_1.0.0.yaml"
}

如需发送请求，请选择以下方式之一：

curl

注意：请确保已将 GOOGLE_APPLICATION_CREDENTIALS 环境变量设置为服务帐号私钥文件的路径。

将请求正文保存在名为 request.json 的文件中，然后执行以下命令：

curl -X POST \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
-H "Content-Type: application/json; charset=utf-8" \
-d @request.json \
"https://LOCATION-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets"

PowerShell

注意：请确保已将 GOOGLE_APPLICATION_CREDENTIALS 环境变量设置为服务帐号私钥文件的路径。

将请求正文保存在名为 request.json 的文件中，然后执行以下命令：

$cred = gcloud auth application-default print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
  -Method POST `
  -Headers $headers `
  -ContentType: "application/json; charset=utf-8" `
  -InFile request.json `
  -Uri "https://LOCATION-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets" | Select-Object -Expand Content

您应该会看到类似如下所示的输出。您可以使用响应中的 OPERATION_ID 来获取操作的状态。

{
  "name": "projects/PROJECT_NUMBER/locations/LOCATION/datasets/DATASET_ID/operations/OPERATION_ID",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.aiplatform.v1.CreateDatasetOperationMetadata",

      "updateTime": "2020-07-07T21:27:35.964882Z"
    }
  }

表格

创建数据集时，您也会将其与数据源关联。创建数据集所需的代码取决于训练数据是位于 Cloud Storage 还是 BigQuery 中。如果数据源位于其他项目中，请确保设置所需权限。

Cloud Storage 或 BigQuery 中的表格训练数据不会导入 Vertex AI。（从本地文件导入时，系统会将其导入到 Cloud Storage 中。）当您使用表格数据创建数据集时，数据会与数据集关联。创建数据集后，您对 Cloud Storage 或 BigQuery 中的数据源所做的更改会纳入使用该数据集训练的模型中。在模型训练开始时，将截取数据集的快照。

使用 Cloud Storage 中的数据创建数据集

REST 和命令行

您可以使用 datasets.create 方法创建数据集。

在使用任何请求数据之前，请先进行以下替换：

• LOCATION：存储数据集的区域。必须是支持数据集资源的区域。例如 us-central1。
• PROJECT：您的项目 ID 或项目编号。
• DATASET_NAME：数据集的显示名。
• METADATA_SCHEMA_URI：目标的架构文件的 URI。
  • 分类：gs://google-cloud-aiplatform/schema/dataset/metadata/tabular_1.0.0.yaml
  • 预测：gs://google-cloud-aiplatform/schema/dataset/metadata/time_series_1.0.0.yaml
  • 回归：gs://google-cloud-aiplatform/schema/dataset/metadata/tabular_1.0.0.yaml
• URI：包含训练数据的 Cloud Storage 存储分区的路径 (URI)。可以有多个路径。每个 URI 的格式如下：

  gs://GCSprojectId/bucketName/fileName
  

• PROJECT_NUMBER：您的项目的项目编号（显示在响应中）。

文本

REST 和命令行

在使用任何请求数据之前，请先进行以下替换：

• LOCATION：存储数据集的区域。必须是支持数据集资源的区域。例如 us-central1。
• PROJECT_ID：您的项目 ID。
• DATASET_NAME：数据集的名称。

HTTP 方法和网址：

POST https://LOCATION-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets

请求 JSON 正文：

{
  "display_name": "DATASET_NAME",
  "metadata_schema_uri": "gs://google-cloud-aiplatform/schema/dataset/metadata/text_1.0.0.yaml"
}

如需发送请求，请选择以下方式之一：

curl

注意：请确保已将 GOOGLE_APPLICATION_CREDENTIALS 环境变量设置为服务帐号私钥文件的路径。

将请求正文保存在名为 request.json 的文件中，然后执行以下命令：

curl -X POST \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
-H "Content-Type: application/json; charset=utf-8" \
-d @request.json \
"https://LOCATION-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets"

PowerShell

注意：请确保已将 GOOGLE_APPLICATION_CREDENTIALS 环境变量设置为服务帐号私钥文件的路径。

将请求正文保存在名为 request.json 的文件中，然后执行以下命令：

$cred = gcloud auth application-default print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
  -Method POST `
  -Headers $headers `

  -InFile request.json `
  -Uri "https://LOCATION-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets" | Select-Object -Expand Content

您应该会看到类似如下所示的输出。您可以使用响应中的 OPERATION_ID 来获取操作的状态。

导入数据

对于图片、文本和视频数据，创建空数据集后，您可以将数据导入数据集。如果您之前使用 Python 版 Vertex AI SDK 创建数据集，则可能在创建数据集时已经导入数据。如果是这样，您可以跳过此部分。

您不应将数据导入表格数据集；数据与数据集关联，但不会导入。

请在下面选择您的数据类型：

图片

在数据导入时，您必须根据模型的目标指定具体的架构。对于图片数据，可以使用以下模型目标：

• 单标签分类：获取图片的单个标签注释。
• 多标签分类：获取图片的多个标签注释。
• 对象检测：获取图片中关键对象的边界框和标签注释。

在下面选择您的目标对应的标签页：

单标签分类

REST 和命令行

在使用任何请求数据之前，请先进行以下替换：

• LOCATION：数据集所在的区域。例如 us-central1。
• PROJECT_ID：您的项目 ID。
• DATASET_ID：数据集的 ID。
• IMPORT_FILE_URI：Cloud Storage 中 CSV 或 JSON 行文件的路径，该文件列出了存储在 Cloud Storage 中用于模型训练的数据项；如需了解导入文件格式和限制，请参阅准备图片数据。

HTTP 方法和网址：

POST https://LOCATION-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID:import

请求 JSON 正文：

{
  "import_configs": [
    {
      "gcs_source": {
        "uris": "IMPORT_FILE_URI"
      },
     "import_schema_uri" : "gs://google-cloud-aiplatform/schema/dataset/ioformat/image_classification_multi_label_io_format_1.0.0.yaml"
    }
  ]
}

如需发送请求，请选择以下方式之一：

curl

注意：请确保已将 GOOGLE_APPLICATION_CREDENTIALS 环境变量设置为服务帐号私钥文件的路径。

将请求正文保存在名为 request.json 的文件中，然后执行以下命令：

curl -X POST \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
-H "Content-Type: application/json; charset=utf-8" \
-d @request.json \
"https://LOCATION-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID:import"

PowerShell

注意：请确保已将 GOOGLE_APPLICATION_CREDENTIALS 环境变量设置为服务帐号私钥文件的路径。

将请求正文保存在名为 request.json 的文件中，然后执行以下命令：

$cred = gcloud auth application-default print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
  -Method POST `

  -Uri "https://LOCATION-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID:import" | Select-Object -Expand Content

您应该会看到类似如下所示的输出。您可以使用响应中的 OPERATION_ID 来获取操作的状态。

表格

Cloud Storage 或 BigQuery 中的表格训练数据不会导入 Vertex AI。（从本地文件导入时，系统会将其导入到 Cloud Storage 中。）当您使用表格数据创建数据集时，数据会与数据集关联。创建数据集后，您对 Cloud Storage 或 BigQuery 中的数据源所做的更改会纳入使用该数据集训练的模型中。在模型训练开始时，将截取数据集的快照。

分类

REST 和命令行

在使用任何请求数据之前，请先进行以下替换：

• LOCATION：要存储数据集的区域。例如 us-central1。
• PROJECT：您的项目 ID 或项目编号。
• DATASET_ID：数据集的 ID。
• IMPORT_FILE_URI：Cloud Storage 中 CSV 或 JSON 行文件的路径，该文件列出了存储在 Cloud Storage 中用于模型训练的数据项；如需了解导入文件格式和限制，请参阅准备视频数据。
• OBJECTIVE：指定模型目标，即“classification”、“object_tracking”或“action recognition”。
• PROJECT_NUMBER：您的项目的项目编号（显示在响应中）。

HTTP 方法和网址：

POST https://LOCATION-aiplatform.googleapis.com/v1/projects/PROJECT/locations/LOCATION/datasets/DATASET_ID:import

请求 JSON 正文：

{
  "import_configs": [
    {
      "gcs_source": {
        "uris": "IMPORT_FILE_URI"
      },
     "import_schema_uri" : "gs://google-cloud-aiplatform/schema/dataset/ioformat/automl_video_OBJECTIVE_io_format_1.0.0.yaml"
    }
  ]
}

如需发送请求，请选择以下方式之一：

curl

注意：请确保已将 GOOGLE_APPLICATION_CREDENTIALS 环境变量设置为服务帐号私钥文件的路径。

将请求正文保存在名为 request.json 的文件中，然后执行以下命令：

curl -X POST \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
-H "Content-Type: application/json; charset=utf-8" \
-d @request.json \
"https://LOCATION-aiplatform.googleapis.com/v1/projects/PROJECT/locations/LOCATION/datasets/DATASET_ID:import"

PowerShell

注意：请确保已将 GOOGLE_APPLICATION_CREDENTIALS 环境变量设置为服务帐号私钥文件的路径。

将请求正文保存在名为 request.json 的文件中，然后执行以下命令：

$cred = gcloud auth application-default print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
  -Method POST `
  -Headers $headers `
  -ContentType: "application/json; charset=utf-8" `
  -InFile request.json `
  -Uri "https://LOCATION-aiplatform.googleapis.com/v1/projects/PROJECT/locations/LOCATION/datasets/DATASET_ID:import" | Select-Object -Expand Content

您应该会看到类似如下所示的输出。您可以使用响应中的 OPERATION_ID 来获取操作的状态。

{
  "name": "projects/PROJECT_NUMBER/locations/LOCATION/datasets/DATASET_ID/operations/OPERATION_ID",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.aiplatform.v1.ImportDataOperationMetadata",

获取操作状态

某些请求会启动需要一些时间才能完成的长时间运行的操作。这些请求会返回操作名称，您可以使用该名称查看操作状态或取消操作。Vertex AI 提供辅助方法来调用长时间运行的操作。如需了解详情，请参阅使用长时间运行的操作。

后续步骤

• 使用 Cloud 控制台为数据集修改或添加标签。
• 使用 Vertex AI API 训练 AutoML 模型
• 使用 Vertex AI API 训练 AutoML Edge 模型（仅限图片和视频）。
