创建和管理数据集

数据集包含要翻译的内容类型的代表性样本，即源语言和目标语言中的匹配句对。数据集用作训练模型的输入。

构建数据集的主要步骤如下：

创建数据集并确定源语言和目标语言。
导入句对到数据集中。

项目可以有多个数据集，每个数据集用于训练单独的模型。您可以获取可用数据集列表，并且可以删除不再需要的数据集。

创建数据集

要创建自定义模型，首先需要创建一个空数据集，该数据集最终将保存模型的训练数据。创建数据集时，需要确定模型的源语言和目标语言。如需详细了解支持的语言和变体，请参阅自定义模型的语言支持。

网页界面

在 AutoML Translation 界面中，您可以创建新数据集并在同一页面将训练项导入其中。

访问 AutoML Translation 界面。
从标题栏右上角的下拉列表中选择您为其启用了 AutoML Translation 的项目。
在数据集标签页上，点击创建数据集。
在创建数据集对话框中，执行以下操作：
- 输入数据集的名称。
- 从下拉列表中选择源语言和目标语言。选择源语言后，系统就会显示可用的目标语言。
- 点击创建。系统会打开导入标签页。

REST 和命令行

发送创建数据集请求

下面演示了如何向 project.locations.datasets/create 方法发送 POST 请求。本示例针对通过 Cloud SDK 为项目设置的服务帐号使用访问令牌。

在使用任何请求数据之前，请先进行以下替换：

project-id：您的 Google Cloud Platform 项目 ID
dataset-name：新数据集的名称
source-language-code：您要翻译的语言，以 ISO 639-1 代码形式表示，例如“en”
target-language-code：要翻译为的目标语言，如 ISO 639-1 代码，例如“es”

HTTP 方法和网址：

POST https://automl.googleapis.com/v1/projects/project-id/locations/us-central1/datasets

请求 JSON 正文：

{
    "displayName": "dataset-name",
    "translationDatasetMetadata": {
       "sourceLanguageCode": "source-language-code",
       "targetLanguageCode": "target-language-code"
     }
}

如需发送您的请求，请展开以下选项之一：

curl（Linux、macOS 或 Cloud Shell）

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://automl.googleapis.com/v1/projects/project-id/locations/us-central1/datasets"

PowerShell (Windows)

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://automl.googleapis.com/v1/projects/project-id/locations/us-central1/datasets" | Select-Object -Expand Content

您应该收到类似以下内容的 JSON 响应：

{
  "name": "projects/project-number/locations/us-central1/operations/operation-id",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.automl.v1.OperationMetadata",
    "createTime": "2019-10-01T22:13:48.155710Z",
    "updateTime": "2019-10-01T22:13:48.155710Z",
    "createDatasetDetails": {}
  }
}

获取结果

如需获取请求的结果，您必须向 operations 资源发送 GET 请求。下面演示了如何发送此类请求。

在使用任何请求数据之前，请先进行以下替换：

operation-name：在对 API 的原始调用的响应中返回的操作名称

HTTP 方法和网址：

GET https://automl.googleapis.com/v1/operation-name

如需发送您的请求，请展开以下选项之一：

curl（Linux、macOS 或 Cloud Shell）

执行以下命令：

curl -X GET \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
"https://automl.googleapis.com/v1/operation-name"

PowerShell (Windows)

执行以下命令：

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

Invoke-WebRequest `
  -Method GET `
  -Headers $headers `
  -Uri "https://automl.googleapis.com/v1/operation-name" | Select-Object -Expand Content

您应该收到类似以下内容的 JSON 响应：

Python

在运行此代码示例之前，您必须先安装 Python 客户端库。

保存新数据集的全名以用于其他操作（例如，将训练项导入数据集）。

在 GitHub 上查看

from google.cloud import automl

# TODO(developer): Uncomment and set the following variables
# project_id = "YOUR_PROJECT_ID"
# display_name = "YOUR_DATASET_NAME"

client = automl.AutoMlClient()

# A resource that represents Google Cloud Platform location.

created_dataset = response.result()

# Display the dataset information
print("Dataset name: {}".format(created_dataset.name))
print("Dataset id: {}".format(created_dataset.name.split("/")[-1]))

PHP：请按照客户端库页面上的 PHP 设置说明操作，然后访问 PHP 版 AutoML Translation 参考文档。

Ruby：请按照客户端库页面上的 Ruby 设置说明操作，然后访问 Ruby 版 AutoML Translation 参考文档。

将训练项导入数据集

创建数据集后，您可以将训练句对导入其中。如需详细了解如何准备训练数据，请参阅准备训练数据。

网页界面

在 AutoML Translation 界面中，您可以创建新数据集并在同一页面将训练项导入其中（请参阅创建数据集）。要将训练项导入现有数据集，请按以下步骤操作。

创建数据集文件夹之后，您就可以上传数据了。

上传要用于训练模型的句对。

在导入标签页上，您可以从本地计算机或 Cloud Storage 上传 TSV 或 TMX 文件。对于本地导入的文件，请在选择文件后点击浏览。系统会显示文件夹列表。选择您要将文件上传到其中的目标文件夹。为了保证数据驻留，必须在 Cloud Storage 上托管此目录。

如果您要上传包含句对的不同文件，请选中使用不同的文件进行训练、验证和测试（高级）复选框。如果数据集中的句对数超过 100000，则建议使用此选项。您最多只能为验证集和测试集分配 10000 个句对；否则，AutoML Translation 会返回错误。
点击继续。

您会返回到数据集页面。您的数据集会在文档导入期间显示一个进行中动画。成功上传数据集后，我们会向您注册程序时使用的电子邮件地址发送一封邮件。
查看数据集。

成功导入数据后，请从数据集标签页选择相应数据集以查看其详细信息。句子 (Sentence) 标签页已启用，并显示了该数据集的名称。系统会列出句对。每个句对都带有“训练”、“验证”或“测试”标识，指示将使用该句对的处理阶段。

REST 和命令行

使用 projects.locations.datasets.importData 方法将训练项导入数据集。

在使用任何请求数据之前，请先进行以下替换：

dataset_full_id 是数据集的全名，格式为 projects/{project-id}/locations/us-central1/datasets/{dataset-id}
input_uris 的值必须是与此项目关联的 Google Cloud Storage 存储分区中 CSV 文件的路径。格式为 gs://{project-id}-lcm/{document-name}.csv

删除数据集

网页界面

在 AutoML Translation 界面中，点击左侧导航菜单顶部的数据集链接以显示可用数据集的列表。
点击要删除的行最右侧的三点状菜单，然后选择删除。
在确认对话框中点击确认。

REST 和命令行

在创建数据集时，将 dataset-name 替换为数据集的完整名称。全名的格式为 projects/{project-id}/locations/us-central1/datasets/{dataset-id}

在使用任何请求数据之前，请先进行以下替换：

dataset-name：要删除的数据集的名称，格式为 project/project-id/locations/us-central1/datasets/dataset-id

HTTP 方法和网址：

DELETE https://automl.googleapis.com/v1/dataset-name

如需发送您的请求，请展开以下选项之一：

curl（Linux、macOS 或 Cloud Shell）

执行以下命令：

curl -X DELETE \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
"https://automl.googleapis.com/v1/dataset-name"

PowerShell (Windows)

执行以下命令：

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

Invoke-WebRequest `
  -Method DELETE `
  -Headers $headers `
  -Uri "https://automl.googleapis.com/v1/dataset-name" | Select-Object -Expand Content

您应该收到类似以下内容的 JSON 响应：

{
  "name": "projects/project-number/locations/us-central1/operations/operation-id",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.automl.v1.OperationMetadata",

在运行此代码示例之前，您必须先安装 Python 客户端库。

dataset_id 是数据集的全名，格式为 projects/{project-id}/locations/us-central1/datasets/{dataset-id}

# TODO(developer): Uncomment and set the following variables
# project_id = "YOUR_PROJECT_ID"

dataset_full_id = client.dataset_path(project_id, "us-central1", dataset_id)
response = client.delete_dataset(name=dataset_full_id)

print("Dataset deleted. {}".format(response.result()))

导入问题：

创建数据集时，如果句子对过长或源语言和目标语言完全相同，则 AutoML Translation 可能会丢弃这些句对。

对于过长的句对，我们建议将其分解为大约 200 个字或更小的句对，然后重新创建包含已删除句对的数据集。在处理数据时，AutoML Translation 使用内部流程对输入数据进行令牌化，这可能会增加句子的大小。AutoML Translation 可使用此令牌化数据测量数据大小。因此，200 字的上限是最大长度的估算值。

您可以从数据集中移除在源语言和目标语言中相同的句对。如果您希望这些句子保持未翻译状态，请使用术语表资源构建用于定义 AutoML Translation 处理特定术语方式的自定义字典。
