Google AutoMl 表：如何使用 JAVA 客户端库在数据集中设置目标列
Google AutoMl Tables: How to set target column in the dataset using JAVA client library
根据我的要求，我需要自动化整个周期：-
- 从数据库中以正确格式将数据作为 CSV 格式。
- 正在将其上传到 google 存储桶
- 在 google AutoML 表中创建数据集
- 正在将我上传的 CSV 从存储桶导入数据集
- 根据创建的数据集训练模型
- 训练后部署模型
我已成功完成第 1 步到第 4 步，并且还完成了第 6 步，但 我在第 5 步中遇到问题，我需要在其中定义目标列我的 CSV 文件.
为了解决这个问题，我查看了 AutoMl 文档，但找不到任何通过它的 (AutoMl Tables) JAVA 客户端库来解决这个问题的方法。这是文档中提供的代码，我们需要 2 个重要参数，它们是 tableSpecId 和 columnSpecId 下面是文档中的代码：-
https://cloud.google.com/automl-tables/docs/train
import com.google.cloud.automl.v1beta1.AutoMlClient;
import com.google.cloud.automl.v1beta1.ColumnSpec;
import com.google.cloud.automl.v1beta1.ColumnSpecName;
import com.google.cloud.automl.v1beta1.LocationName;
import com.google.cloud.automl.v1beta1.Model;
import com.google.cloud.automl.v1beta1.OperationMetadata;
import com.google.cloud.automl.v1beta1.TablesModelMetadata;
import java.io.IOException;
import java.util.concurrent.ExecutionException;
class TablesCreateModel {
public static void main(String[] args)
throws IOException, ExecutionException, InterruptedException {
// TODO(developer): Replace these variables before running the sample.
String projectId = "YOUR_PROJECT_ID";
String datasetId = "YOUR_DATASET_ID";
String tableSpecId = "YOUR_TABLE_SPEC_ID";
String columnSpecId = "YOUR_COLUMN_SPEC_ID";
String displayName = "YOUR_DATASET_NAME";
createModel(projectId, datasetId, tableSpecId, columnSpecId, displayName);
}
// Create a model
static void createModel(
String projectId,
String datasetId,
String tableSpecId,
String columnSpecId,
String displayName)
throws IOException, ExecutionException, InterruptedException {
// Initialize client that will be used to send requests. This client only needs to be created
// once, and can be reused for multiple requests. After completing all of your requests, call
// the "close" method on the client to safely clean up any remaining background resources.
try (AutoMlClient client = AutoMlClient.create()) {
// A resource that represents Google Cloud Platform location.
LocationName projectLocation = LocationName.of(projectId, "us-central1");
// Get the complete path of the column.
ColumnSpecName columnSpecName =
ColumnSpecName.of(projectId, "us-central1", datasetId, tableSpecId, columnSpecId);
// Build the get column spec.
ColumnSpec targetColumnSpec =
ColumnSpec.newBuilder().setName(columnSpecName.toString()).build();
// Set model metadata.
TablesModelMetadata metadata =
TablesModelMetadata.newBuilder()
.setTargetColumnSpec(targetColumnSpec)
.setTrainBudgetMilliNodeHours(24000)
.build();
Model model =
Model.newBuilder()
.setDisplayName(displayName)
.setDatasetId(datasetId)
.setTablesModelMetadata(metadata)
.build();
// Create a model with the model metadata in the region.
OperationFuture<Model, OperationMetadata> future =
client.createModelAsync(projectLocation, model);
// OperationFuture.get() will block until the model is created, which may take several hours.
// You can use OperationFuture.getInitialFuture to get a future representing the initial
// response to the request, which contains information while the operation is in progress.
System.out.format("Training operation name: %s%n", future.getInitialFuture().get().getName());
*System*.out.println("Training started...");
}
}
}
在成功将我的 CSV 导入数据集（第 4 步）后，我能够从这 2 个重要参数中获得 tableSpecId，但我无法获得 columnSpecId 因为它定义了列之间的相关性，而且根据我的理解，它还定义了哪一列是目标列。
在网上做了更多研究后，我发现下面提到的 REST API 发送请求以在数据集中设置目标列
https://automl.clients6.google.com/v1beta1/projects/[projectId]/locations/[Location]/datasets/[DatasetId]?updateMask=tablesDatasetMetadata.targetColumnSpecId&key=[auth stuff]
但我正在使用 SpringBoot，这意味着我正在使用 AutoMl 的 JAVA 客户端库。现在，在 AutoML 的客户端库中，我 无法找到任何可以用来显式发送请求的方法，告诉 Google AutoMl 表该特定列是我的目标列 。我想 python 客户端库中有可用的方法，但 java 中没有。我先谢谢你了。

您可以通过在 TableSpec 上调用 ListColumnSpecs 来获取 columnSpecId：https://googleapis.dev/java/google-cloud-clients/latest/com/google/cloud/automl/v1beta1/AutoMlClient.html#listColumnSpecs-com.google.cloud.automl.v1beta1.ListColumnSpecsRequest-
像这样：
TableSpecName parent = TableSpecName.of("[PROJECT]", "[LOCATION]", "[DATASET]", "[TABLE_SPEC]")
ColumnSpec targetColumnSpec;
for (ColumnSpec element : autoMlClient.listColumnSpecs(parent).iterateAll()) {
if (element.getDisplayName().equals("[MY_TARGET_COLUMN]")) {
targetColumnSpec = element;
break;
