node.js - Node Google Cloud AutoML PredictionServiceClient 问题

Question

我正在尝试使用 google cloud automl API 来使用它的分类服务，但它返回以下错误:

{ Error: 3 INVALID_ARGUMENT: Request contains an invalid argument.

  details: 'Request contains an invalid argument.',
  metadata:
   Metadata {
     internalRepr: Map { 'grpc-server-stats-bin' => [Array] },
     options: {} } }

我的代码看起来与文档完全一样:

function main(
  projectId = 'YOUR_PROJECT_ID',
  location = 'us-central1',
  modelId = 'YOUR_MODEL_ID',
  content = 'text to predict'
) {


  // Imports the Google Cloud AutoML library
  const {PredictionServiceClient} = require('@google-cloud/automl').v1;

  // Instantiates a client
  const client = new PredictionServiceClient();

  async function predict() {
    // Construct request
    const request = {
      name: client.modelPath(projectId, location, modelId),
      payload: {
        textSnippet: {
          content: content,
          mimeType: 'text/plain', // Types: 'test/plain', 'text/html'
        },
      },
    };

    const [response] = await client.predict(request);

    for (const annotationPayload of response.payload) {
      console.log(`Predicted class name: ${annotationPayload.displayName}`);
      console.log(
        `Predicted class score: ${annotationPayload.classification.score}`
      );
    }
  }

我试图查看他们的文档，但没有找到任何答案。奇怪的是，当我使用作为实体提取的项目的模型 ID 时，它可以完美地工作。

有人可以帮我吗？谢谢!

Answer 1

如果模型 ID 引用了错误的模型或不同的实体，您将收到此错误。我在错误地使用数据集 id(与模型 id 的形式相同)时得到了这个。
