AutoML语言实体提取的score_threshold未被接受为参数

Question

环境详细信息

• 操作系统类型和版本：Windows 10，WSL 2，Ubuntu 16.04
• Python版本：3.7.5
• pip版本：19.3.1
• google-cloud-automl版本：2.2.0

复制步骤

1. 以score_threshold为参数调用AutoML语言实体提取

代码示例

options = ClientOptions(api_endpoint='automl.googleapis.com')
prediction_client = automl_v1.PredictionServiceClient(client_options=options)
payload = {'text_snippet': {'content': 'sample text', 'mime_type': 'text/plain'} }
params = {"score_threshold": "0.04"}
request = prediction_client.predict(name=model_name, payload=payload, params=params)

Answer 1

参数params->score_threshold不可用于AutoML NL实体提取。这仅适用于AutoML视觉分类和AutoML视觉对象检测。请参阅python参考中的predict((。

params(Sequence[~.production_service.PrecdictRequest.ParamsEntry](–

其他特定于域的参数，任何字符串都必须达到25000字符长。

AutoML视觉分类

score_threshold：(float(0.0到1.0之间的值。当模型对图像进行预测，它只会产生至少这个信心得分。默认值为0.5。

AutoML视觉对象检测

score_threshold：(float(当Model检测到图像上的对象时，它只会生成至少具有此置信度的边界框分数值在0到1的范围内，默认值为0.5。

max_bounding_box_count：(int64(边界框的最大数量返回。默认值为100。返回的边界框数可能受到服务器的限制。

但如果使用AutoML NL Classification，则可以使用batch_predict((设置score_threshold。
