在 google AutoML 中创建模型后,我们可以使用提供的 python 代码进行预测。这是代码:
import sys
from google.cloud import automl_v1beta1
from google.cloud.automl_v1beta1.proto import service_pb2
def get_prediction(content, project_id, model_id):
prediction_client = automl_v1beta1.PredictionServiceClient()
name = 'projects/{}/locations/us-central1/models/{}'.format(project_id, model_id)
payload = {'image': {'image_bytes': content }}
params = {}
request = prediction_client.predict(name, payload, params)
return request # waits till request is returned
if __name__ == '__main__':
file_path = sys.argv[1]
project_id = sys.argv[2]
model_id = sys.argv[3]
with open(file_path, 'rb') as ff:
content = ff.read()
print get_prediction(content, project_id, model_id)
我意识到它只会打印得分高于 threshold 的检测结果value = 0.5
。示例输出:
payload {
classification {
score: 0.562688529491
}
display_name: "dog"
}
如何打印分数低于阈值 0.5 的其他检测结果(例如将阈值更改为 0.3)?
