停止您的亞馬遜 Lookout for Vision 模型
要停止正在運行的模型，請調用StopModel操作並傳遞以下內容：
Amazon 觀察視覺主控台提供可用於停止模型的範例程式碼。
停止您的模型（控制台）
執行下列程序中的步驟，使用控制台停止模型。
若要停止您的模型 (主控台)
-
如果您尚未這樣做，請安裝並設定AWS CLI和 AWS SDK。如需詳細資訊，請參閱步驟 4：設定 AWS CLI 和 AWS 軟體開發套件。
打開亞馬遜 Lookout for Vision 控制台 https://console.aws.amazon.com/lookoutvision/.
選擇 Get started (開始使用)。
在左側導覽窗格中，選擇 [專案]。
在 [專案資源] 頁面上，選擇包含您要停止的執行中模型的專案。
在「模型」區段中，選擇您要停止的模型。
在模型的詳細資料頁面上，選擇 [使用模型]，然後選擇 [將 API 整合至雲端]。
在 AWS CLI 命令下，複製呼叫的 AWS CLI 命令stop-model。
-
於指令提示下，輸入您在上一個步驟中複製的stop-model指令。如果您使用lookoutvision設定檔取得認證，請新增--profile
lookoutvision-access參數。
在主控台中，選擇左側導覽頁面中的 [模型]。
檢查「狀態」(Status) 欄以瞭解模型的目前狀態。當「狀態」欄值為「訓練完成」時，模型已停止。
停止您的亞馬遜 Lookout for Vision 模型（SDK）
您可以呼叫StopModel作業來停止模型。
模型可能需要一段時間才能停止。若要檢查目前狀態，請使用DescribeModel。
若要停止您的模型 (SDK)
-
如果您尚未這樣做，請安裝並設定AWS CLI和 AWS SDK。如需詳細資訊，請參閱步驟 4：設定 AWS CLI 和 AWS 軟體開發套件。
使用下列範例程式碼來停止執行中的模型。
- CLI
-
變更下列值：
aws lookoutvision stop-model --project-name "project name"\
--model-version model version \
--profile lookoutvision-access
- Python
