如何按名称从 SageMaker 功能商店中删除功能组答案

【问题标题】：How to delete Feature Group from SageMaker Feature Store, by name如何按名称从 SageMaker 功能商店中删除功能组
【发布时间】：2021-09-21 23:33:32
【问题描述】：

使用 SageMaker Python SDK 删除特征组的方法如下：

my_feature_group.delete()

但这只会删除您当前正在处理的功能组。如何从以前的会话中删除功能组？我尝试将它们直接从 S3 存储桶中删除，但它们仍然出现在 Feature Store UI 中。

如果可以通过 UI 删除功能组，那就太好了。但如果没有，有没有办法使用全名删除功能组？使用以下方法创建的：

my-feature-group-" + strftime("%d-%H-%M-%S", gmtime())

【解决方案1】：

您可以创建一个FeatureGroup 对象并调用delete 或通过cli 或SageMakerFeatureStoreRuntime 客户端

【解决方案2】：

您可以循环遍历list_feature_groups，如下所示：

def extract_feature_groups(feature_groups):
    list_feature_groups = []
    list_feature_groups.extend([x['FeatureGroupName'] for x in feature_groups['FeatureGroupSummaries']])
    next_token = '' if not ('NextToken' in feature_groups.keys()) else feature_groups['NextToken']
    while not (next_token==''):
        page_feature_groups = boto_client.list_feature_groups(NextToken=next_token)
        list_feature_groups.extend([x['FeatureGroupName'] for x in page_feature_groups['FeatureGroupSummaries']])
        next_token = '' if not ('NextToken' in page_feature_groups.keys()) else page_feature_groups['NextToken']
    return list_feature_groups

region_name = <your_region_name>
boto_client = boto3.client('sagemaker', region_name=region_name)
boto_session = boto3.session.Session(region_name=region_name)
fs_sagemaker_session = sagemaker.Session(boto_session=boto_session)
feature_groups = boto_client.list_feature_groups()
list_features_groups = extract_feature_groups(feature_groups)

for fg in list_features_groups:
            <make sure to include appropriate name filter and/or confirmation requests>
            feature_group = FeatureGroup(name = feature, sagemaker_session = fs_sagemaker_session)
            feature_group.delete()

特征组需要时间来完成删除；您可能想添加一个检查删除是否成功结束的功能。
