AWS sagemaker错误-AttributeError：“NoneType”对象没有属性“startswith”

Question

根据此 - How to use a pretrained model from s3 to Predict some data? ，我试图使用现有模型来创建端点，但我遇到了以下错误 -

    Traceback (most recent call last):
  File "/miniconda3/lib/python3.7/site-packages/gunicorn/workers/base_async.py", line 55, in handle
    self.handle_request(listener_name, req, client, addr)

根据问题部署使用 sagemaker.estimator.Estimator (w/sklearn custom image) 获得的最佳估计器，https://forums.aws.amazon.com/thread.jspa ?threadID=313838 ，我正在使用正确的环境变量（以及SAGEMAKER_DEFAULT_INVOCATIONS_ACCEPT、SAGEMAKER_PROGRAM和SAGEMAKER_SUBMIT_DIRECTORY），但不知何故，在创建端点时运行状况检查失败。

我通过 AWS 控制台尝试了类似的操作，效果令人惊讶。有没有办法通过代码来完成此操作？

我的代码片段：

trainedmodel = sagemaker.model.Model(
model_data='s3://my-bucket/my-key/output/model.tar.gz',
image='my-image',
env={"SAGEMAKER_DEFAULT_INVOCATIONS_ACCEPT": "text/csv", 
     "SAGEMAKER_USE_NGINX": "True", 
     "SAGEMAKER_WORKER_CLASS_TYPE": "gevent", 
     "SAGEMAKER_KEEP_ALIVE_SEC": "60", 
     "SAGEMAKER_CONTAINER_LOG_LEVEL": "20",
     "SAGEMAKER_ENABLE_CLOUDWATCH_METRICS": "false",
     "SAGEMAKER_PROGRAM": "my-script.py",
     "SAGEMAKER_REGION": "us-east-1",
     "SAGEMAKER_SUBMIT_DIRECTORY": "s3://my-bucket/my-key/source/sourcedir.tar.gz"
    },
role=role)

trainedmodel.deploy(initial_instance_count=1, instance_type='ml.c4.xlarge', endpoint_name = 'my-endpoint')

对于登陆这里的其他人来说，我在从 ModelPackage 创建 sklearn 模型时遇到了类似的问题。

尝试创建端点时端点日志中出现错误消息：

AttributeError：“NoneType”对象没有属性“startswith”

定义模型包时解决了以下问题：

• 环境变量SAGEMAKER_SUBMIT_DIRECTORY通常应设置为容器上的目录'/opt/ml/model/'
• SAGEMAKER_PROGRAM应设置为服务脚本的名称，例如“sagemaker_serve.py”

这些在“容器”部分中每个条目的“环境”部分下指定。
