AttributeError：“ ClientCreatorContext”对象没有属性“ invoke_endpoint”

问题描述

我正在尝试使用aioboto3库异步调用SageMaker上的端点。 下面是用于此的简单python代码

import asyncio

import aioboto3


async def entry():
    sagemaker_client = aioboto3.session.Session(profile_name='mlbeta').client('sagemaker-runtime')

    request_body = "...<some-payload>..."

    response = await sagemaker_client.invoke_endpoint(
        EndpointName='ASMSummaryGenerator',Body=request_body,ContentType='application/json'
    )

    response_json = response['Body'].read().decode('utf-8')

    print(response_json)


if __name__ == "__main__":
    loop = asyncio.get_event_loop()
    loop.run_until_complete(entry())

运行此代码时出现以下错误

/Users/rppatwa/anaconda3/bin/python /Volumes/Unix/workplace/RPPythonTestsWS/src/RPPythonTests/src/PythonPlayground/AsyncBoto3SpeakableTest.py
Traceback (most recent call last):
  File "/Volumes/Unix/workplace/RPPythonTestsWS/src/RPPythonTests/src/PythonPlayground/AsyncBoto3SpeakableTest.py",line 43,in <module>
    loop.run_until_complete(entry())
  File "/Users/rppatwa/anaconda3/lib/python3.7/asyncio/base_events.py",line 584,in run_until_complete
    return future.result()
  File "/Volumes/Unix/workplace/RPPythonTestsWS/src/RPPythonTests/src/PythonPlayground/AsyncBoto3SpeakableTest.py",line 30,in entry
    response = await sagemaker_client.invoke_endpoint(
AttributeError: 'ClientCreatorContext' object has no attribute 'invoke_endpoint'
sys:1: RuntimeWarning: coroutine 'AioSession._create_client' was never awaited

aiboto3库是否支持等待invoke_endpoint（）api？如果没有，如何通过其他方式实现异步执行。感谢您的回应。预先感谢！
