There is no-response with SageMaker Endpoint access from Ubuntu Python3

Hello. Even if I access the Endpoint created with SageMaker from the Python3 (3.10.11) code of Ubuntu (22.04.2) as follows, no response is returned. If I run the same code from Python3(3.9.13) on Mac, the result will be returned without any problem. Its security key settings are also the same, so its AWS services, other than SageMaker, work equally well in both environments. I don't know the reason why there is no reaction only in the case of Ubuntu. There is no error returned. If anyone has any idea, please advise me.

import boto3 import json client = boto3.client('sagemaker-runtime') file_name = 'my_photos.jpg' endPoint = 'my-endpoint' with open(file_name, 'rb') as image: f = image.read() b = bytearray(f) endpoint_response = client.invoke_endpoint( EndpointName=endPoint, Body=b, ContentType='image/jpeg' )

Thanks and Regards,
