问题 I'm new to using AWS EBS and ECS, so please bear with me if I ask questions that might be obvious for others. To the issue: I've got a single-container Node/Express application that runs on EBS. The local docker container works as expected. On EBS, I can access one endpoint of the API and get the expected output. For the second endpoint, which runs longer (around 10-15 seconds) I get no response and run after 60 seconds into a time out: "504 Gateway Time-out". I wonder how I would approach

问题 I have a pre-trained Tensorflow model, I'm trying to using SagaMaker client.create_endpoint() to create an endpoint so that I can call the API to get predictions, the doc is here After creating the model by using client.create_model() I have a model stored on SageMaker, and the base image I'm using is 763104351884.dkr.ecr.us-east-1.amazonaws.com/tensorflow-inference:1.15.2-gpu , this is my code: model_name = `xxx`, role = `xxx`, model_base_image = `763104351884.dkr.ecr.us-east-1.amazonaws.com

问题 Below is the schema for the athena table I wish to calculate median for 'parameter_value' group by standard_lab_parameter_name & units. For this I followed link : https://docs.aws.amazon.com/redshift/latest/dg/r_MEDIAN.html But on running the query select median(parameter_value) from table_name group by standard_lab_parameter_name, units It throws error SYNTAX_ERROR: line 1:8: Function median not registered Any help? Or if some alternative query would be great 回答1: Athena is based on Presto 0

问题 this is my problem: I have to run a Sagemaker processing job using custom code written in PySpark. I've used the Sagemaker SDK by running these commands: spark_processor = sagemaker.spark.processing.PySparkProcessor( base_job_name="spark-preprocessor", framework_version="2.4", role=role_arn, instance_count=2, instance_type="ml.m5.xlarge", max_runtime_in_seconds=1800, ) spark_processor.run( submit_app="processing.py", arguments=['s3_input_bucket', bucket_name, 's3_input_file_path', file_path ]

问题 The use case: I have a bid table which holds the bid on Loades. One Load can have multiple Bids. The Bid status is new for every bid. Once the bid is accepted by the Admin(The person who put that Load up for bidding) then I need to change the status for that particular bid as "Accepted" and for other bids on the same Load the status should be "rejected". Table Definition: Bid_id(Which is unique for every record) and Load_id(multiple entries) is my primary and sort key respectively. How do I

问题 I'm looking at AWS Cognito documentaion here Authentication with a User Pool Actually I looked at many links in the documentation without finding clear information about this.

But I want to do that directly from REST client, for testing purposes to generate user tokens. I want to submit the required credentials, username and password and

问题 I am trying to pass a list of values from a aws cli query to another command. Even though I have seen plenty of examples in AWS, when I try all the values come together: policy_versions=`aws iam list-policy-versions --query "Versions[].VersionId" --policy-arn $POLICY_ARN --output text` echo "policy_versions=$policy_versions" for ver in $policy_versions; do echo "first version: $ver" done Which then prints out: policy_versions=v3 v2 v1 first version: v3 v2 v1 My value of ver is the entire
