    Hello,

    Using the documentation I have done the required configurations in order to run my CPLEX model on the Watson Machine Learning. But when I run it I get the error "The specified key does not exist" or with other endpoints I get "Access denied" 

    Thanks in advance

    Hi,

    While advertised as compatible with Amazon S3, Cloud Object Storage (COS) seems to create difficulties connecting to WML.

    The

    I strongly encourage you to create an Amazon S3 account and use its credentials for storage instead of COS.

    To my knowledge this is working fine with WML.

    Can you please elaborate on how? I created an account on Amazon S3. My guess is that I should use My Security Credentials -> Access Keys and create a new access key. This gives me Access Key and Secret Key. Please correct me if I'm wrong so far. Then what about the endpoint? Should I create my own bucket here?

    The URL and region depends on where you want the data to be stored, here is a list :

    https://docs.aws.amazon.com/general/latest/gr/s3.html

    for example I use

    https://s3-us-west-2.amazonaws.com
    us-west-2


    Access Key and Secret Key can be found in your S3 console : https://console.aws.amazon.com/iam/home#/home

    The bucket (oplide.bucket) will be created automatically.

    I am getting this error: "The bucket is in this region: null" I'm using https://s3.eu-west-2.amazonaws.com and eu-west-2 as the endpoint URL and the region. My WML is based at London. (Base URL: https://eu-gb.ml.cloud.ibm.com)
