Fix NoCredentialsError

✅ Solution

The "NoCredentialsError" in mlflow typically arises when your program doesn't have the necessary AWS credentials to access S3 or other cloud storage used for artifact logging. To fix it, explicitly configure AWS credentials by setting the AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, and AWS_REGION environment variables, or by configuring an IAM role if running in an AWS environment like EC2 or EKS. Alternatively, configure a default AWS profile using the AWS CLI.
