Boto3 Error: botocore.exceptions.NoCredentialsError: Unable to locate credentials

Question

When I simply run the following code, I always gets this error.

s3 = boto3.resource(\'s3\')
    bucket_name = \"python-sdk-sample-%s\" % uuid.uuid4()
    pri         


        

Answer 1

If you have multiple aws profiles in ~/.aws/credentials like...

[Profile 1]
aws_access_key_id = *******************
aws_secret_access_key = ******************************************
[Profile 2]
aws_access_key_id = *******************
aws_secret_access_key = ******************************************

Follow two steps:

1. Make one you want to use as a default using export AWS_DEFAULT_PROFILE=Profile 1 command in terminal.

2. Make sure to run above command in the same terminal from where you use boto3 or you open an editor.[Understand the following scenario]

Scenario:

• If you have two terminal open called t1 and t2.
• And you run the export command in t1 and you open JupyterLab or any other from t2, you will get NoCredentialsError: Unable to locate credentials error.

Solution:

• Run the export command in t1 and then open JupyterLab or any other from the same terminal t1.
