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

I work for a large corporation and encountered this same error, but needed a different work around. My issue was related to proxy settings. I had my proxy set up so I needed to set my no_proxy to whitelist AWS before I was able to get everything to work. You can set it in your bash script as well if you don't want to muddy up your Python code with os settings.

Python:

import os
os.environ["NO_PROXY"] = "s3.amazonaws.com"

Bash:

export no_proxy = "s3.amazonaws.com"

Edit: The above assume a US East S3 region. For other regions: use s3.[region].amazonaws.com where region is something like us-east-1 or us-west-2
