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    Make one you want to use as a default using export AWS DEFAULT PROFILE Profile 1 command in terminal  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

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

I had the same issue and found out that the format of my    aws credentials file was wrong   It worked with a file containing    default  aws access key id XXXXXXXXXXXXXX aws secret access key YYYYYYYYYYYYYYYYYYYYYYYYYYY   Note that the profile name must be   default    Some official documentation make reference to a profile named   credentials    which did not work for me
