I get the error Boto3 Error: botocore.exceptions.NoCredentialsError: Unable to locate credentials when trying the following code

s3 = boto3.resource('s3')
bucket_name = "python-sdk-sample-%s" % uuid.uuid4()
print("Creating new bucket with name:", bucket_name)
s3.create_bucket(Bucket=bucket_name)

This is output from boto3.set_stream_logger(‘botocore’, level=’DEBUG’)

I think my settings might be wrong, I saved my credential file in C:\Users\myname\.aws\credentials

I’m not sure how to fix it? Give me some advice.

  1. I also think you are setting wrong, please check:

    1) ~/.aws/credentials file

    [MyProfile1]
aws_access_key_id = yourAccessId
aws_secret_access_key = yourSecretKey

[MyProfile2]
aws_access_key_id = yourAccessId
aws_secret_access_key = yourSecretKey

    2) Python script

    from __future__ import print_function
import boto3
import os

os.environ['AWS_PROFILE'] = "MyProfile1"
os.environ['AWS_DEFAULT_REGION'] = "us-east-1"

ec2 = boto3.client('ec2')

# Retrieves all regions/endpoints that work with EC2
response = ec2.describe_regions()
print('Regions:', response['Regions'])

    Make sure it’s like that, it will work
