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

try specifying keys manually

    s3 = boto3.resource(s3,
         aws_access_key_id=ACCESS_ID,
         aws_secret_access_key= ACCESS_KEY)

Make sure you dont include your ACCESS_ID and ACCESS_KEY in the code directly for security concerns.
Consider using environment configs and injecting them in the code as suggested by @Tiger_Mike.

For Prod environments consider using rotating access keys:
https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_access-keys.html#Using_RotateAccessKey

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 there must be a profile name [default]. Some official documentation make reference to a profile named [credentials], which did not work for me.

If you are looking for an alternative way, try adding your credentials using
AmazonCLI

from the terminal type:-

aws configure

then fill in your keys and region.
