Describe the bug
When executing the example bell.py, the following error appears:

Thanks for reaching out. This probably has something to do with upgrading boto3 to have the braket client. Please run
pip install boto3 --upgrade
To troubleshoot further, please make sure that you can call get_device in boto3: https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/braket.html#Braket.Client.get_device

Let us know if this has solved your problem.

NicoSchwaller · 2020-08-19T19:48:44Z

Thank you for the answer.
I upgraded boto3 and this did not solve the problem, I have the same error when I call the get_device() method.
My version of boto3 is 1.14.46.

avawang1 · 2020-08-19T21:44:55Z

Thanks @jmp-aws, I'm still unable to reproduce the error. I think it's due to the AWS CLI not being up to date, because the get_device API isn't able to be called.

Another option is to uninstall and re-install boto3.

Or, to start from a new virtualenv and run:
pip install amazon-braket-sdk

Still unable to reproduce the error.

Have you tried running:
aws braket help in the command line and seeing if get-device appears in the list of available commands?
If not, the version of the AWS CLI you have needs to be updated.

@NicoSchwaller does removal of any aws cli models, uninstallation, and re-installation help resolve the issue? These are the commands that solved the issue for myself

brew uninstall awscli
rm -rf ~/.aws/models/aqx
rm -rf ~/.aws/models/braket
brew install awscli
aws braket help

Yes, this did solve the problem, thanks a lot!
