SageMaker Notebook Instance: cannot import name 'get_execution_role' from 'sagemaker'

I am trying to run a pytorch estimator on a local instance. I have a basic script from a SageMaker Studio Notebook which loads the session, region, and role. Because Studio notebooks do not support local instance types, I migrated to Notebook instances. Immediately when I run the first code block, I receive an error.
Environment:

• SageMaker Notebook Instance.
• Kernel: conda_pytorch_p39

import sagemaker
from sagemaker import get_execution_role
from sagemaker.pytorch import PyTorch

# Get the necessary information
sagemaker_session = sagemaker.Session()
role = get_execution_role()

Cannot import name 'get_execution_role' from 'sagemaker' (/home/ec2-user/SageMaker/AI/sagemaker.py)

I also tried the following:

import sagemaker

sagemaker_session = sagemaker.Session()
bucket = sagemaker_session.default_bucket()
role = sagemaker.get_execution_role()

module 'sagemaker' has no attribute 'Session'

I have tried multiple variations of this to no avail. Please help.
