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

Question

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.

Accepted Answer

You seem to have a `sagemaker.py` in your working directory that the cell is importing. `get_execution_role`, `session` etc. are part of the sagemaker python SDK (https://sagemaker.readthedocs.io/en/stable/overview.html).

Not sure why you have the `sagemaker.py` file, if it's a helper function, try renaming it and trying the cell again. SageMaker notebooks should have sagemaker already installed, you can also install/upgrade it using pip.
