 ### Notes
 
 * Since SageMaker Studio overrides `ENTRYPOINT` and `CMD` instructions (see [documentation](https://docs.aws.amazon.com/sagemaker/latest/dg/studio-byoi-specs.html)), this sample disables the Poetry virtual environments as recommended in their [FAQ](https://python-poetry.org/docs/faq/#i-dont-want-poetry-to-manage-my-virtual-environments-can-i-disable-it). 
-* Note that `ipykernel` must be installed on custom images for SageMaker Studio. If this package is not installed by default on the parent image, then it should be included in the `pyproject.toml` file.
