Amazon SageMaker notebook instances now support Amazon Linux 2

 Amazon SageMaker notebook instances now support Amazon Linux 2

Today, we’re excited to announce that Amazon SageMaker notebook instances support Amazon Linux 2. You can now choose Amazon Linux 2 for your new SageMaker notebook instance to take advantage of the latest update and support provided by Amazon Linux 2.

SageMaker notebook instances are fully managed Jupyter Notebooks with pre-configured development environments for data science and machine learning. Data scientists and developers can spin up SageMaker Notebooks to interactively explore, visualize and prepare data, and build and deploy models on SageMaker.

Introduced in 2017, Amazon Linux 2 is the next generation of Amazon Linux, a Linux server operating system from AWS first launched in September 2010. Amazon Linux 2 provides a secure, stable, and high-performance runtime environment to develop and run cloud and enterprise applications. With Amazon Linux 2, you get an environment that offers long-term support with access to the latest innovations in the Linux offering. AWS provides long-term security and maintenance updates for the Amazon Linux 2 AMI while the Amazon Linux AMI ended its standard support on December 31, 2020 and has entered a maintenance support phase.

In this post, we show you what your new experience with an Amazon Linux 2 based SageMaker notebook instance looks like. We also share the support plan for Amazon Linux based notebook instances. To learn how to migrate your work from an Amazon Linux based notebook instance to a new Amazon Linux 2 based notebook instance, see our next post Migrate your work to an Amazon SageMaker notebook instance with Amazon Linux 2.

What’s new with Amazon Linux 2 based notebook instances

For a data scientist using SageMaker notebook instances, the major difference is the notebook kernels available in the instance. Because Python 2 has been sunset since January 1, 2020, the kernels with Python 2.x are no longer available in the Amazon Linux 2 based notebook instance. You need to port your code and notebooks from Python 2 to Python 3 before using the same code with python3.x kernels.

Another set of kernels that are no longer provided within the Amazon Linux 2 based instance are Chainer kernels (conda_chainer_p27 and conda_chainer_p36). Chainer has been in a maintenance phase since December 5, 2019, when the last major upgrade to v7 was released. Chainer users are encouraged to follow the migration guide provided by Chainer to port the Chainer code into PyTorch and use the conda_pytorch_p36 or conda_pytorch_latest_p37 in the notebook instance.

SageMaker notebook instances use AMIs that are built on top of the AWS Deep Learning AMI. Therefore, you can find detailed release notes and differences in the AWS Deep Learning AMI (Amazon Linux) and AWS Deep Learning AMI (Amazon Linux 2).
