How to Create a Notebook?

To create an ML Notebook:

1. Click on + New Notebook
2. Fill in the details shown in the table:

Attribute	Description
Notebook Name	Give your Notebook a unique name.
Description	Describe the notebook's purpose and important details.
Instance Type	Choose the type of ML compute instance to launch the notebook instance.
Volume Size	ML notebook storage volume size in GB.
Datasets Write Access	Select datasets with write access required for the notebook.
Datasets Read Access	Select datasets with read access required for the notebook.
Enable Internet Access	This setting controls whether the notebook instance can access the internet. If you set it to "Disabled", the notebook instance can only access resources inside your VPC, and will not be able to use Amazon SageMaker training and endpoint services unless you set up a NAT Gateway in your VPC.
Glue Sessions	User can select this to enable or disable Glue sessions for the notebook instance
Auto Stop	This option allows you to save on resource costs by providing a stop time value. The auto stop process will be triggered every hour, looking for any ML Notebooks that need to be notified or stopped, and sending an email when one of the following criteria is met.
Shared Libraries	If the notebook has glue session enabled, the user can select shared libraries required for the notebook using this option.

You will receive a notification email when:

• The auto-stop process trigger runs every hour, and the stoppage time is less than 30 minutes.
• The auto-stop process was successfully able to stop the ML Notebook after the stop time.
• The auto-stop process wasn't able to stop the ML notebook due to some fatal errors.

Auto Stop Time: You can set the maximum auto stop time for the ML Notebook to be less than 168 hours (7 days). Once the current time is greater than the stop time, the notebook will be stopped at the next whole hour. You can also modify the stop time with the maximum time set to less than 168 hours (7 days).

Note

• Auto-stop process is scheduled to run every hour on the hour (e.g: 6:00, 7:00, 8:00, 9:00).
• You will receive an email notification only if you are subscribed to alerts. To enable alerts, refer to Alert Preferences.
• When the stoppage time elapses, auto stop process will stop the ML Notebook. You need to manually delete the notebook if intended.
• Stopped Notebooks will still incur costs. Hence, if the notebooks are not needed, delete them.

You can set up or create a new notebook instance and use your IPython notebook to perform model training. You can call Python Sagemaker SDK to create a training job.

Once a training job is created, you can use the S3 model location information to create a model in the Amorphic portal. For accessing the datasets inside the IPython notebooks, you can check the dataset details for the S3 location information. For example, the exhibit above shows the dataset details with the respective dataset S3 location.

For the purpose of creating a Sagemaker model in the notebook, the user can use the ml-temp bucket. Amorphic Notebooks have write access to the ml-temp bucket (for example, s3://cdap-us-west-2-484084523624-develop-ml-temp). Please note that this S3 bucket is almost the same as the dataset S3 path, except for the ml-temp at the end. This ml-temp bucket can be used to create a training job and upload a model tar file. This model file location can then be used to create a model using the "Artifact Location" of Amorphic model (see model creation section).

You can use the S3 location mentioned here to read the files related to the training dataset and save the output Sagemaker model tar file for Amorphic model object creation purposes.

Notebook Details

All the information specified while creating the notebook is displayed in the Details page, including the Notebook URL and Message field. The Message field displays different information based on the notebook's status:

• If the notebook status is failed, the Message field displays the failure information.
• If you do not have all the datasets access required for the notebook, the Notebook URL will not be displayed and the Message field will show the missing datasets access information.

Following details are displayed when you enable auto-stop on the ML Notebook. Remaining Time denotes the amount of time (rounded to nearest upper hour) left for auto-stop.

In below image, the auto stop time is set to 10 July, 2023 7:300 PM but the ML Notebook will be stopped at 10 July, 2023 8:00 PM because the stoppage process is scheduled to run at whole hour (UTC)

Note

Starting from version 1.9, Auto stop will replace Auto terminate. This process will only stop the notebook instance and won't delete the instance.

In the details page, Estimated Cost of the ML notebook is also displayed to show the approximate cost incurred since the creation/last modified time.

Edit Notebook

The Edit Notebook page is divided into two sections:

• Basic Info: You can use this section to update all the basic details of the notebook.
• Instance Info: You can use this section to update instance details like type, size, auto-stop time etc.

Note

The ML Notebook must be in Stopped state in order to edit it.

Start Notebook

When an ML Notebook is in the stopped state (stopped either manually or through auto stop), user has an option to resume or start the Notebook again. The option is available in the UI through a play button beside the Notebook name.

When resuming a stopped ML Notebook, if it was created with Auto Stop and the Auto Stop time has already passed, users will have two options; disable auto stop and resume the ML Notebook, or update the auto stop time with a newer one. The example below shows how it is done.

Stop Notebook

For a running ML Notebook, user is provided with the option to stop it. This feature is useful to reduce incurring costs on running Notebooks. The option is available in the UI through a stop button beside the Notebook name.

Clone Notebook

To help create Notebooks with similar properties, an option to clone an existing Notebook is available. Be sure that the name is different while going through the metadata. The option is available in the UI through a clone button beside the Notebook name.

Delete Notebook

If you have sufficient permissions you can delete an ML Notebook. Deleting an ML Notebook is an asynchronous operation. When triggered, the status will change to deleting and the notebook will be deleted from AWS Sagemaker. Once the notebook is deleted in AWS Sagemaker, the associated metadata will also be removed.

Note

The ML Notebook must be in Stopped state in order to delete it.

Notebook Logs

Logs are now available for Notebooks to be downloaded. There can be one or three types of logs available, depending on the type of Notebook being used.

For glue-session enabled notebooks, there are three types of logs, Creation Logs, Start Logs and Jupyter Logs. For glue-session disabled notebooks, there is just one type of log, Jupyter Logs.

The following example shows how to access the creation logs for a glue-session enabled Notebook.

Update Resources

Users can provide parameters, datasets, and shared libraries access to notebook using the 'Update Resources' option from the three dots button on the top right side of the details page.

Update Extra Resource Access

To provide parameter or dataset access to a notebook in large numbers, use the documentation on How to provide large number of resources access to an ETL Entity in Amorphic

Manage External Libraries

Users can upload external libraries to notebooks with glue session enabled using the 'Manage External Libraries' option from the three dots on the top right side of the details page. Click the '+' sign on the top right & then Click on 'Select files to upload' and then 'Upload Selected Files' button after selecting the files to upload one or more library file(s). Users can upload .zip, .py, and .jar files to the notebook.

The following example shows how to upload external libraries to glue-session enabled Notebook.

Users can remove the external libraries from the Notebook by selecting the libraries and clicking on the 'Remove selected libraries' button in 'Manage External Libraries'. User can also download the external libraries by clicking on the download button displayed on the right of each uploaded library path.

Glue Session Operations

Amorphic ML Notebook provides the below operations for a glue sessions enabled notebook.

Operation	Description
Create Glue Session	Create a Glue session for a Notebook.
Stop Glue Session	Stop an existing Glue session for ML Notebook.
Delete Glue Session	Delete an existing Glue session for ML Notebook.
View & Download Logs for Glue Session	View and download logs of a Glue session for ML Notebook.

Before initiating a Glue session, users have the ability to configure spark settings using imperative magic commands provided by AWS. Below are some beneficial magic commands provided for user reference. For more information visit the link

Magic Command	Type	Description
%number_of_workers	int	The number of workers of a defined worker_type that are allocated when a job runs. worker_type must be set too. The default number_of_workers is 5.
%worker_type	int	Standard, G.1X, or G.2X. number_of_workers must be set too. The default worker_type is G.1X.
%iam_role	String	Specify an IAM role ARN to execute your session with. Default from ~/.aws/configure
%additional_python_modules	List	Comma separated list of additional Python modules to include in your cluster (can be from PyPI or S3).
%extra_py_files	List	Comma separated list of additional Python files from Amazon S3.
%extra_jars	List	Comma-separated list of additional jars to include in the cluster.

Create Glue Session

The user must create a notebook instance with Glue Session enabled as described in the steps for creating a notebook.

Once the notebook instance is active ( if the notebook status is stopped, the user must start the notebook), the user can find the Notebook URL on the details page and on opening the Notebook URL the user is redirected to the Jupyter server. The user has to create a new Jupyter notebook with conda_glue_pyspark kernel.

If the user wants to import external libraries or shared libraries into the notebook, use the below Jupyter magics before starting a glue session:

• %extra_py_files followed by comma separated list of s3 locations for python files.
• %extra_jars followed by comma separated list of s3 locations for jar files.

Users can copy the S3 locations from the notebook details page and ETL libraries page for external and shared libraries respectively. An example for adding extra python library to the session is shown below.

%extra_py_files s3://etl-bucket/notebook-id/libs/amorphicutils.zip

The following code example will help the user create a glue session for the notebook.

import sys
from awsglue.transforms import *
from awsglue.utils import getResolvedOptions
from pyspark.context import SparkContext
from awsglue.context import GlueContext
from awsglue.job import Job

glueContext = GlueContext(SparkContext.getOrCreate())

With glue sessions enabled, notebooks offer the capability to execute SQL commands using Magic commands

%%sql
select * from table

Once the glue session is created, all active and stopped sessions of the notebook can be viewed in the sessions tab of the notebook details page.

Stop Glue Session

Delete Glue Session

Note

If a notebook with glue sessions enabled is stopped, all the glue sessions associated with the notebook will be deleted.

Notebook use case

A use case for ML Notebook could be a company that wants to use machine learning to predict customer churn.

The company can set up a new notebook instance on the Amorphic platform and use IPython notebooks to perform model training. They can call the Python Sagemaker SDK to create a training job using the customer churn data stored in the S3 bucket.

Once the training job is complete, the company can use the S3 model location information to create a model in the Amorphic portal. They can access the customer churn dataset inside the IPython notebooks using the dataset details and S3 location information. The ml-temp bucket can be used to create the Sagemaker model and upload the model tar file, which can then be used to create a model object in the Amorphic portal.

The company can use the S3 location mentioned in the use case to read the files related to the customer churn dataset and save the output Sagemaker model tar file for Amorphic model object creation. This allows the company to effectively train a machine learning model to predict customer churn and use it in their business processes.
