Conditions

To make use of the SageMaker Python SDK and run the code related to this submit, you want the next stipulations:

• An AWS account that accommodates your AWS sources
• An AWS Identification and Entry Administration (IAM) position with entry to SageMaker Studio notebooks
• SageMaker JumpStart enabled in a SageMaker Studio area

Create a personal hub, curate fashions, and configure entry management

This part offers a step-by-step information for directors to create a personal hub, curate fashions, and configure entry management on your group’s customers.

1. As a result of the function has been built-in within the newest SageMaker Python SDK, to make use of the mannequin granular entry management function with a personal hub, let’s first replace the SageMaker Python SDK:

   !pip3 set up sagemaker —force-reinstall —quiet

2. Subsequent, import the SageMaker and Boto3 libraries:

   import boto3 from sagemaker
   import Session from sagemaker.session
   import Hub

3. Configure your personal hub:

   HUB_NAME="CompanyHub"
   HUB_DISPLAY_NAME="Allowlisted Fashions"
   HUB_DESCRIPTION="These are allowlisted fashions taken from the SageMaker Public Hub"
   REGION="" # for instance, "us-west-2"

Within the previous code, HUB_NAME specifies the title of your hub. HUB_DISPLAY_NAME is the show title on your hub that shall be proven to customers in UI experiences. HUB_DESCRIPTION is the outline on your hub that shall be proven to customers.

Use an AWS Area the place SageMaker JumpStart is accessible, as of March 2025: us-west-2, us-east-1, us-east-2, eu-west-1, eu-central-1, eu-central-2, eu-north-1, eu-south-2, me-south-1, me-central-1, ap-south-1, ap-south-2, eu-west-3, af-south-1, sa-east-1, ap-east-1, ap-northeast-2, ap-northeast-3, ap-southeast-3, ap-southeast-4, ap-southeast-5, ap-southeast-7, eu-west-2, eu-south-1, ap-northeast-1, us-west-1, ap-southeast-1, ap-southeast-2, ca-central-1, ca-west-1, cn-north-1, cn-northwest-1, il-central-1, mx-central-1, us-gov-east-1, us-gov-west-1.

4. Arrange a Boto3 consumer for SageMaker:

   sm_client = boto3.consumer('sagemaker')
   session = Session(sagemaker_client=sm_client)
   session.get_caller_identity_arn()

5. Verify if the next insurance policies have been already added to your admin IAM position; if not, you’ll be able to add them as inline insurance policies (use the Area configured in Step 3):

   {
       "Model": "2012-10-17",
       "Assertion": [
           {
               "Action": [
                   "s3:ListBucket",
                   "s3:GetObject",
                   "s3:GetObjectTagging"
               ],
               "Useful resource": [
                   "arn:aws:s3:::jumpstart-cache-prod-",
                   "arn:aws:s3:::jumpstart-cache-prod-/*"
               ],
               "Impact": "Enable"
           }
       ]
   }

Along with organising IAM permissions to the admin position, you have to scope down permissions on your customers to allow them to’t entry public contents.

6. Use the next coverage to disclaim entry to the general public hub on your customers. These might be added as inline insurance policies within the person’s IAM position (use the Area configured in Step 3):

   {
       "Model": "2012-10-17",
       "Assertion": [
           {
               "Action": "s3:*",
               "Effect": "Deny",
               "Resource": [
                   "arn:aws:s3:::jumpstart-cache-prod-",
                   "arn:aws:s3:::jumpstart-cache-prod-/*"
               ],
               "Situation": {
                   "StringNotLike": {"s3:prefix": ["*.ipynb", "*/eula.txt"]}
               }
           },
           {
               "Motion": "sagemaker:*",
               "Impact": "Deny",
               "Useful resource": [
                   "arn:aws:sagemaker::aws:hub/SageMakerPublicHub",
                   "arn:aws:sagemaker::aws:hub-content/SageMakerPublicHub/*/*"
               ]
           }
       ]
   }

After you’ve gotten arrange the personal hub configuration and permissions, you’re able to create the personal hub.

7. Use the next code to create the personal hub inside your AWS account within the Area you specified earlier:

   hub = Hub(hub_name=HUB_NAME, sagemaker_session=session)
   
   strive:
     hub.create(
         description=HUB_DESCRIPTION,
         display_name=HUB_DISPLAY_NAME
     )
     print(f"Efficiently created Hub with title {HUB_NAME} in {REGION}")
   besides Exception as e:
     if "ResourceInUse" in str(e):
       print(f"A hub with the title {HUB_NAME} already exists in your account.")
     else:
       increase e

8. Use describe() to confirm the configuration of your hub. After your personal hub is about up, you’ll be able to add a reference to fashions from the SageMaker JumpStart public hub to your personal hub. No mannequin artifacts should be managed by the client. The SageMaker group will handle model or safety updates. For an inventory of obtainable fashions, seek advice from Constructed-in Algorithms with pre-trained Mannequin Desk.
9. To look programmatically, run the next command:

   from sagemaker.jumpstart.filters import Or
   
   filter_value = Or(
   "framework == meta",
   "framework == deepseek"
   )
   fashions = []
   next_token = None
   
   whereas True:
       response = hub.list_sagemaker_public_hub_models(
           filter=filter_value,
           next_token=next_token
       )
       fashions.lengthen(response["hub_content_summaries"])
       next_token = response.get("next_token")
       
       if not next_token:
           break
   print(fashions)

The filter argument is non-obligatory. For an inventory of filters you’ll be able to apply, seek advice from the next GitHub repo.

10. Use the retrieved fashions from the previous command to create mannequin references on your personal hub:

    for mannequin in fashions:
        print(f"Including {mannequin.get('hub_content_name')} to Hub")
        hub.create_model_reference(model_arn=mannequin.get("hub_content_arn"), 
                                   model_name=mannequin.get("hub_content_name"))

The SageMaker JumpStart personal hub presents different helpful options for managing and interacting with the curated fashions. Directors can verify the metadata of a selected mannequin utilizing the hub.describe_model(model_name=) command. To checklist the out there fashions within the personal hub, you should use a easy loop:

response = hub.list_models()
fashions = response["hub_content_summaries"]
whereas response["next_token"]:
    response = hub.list_models(next_token=response["next_token"])
    fashions.lengthen(response["hub_content_summaries"])

for mannequin in fashions:
    print(mannequin.get('HubContentArn'))

If you have to take away a selected mannequin reference from the personal hub, use the next command:

hub.delete_model_reference("")

If you wish to delete the personal hub out of your account and Area, you’ll need to delete all of the HubContents first, then delete the personal hub. Use the next code:

for mannequin in fashions:
    hub.delete_model_reference(model_name=mannequin.get('HubContentName'))
    
hub.delete()

Tremendous-tune fashions referenced within the personal hub
