This method permits for higher flexibility and integration with current AI/ML workflows and pipelines. By offering a number of entry factors, SageMaker JumpStart helps you seamlessly incorporate pre-trained fashions into your AI/ML improvement efforts, no matter your most well-liked interface or workflow.

Deploy Meta SAM 2.1 for inference utilizing SageMaker JumpStart

On the SageMaker JumpStart touchdown web page, you’ll be able to uncover the general public pre-trained fashions provided by SageMaker AI. You possibly can select the Meta mannequin supplier tab to find the Meta fashions obtainable.

Should you’re utilizing SageMaker Studio and don’t see the SAM 2.1 fashions, replace your SageMaker Studio model by shutting down and restarting. For extra details about model updates, discuss with Shut down and Replace Studio Traditional Apps.

You possibly can select the mannequin card to view particulars in regards to the mannequin equivalent to license, knowledge used to coach, and the right way to use. You can too discover two buttons, Deploy and Open Pocket book, which allow you to use the mannequin.

While you select Deploy, you have to be prompted to the following display to decide on an endpoint title and occasion kind to provoke deployment.

Upon defining your endpoint settings, you’ll be able to proceed to the following step to make use of the mannequin.

Deploy Meta SAM 2.1 imaginative and prescient segmentation mannequin for inference utilizing the Python SDK

While you select Deploy, mannequin deployment will begin. Alternatively, you’ll be able to deploy by the instance pocket book by selecting Open Pocket book. The pocket book gives end-to-end steerage on the right way to deploy the mannequin for inference and clear up assets.

To deploy utilizing a pocket book, you begin by deciding on an acceptable mannequin, specified by the model_id. You possibly can deploy any of the chosen fashions on SageMaker AI.

You possibly can deploy a Meta SAM 2.1 imaginative and prescient segmentation mannequin utilizing SageMaker JumpStart with the next SageMaker Python SDK code:

from sagemaker.jumpstart.mannequin import JumpStartModel 
mannequin = JumpStartModel(model_id = "meta-vs-sam-2-1-hiera-tiny") 
predictor = mannequin.deploy()

This deploys the mannequin on SageMaker AI with default configurations, together with default occasion kind and default VPC configurations. You possibly can change these configurations by specifying non-default values in JumpStartModel. After it’s deployed, you’ll be able to run inference in opposition to the deployed endpoint by the SageMaker predictor. There are three duties which can be obtainable with this endpoint: automated masks generator, picture predictor, and video predictor. We offer a code snippet for every later on this submit. To make use of the predictor, a sure payload schema must be adopted. The endpoint has sticky classes enabled, so to begin inference, it’s good to ship a start_session payload:

def start_session(asset_type, asset_path):

    asset_base64 = None
    
     with open(image_path, 'rb') as f:
            asset_base64 = base64.b64encode(f.learn()).decode('utf-8')
    
    response = predictor.invoke_endpoint(
        EndpointName=endpoint_name,
        ContentType="software/json",
        Physique=json.dumps({
                    "kind": "start_session",
                    "input_type": asset_type,
                    "path": asset_base64 
                }),
        SessionId="NEW_SESSION",
    )
    
    session_id = response.headers.get("x-amzn-sagemaker-new-session-id")
    
    return session_id

The start_session invocation wants an enter media kind of both picture or video and the base64 encoded knowledge of the media. This can launch a session with an occasion of the mannequin and cargo the media to be segmented.

To shut a session, ship a close_session invocation:

def close_session(session_id):
    response = predictor.invoke_endpoint(
        EndpointName=endpoint_name,
        ContentType="software/json",
        Physique=json.dumps({
                    "kind": "close_session",
                    "session_id": session_id
                }),
        SessionId=session_id,
    )
    
    session_id = response.headers.get("x-amzn-sagemaker-closed-session-id")
    
    return session_id

If x-amzn-sagemaker-closed-session-id exists as a header, then the session has been efficiently closed.

To proceed a session and retrieve the session ID of the present session, the response header can have the x-amzn-sagemaker-session-id key with the present session ID for any operation that isn’t start_session or close_session. Operations that aren’t start_session or close_session must be invoked with a response stream. That is as a result of dimension of the ensuing payload being bigger than what SageMaker real-time endpoints can return.

This can be a primary instance of interacting with the SAM 2.1 SageMaker JumpStart endpoint with sticky classes. The next examples for every of the duties reference these operations with out repeating them. The returned knowledge is of mime kind JSONL. For extra full examples, discuss with the instance notebooks for Meta SAM 2.1 on SageMaker Jumpstart.

Really useful situations and benchmarks

The next desk lists all of the Meta SAM 2.1 fashions obtainable in SageMaker JumpStart together with the model_id, default occasion varieties, and most variety of complete tokens (sum of variety of enter tokens and variety of generated tokens) supported for every of those fashions. For elevated context size, you’ll be able to modify the default occasion kind within the SageMaker JumpStart UI.

Meta SAM 2.1 use instances: Inference and immediate examples

After you deploy the mannequin utilizing SageMaker JumpStart, it’s best to be capable to see a reference Jupyter pocket book that references the parser and helper features wanted to start utilizing Meta SAM 2.1. After you comply with these cells within the pocket book, you have to be prepared to start utilizing the mannequin’s imaginative and prescient segmentation capabilities.

Meta SAM 2.1 affords assist for 3 completely different duties (automated masks generator, picture predictor, video predictor) to generate masks for numerous objects in photographs, together with object monitoring in movies. Within the following examples, we reveal the right way to use the automated masks generator and picture predictor on a JPG of a truck. This truck.jpg file is saved within the jumpstart-cache-prod bucket; you’ll be able to entry it with the next code:

s3_bucket = f"jumpstart-cache-prod-{area}"
key_prefix = "inference-notebook-assets"

def download_from_s3(key_filenames):
    for key_filename in key_filenames:
        s3.download_file(s3_bucket, f"{key_prefix}/{key_filename}", key_filename)
        
truck_jpg = "truck.jpg"

#Obtain photographs.
download_from_s3(key_filenames=[truck_jpg])
show(Picture(filename=truck_jpg))

After you’ve gotten your picture and it’s encoded, you’ll be able to create masks for objects within the picture. To be used instances the place you wish to generate masks for each object within the picture, you should use the automated masks generator process.

Automated masks generator

The automated masks generator is nice for AI researchers for laptop imaginative and prescient duties and functions equivalent to medical imaging and diagnostics to routinely section areas of curiosity like tumors or particular organs to supply extra correct diagnostic assist. Moreover, the automated masks generator might be notably helpful within the autonomous car area, during which it might section out components in a digicam like pedestrians, autos, and different objects. Let’s use the automated masks generator to generate masks for all of the objects in truck.jpg.

The next code is the immediate to generate masks on your base64 encoded picture:

# Begin session
session_id = start_session("picture", truck_jpg)
    
# Generate and visualize masks with primary parameters
response = runtime_client.invoke_endpoint_with_response_stream(
        EndpointName=endpoint_name,
        ContentType="software/json",
        Physique=json.dumps({
            "kind": "generate_automatic_masks",
            "session_id": session_id,
            "points_per_side": 32,
            "min_mask_region_area": 100
        }),
        SessionId=session_id,
        Settle for="software/jsonlines"
    )
    
# Parse response stream
parser = StreamParser()
for occasion in response['Body']:
    parser.write(occasion)

masks = parser.get_responses()

# Finish session
end_session(session_id)

We obtain the next output (parsed and visualized).

Picture predictor

Moreover, you’ll be able to select which objects within the offered picture you wish to create a masks for by including factors inside that object for Meta SAM 2.1 to create. A use case for the picture predictor might be invaluable for duties associated to design and modeling by automating processes that usually require guide efforts. For instance, the picture predictor can automate turning 2D photographs into 3D fashions by analyzing 2D photographs of blueprints, sketches, or flooring plans and producing preliminary 3D fashions. That is one among many examples of how the picture predictor can act as a bridge between 2D and 3D development throughout many alternative duties. We use the next picture with the factors that we used to immediate Meta SAM 2.1 for masking the article.

The next code is used to immediate Meta SAM 2.1 and plot the coordinates:

# Begin session
session_id = start_session("picture", truck_jpg)

factors = [
            {"type": "point", "coordinates": [500, 375], "label": 1},
            {"kind": "level", "coordinates": [1125, 625], "label": 1}
         ]
    
# Add a number of factors
response = runtime_client.invoke_endpoint_with_response_stream(
        EndpointName=endpoint_name,
        ContentType="software/json",
        Physique=json.dumps({
            "kind": "add_points",
            "session_id": session_id,
            "factors": [p["coordinates"] for p in factors],
            "labels": [p["label"] for p in factors],
            "clear_old_points": clear_old_point,
        }),
        SessionId=session_id,
        Settle for="software/jsonlines"
    )

# Parse response stream
parser = StreamParser()
for occasion in response['Body']:
    parser.write(occasion)

# Intermediate Response
masks = parser.get_responses()
    
response = runtime_client.invoke_endpoint_with_response_stream(
        EndpointName=endpoint_name,
        ContentType="software/json",
        Physique=json.dumps({
            "kind": "predict",
            "session_id": session_id,
            "multimask_output": True,
            "return_logits": True
        }),
        SessionId=session_id,
        Settle for="software/jsonlines"
    )

# Parse response stream
parser = StreamParser()
for occasion in response['Body']:
    parser.write(occasion)

masks = parser.get_responses()

# Finish session
end_session(session_id)

We obtain the next output (parsed and visualized).

Video predictor

We now reveal the right way to immediate Meta SAM 2.1 for object monitoring on video. One use case could be for ergonomic knowledge assortment and coaching functions. You should use the video predictor to investigate the motion and posture of people in actual time, serving as a strategy to scale back harm and enhance efficiency by setting alarms for unhealthy posture or actions. Let’s begin by accessing the basketball-layup.mp4 file [1] from the jumpstart-cache-prod S3 bucket outlined within the following code:

basketball_mp4 = "basketball-layup.mp4"

#Obtain video
download_from_s3(key_filenames=[basketball_mp4])
show(Video(filename=basketball_mp4))

Video:

The next code reveals how one can arrange the immediate format to trace objects within the video. The primary object will use coordinates to trace and never monitor, and the second object will monitor one coordinate.

# Begin session
session_id = start_session("video", basketball_mp4)

# Object 1
prompts1 = [
        {"type": "point", "coordinates": [1478, 649], "label": 1},
        {"kind": "level", "coordinates": [1433, 689], "label": 0},
    ]
    
# Extract factors and labels
factors = []
labels = []
for immediate in prompts1:
    if immediate["type"] == "level":
        factors.append(immediate["coordinates"])
        labels.append(immediate["label"])

request = {
        "kind": "add_points",
        "session_id": session_id,
        "frame_index": 0,
        "object_id": 1,
        "factors": factors,
        "labels": labels,
        "clear_old_points": True,
    }
    
# Add a number of factors
response = runtime_client.invoke_endpoint_with_response_stream(
        EndpointName=endpoint_name,
        ContentType="software/json",
        Physique=json.dumps(request),
        SessionId=session_id,
        Settle for="software/jsonlines"
    )

# Parse response stream
parser = StreamParser()
for occasion in response['Body']:
    parser.write(occasion)

# Intermediate Response
masks = parser.get_responses()

# Object 2
prompts2 = [{"type": "point", "coordinates": [1433, 689], "label": 1}]

# Extract factors and labels
factors = []
labels = []
for immediate in prompts2:
    if immediate["type"] == "level":
        factors.append(immediate["coordinates"])
        labels.append(immediate["label"])

request = {
        "kind": "add_points",
        "session_id": session_id,
        "frame_index": 0,
        "object_id": 2,
        "factors": factors,
        "labels": labels,
        "clear_old_points": True,
    }
    
# Add a number of factors
response = runtime_client.invoke_endpoint_with_response_stream(
        EndpointName=endpoint_name,
        ContentType="software/json",
        Physique=json.dumps(request),
        SessionId=session_id,
        Settle for="software/jsonlines"
    )

# Parse response stream
parser = StreamParser()
for occasion in response['Body']:
    parser.write(occasion)

# Intermediate Response
masks = parser.get_responses()
    
response = runtime_client.invoke_endpoint_with_response_stream(
        EndpointName=endpoint_name,
        ContentType="software/json",
        Physique=json.dumps({
            "kind": "propagate_in_video",
            "session_id": session_id,
            "start_frame_index": 0,
        }),
        SessionId=session_id,
        Settle for="software/jsonlines"
    )

# Parse response stream
parser = StreamParser()
for occasion in response['Body']:
    parser.write(occasion)

masks = parser.get_responses()

# Finish session
end_session(session_id)

We obtain the next output (parsed and visualized).
