// Example code for using SageMaker model serving and inference protocols
import boto3

sagemaker = boto3.client('sagemaker')

# Create a SageMaker model
model = sagemaker.create_model(
    ModelName='MyModel',
    ExecutionRoleArn='arn:aws:iam::123456789012:role/service-role/AmazonSageMaker-ExecutionRole-20200101T000001',

        'ModelDataUrl': 's3://my-bucket/model.tar.gz'
    }
)

# Create a SageMaker endpoint
endpoint = sagemaker.create_endpoint(
    EndpointName='MyEndpoint',
    EndpointConfigName='MyEndpointConfig'
)

# Send an inference request to the model
response = sagemaker.invoke_endpoint(
    EndpointName='MyEndpoint',
    Body=b'{"input_data": [1, 2, 3]}',

How to Fix Accelerometer in Mobile Phone

The accelerometer is a crucial sensor in a mobile phone that measures the device's orientation, movement, and acceleration. If the accelerometer is not working properly, it can cause issues with the phone's screen rotation, gaming, and other features that rely on motion sensing. In this article, we will explore the steps to fix a faulty accelerometer in a mobile phone. Causes of Accelerometer Failure Before we dive into the steps to fix the accelerometer, let's first understand the common causes of accelerometer failure: Physical damage: Dropping the phone or exposing it to physical stress can damage the accelerometer. Water damage: Water exposure can damage the accelerometer and other internal components. Software issues: Software glitches or bugs can cause the accelerometer to malfunction. Hardware failure: The accelerometer can fail due to a manufacturing defect or wear and tear over time. Symptoms of a Faulty Accelerometer If the accelerometer i...

Customizing the Appearance of a Bar Chart in Matplotlib

Matplotlib is a powerful data visualization library in Python that provides a wide range of tools for creating high-quality 2D and 3D plots. One of the most commonly used types of plots in matplotlib is the bar chart. In this article, we will explore how to customize the appearance of a bar chart in matplotlib. Basic Bar Chart Before we dive into customizing the appearance of a bar chart, let's first create a basic bar chart using matplotlib. Here's an example code snippet: import matplotlib.pyplot as plt # Data for the bar chart labels = ['A', 'B', 'C', 'D', 'E'] values = [10, 15, 7, 12, 20] # Create the bar chart plt.bar(labels, values) # Show the plot plt.show() This code will create a simple bar chart with the labels on the x-axis and the values on the y-axis. Customizing the Appearance of the Bar Chart Now that we have a basic bar chart, let's customize its appearance. Here are some ways to do it: Changing the...
