Python Top Libraries You Need to Create ML Model

By
Creating a Model of Machine Learning in Python, you need two libraries. One is 'NUMPY' and the other one is 'PANDA'.


For this project, we are using Python Libraries to Create a Model.
What Are Key Libraries You Need I have explained in the below steps. You need Two.
NUMPY - It has the capabilities of CalculationsPANDA - It has the capabilities of Data processing. To Build a model of Machine learning you need the right kind of data. So, to use data for your project, the Data should be refined. Else, it will not give accurate results. Data AnalysisData Pre-processing How to Import Libraries in Pythonimportnumpy as np # linear algebra
importpandas as pd # data processing, CSV file I/O (e.g. pd.read_csv)

How to Check NUMPY/Pandas installed After '.' you need to give double underscore on both the sides of version. 
How Many Types of Data You Need You need two types of data. One is data to build a model and the other one is data you need to test the model. Data to build…

Aws Service catalog helps organizations to manage their IT services.

List of Top AWS  Services

  1. EC2
  2. Lambda
  3. S3
  4. DynamoDB
  5. IAM
  6. Amazon Cognito
  7. Device Farm
  8. Mobile analytics
  9. SNS

AWS EC2 Instance

EC2: Amazon Elastic Compute Cloud (EC2) provides secure, scalable, on-demand hardware virtualization in the cloud.
Using Amazon EC2 eliminates the need to invest in server hardware up front so that users can focus on, develop, and deploy applications faster. 

EC2 instances come in various hardware configurations and include an operating system.

Lambda Function in AWS

AWS Lambda lets users run snippets of code without provisioning an infrastructure. 

This service is billed on a pay-as-you-go model, with users only paying for the execution time of their lambda code. 

There is no charge when code is not running. Lambda code can be set up to automatically trigger from other AWS services or called directly from any web or mobile app.

Aws S3 Console

Amazon Simple Storage Service is a secure, durable, and scalable cloud-based object store. Using this service, you can store your files in the cloud.

DynamoDB

Amazon DynamoDB is a high-performance, scalable cloud-based NoSQL database service.

Aws IAM Role

Amazon Identity and Access Management (IAM) lets you securely control who can access your AWS resources, what resources they can access, and what they can do with these resources.

Amzon Cognito Review

Amazon Cognito allows you to create identity profiles for your app's users and allows them to sign in to the app with their Amazon, Facebook, Twitter, or Google accounts.

After users have authenticated from the app, the app is given a token that can be used to access AWS cloud resources securely. 

Amazon Cognito also offers a service that allows authenticated users to sync their app data on different devices.

Aws Device Farm

Amazon Device Farm is an app testing service that allows you to upload your app and run a set of automated tests and a set of real-time tests on physical devices hosted by Amazon.

Both Android and iOS apps are supported.

Aws Mobile Analytics

Amazon Mobile Analytics allows you to collect and visualize app usage data. A set of reports is generated based on the collected data. 

You can export the analytics data to other AWS cloud services for further processing.

Aws SNS topic

Amazon Simple Notification Service (SNS) enables you to send push messages.

These messages can be pushed to mobile application, e-mail inboxes, web servers, and other AWS cloud services.

SNS supports various protocols including SMS, e-mail, and HTTP/S.

Summary

Total 8 AWS services absolutely need for every developer working on AWS.
