Python Packages in SQL Server – Get Started with SQL Server Machine Learning Services

Introduction

When installing Machine Learning Services in SQL Server by default few Python Packages are installed. In this article, we will have a look on how to get those installed python package information.

Python Packages

When we choose Python as Machine Learning Service during installation, the following packages are installed in SQL Server,

  • revoscalepy – This Microsoft Python package is used for remote compute contexts, streaming, parallel execution of rx functions for data import and transformation, modeling, visualization, and analysis.
  • microsoftml – This is another Microsoft Python package which adds machine learning algorithms in Python.
  • Anaconda 4.2 – Anaconda is an opensource Python package

Pagination Example In Laravel

In this post I will show you pagination example in laravel, as we all know pagination is very common feature in all websites, if we want to display specific number of details or images then we can use pagination.

aravel provide paginate method and it will automatically takes care of setting the proper limit and offset based on the current page being viewed by the user.here i will show you how to use pagination in laravel, So I have try paginate method in laravel.

How to Generate Server-Side PDF Reports With Puppeteer, D3 & Handlebars

Looking for a way to create a design-heavy, data-driven, beautifully styled PDF report—server-side with similar tools to what you are already using on the front-end? Stop your Google search. You’ve come to the right place. I was in the same boat as you a few months ago while helping a client with this exact problem. In order to accomplish this feat, I developed a four-step solution using Puppeteer, D3, and handlebars. In this post, I’ll give you step by step instructions on creating server-side pdf reports. Let’s dive in.

An example of a PDF page generated using this method.

An example of a PDF page generated using this method.

In this post, we’ll cover:

  • Setting up Puppeteer and Handlebars
  • Creating a generator to make our PDF
  • Building out a handlebars template
  • Adding the finishing touches

The CHallenges of Creating These PDF Reports:

Because we’re using a template framework to access standard web technologies along with Puppeteer to manage the PDF, we’ll need to think about these things during development:

  • Pages will manually need to be constrained.
  • We won’t have access to CSS media props other than “screen.” (no “page-break-after” or the print media type)
  • We won’t be able to use dev tools to debug irregularities once the PDF is compiled and rendered.
  • Puppeteer itself adds extra build time and size to your deployments.
  • Generating a report can take a while depending on file size.

For this example, let’s assume we already have the base of our project up and running Node/Express, and some type of ORM and DB solutions. We’re all set to feed our sweet, sweet data into a report.

The Tools We Need to Make This Happen

Handlebars

HTML templating framework from the Mustache family. This allows for Partial templating (fancy talk for components) and custom and built-in helper functionality to expand on our logic.

npm install handlebars

Example using partials and built-in blocks

{{#each poleComparison as |page|}}
<div class="page">
  {{#each page.pairs as |polePair|}}
    {{> comparison-header polePair=polePair }}
        <div class="comparison-tables">
            {{> comparison-body polePair=polePair }}
        </div>
  {{/each}}
  {{> footer @root }}
</div>
{{/each}}

Puppeteer

A node library that will provide us access to a chrome headless instance for generating the PDF based on our compiled Handlebars templates.

npm install puppeteer

A list of use cases:

  • Generate screenshots and PDFs of pages.
  • Crawl a SPA (Single-Page Application) and generate pre-rendered content (i.e. “SSR” (Server-Side Rendering)).
  • Create an up-to-date, automated testing environment.
  • Test Chrome Extensions.

D3 (Data-Driven Documents)

D3.js is a JavaScript library for manipulating documents based on data. D3 helps you bring data to life using HTML, SVG, and CSS. D3’s emphasis on web standards gives you the full capabilities of modern browsers without tying yourself to a proprietary framework, combining powerful visualization components and a data-driven approach to DOM manipulation.

Get Started with SQL Server Machine Learning Services

We know Humans learn from their past experiences. Mean while Machines follow Instructions given by Humans. But what if Human can train Machines to learn from the past data?. In simple, this is what Machine learning is !!!. SQL Server has capabilities of Machine Learning. In this article, we will discuss about the capabilities of Machine Learning in SQL Server.
