title: Using php-ai/php-ml with php
body: <p>I am using notepad++. I have installed composer and from command line I have tried to install the php-ai/php-ml using the following line of code <code>composer require php-ai/php-ml</code>. My cmd tells me that this is successfully installed and everything seems okay. </p>
  
  <p>However, in my index.php file if I try to use any of the libraries in the package php-ai/php-ml for example: <code>use Phpml\Dataset\CsvDataset;</code> I get the following error:</p>
  
  <blockquote>
    <p>Fatal error: Uncaught Error: Class 'Phpml\Dataset\CsvDataset' not found in C:\xampp\htdocs\test\index.php:5 Stack trace: #0 {main} thrown in C:\xampp\htdocs\test\index.php on line 5</p>
  </blockquote>
  
  <p>Line 5 is the line which i request to use the library. Do i have to import these libraries or anything? </p>
