Fatal Error: Class not Found when using namespaces

I have been trying to use namespaces for the first time in ages and I am running into the below problem. I am currently using Composer for a PSR-4 autoloader and I keep getting the error: Fatal error: Class 'API\Library\Config' not found in C:\wamp64\www\project\src\index.php on line 14

composer.json

"autoload": {
    "psr-4": {
        "API\\": "src",
        "API\\Library\\": "src/Library",
        "API\\Controllers\\": "src/Application/Controllers"
    }
}

src/index.php

namespace API;
include_once('vendor/autoload.php');
use API\Library\Config;
$config = new Config(); //line 18

The Folder layout is as such:

Its because src is the parent folder. Ideally vendor would be in the same directory as src.

"autoload": {
    "psr-4": {
        "API\\": "",
        "API\\Library\\": "Library",
        "API\\Controllers\\": "Application/Controllers"
    }
}

Would work, or you should restructure your directories.

Also you can leave out "API\\Library\\": "Library", as it will be picked up by "API\\": "",
