title: Laravel DivineOmega / eloquent-attribute-value-prediction not working as expected
body: <p>I´m trying to extract a series of tags from a given text that describes a job opening. So I set up the package as described on Github having the following model:</p>
  <pre><code>namespace App\Models;
  
  use DivineOmega\EloquentAttributeValuePrediction\Interfaces\HasPredictableAttributes;
  use DivineOmega\EloquentAttributeValuePrediction\Traits\PredictsAttributes;
  use Illuminate\Database\Eloquent\Model;
  
  class MLTags extends Model implements HasPredictableAttributes
  {
      use PredictsAttributes;
      protected $table = 'ml_tags';
  
      protected $casts = [
          'tag' =&gt; 'string',
          'description' =&gt; 'string',
      ];
  
      public function registerPredictableAttributes(): array
      {
          return [
              'tag' =&gt; [
                  'description',
              ],
          ];
      }
  }
  </code></pre>
  <p>The MySQL table contents (data I assume is used for training), for <strong>ml_tags</strong> table are:</p>
  <pre><code>id|             description                    | tag
  1 | &quot;...looking for an engineer...&quot;            | engineering
  2 | &quot;... architect with 5 years experience...&quot; | architecture
  3 | &quot;... design and construction documents...&quot; | architecture
  4 | ...job opening descriptive text4...        | finances
  5 | ...job opening descriptive text5...        | urbanism
  6 | ...job opening descriptive text6...        | engineering
  7 | ...job opening descriptive text7...        | technical
  8 | ...job opening descriptive text8...        | architecture
  ...100 | ...job opening descriptive text100... | civil
  </code></pre>
  <p>Then on the console I run:</p>
  <pre><code>php artisan eavp:train \App\Models\MLTags
  </code></pre>
  <p>And on Tinker:</p>
  <pre><code>$tag = new MLTags
  
  $tag-&gt;description = 'new job opening descriptive text'
  
  $tag-&gt;getPredictions('tag')
  </code></pre>
  <p>But regardless of what I type for 'new job opening descriptive text', I always get the same exact results:</p>
  <pre><code>[
       &quot;engineering&quot; =&gt; 0.39366507192329,
       &quot;electrical&quot; =&gt; 0.39366507192329,
       &quot;mechanical&quot; =&gt; 0.21266985615342,
       &quot;architecture&quot; =&gt; 0.0,
       &quot;civil&quot; =&gt; 0.0,
       &quot;technical&quot; =&gt; 0.0,
       &quot;administration&quot; =&gt; 0.0,
       &quot;finances&quot; =&gt; 0.0,
       &quot;urbanism&quot; =&gt; 0.0
     ]
  </code></pre>
  <p>What am I missing?</p>
