Stages</h2><p>By default <code>pio train</code> runs through the whole training 
process including <a href="/templates/recommendation/dase/">DataSource, 
Preparator and Algorithm</a>. To speed up the development and debug cycle, you 
can stop the process after each stage to verify it has completed 
correctly.</p><p>If you have modified DataSource and want to confirm the 
TrainingData is generated as expected, you can run <code>pio train</code> with 
<code>--stop-after-read</code> option:</p><div class="highlight shell"><table

process after the TrainingData is generated.</p><p>For example, if you are 
running <a href="/templates/recommendation/quickstart/">Recommendation 
Template</a>, you should see the the training process stops after the 
TrainingData is printed.</p><div class="highlight shell"><table
