|

<p>Dataset pre-processing is the step where Axolotl takes each dataset you’ve configured alongside
|
||
the <a href="dataset-formats">dataset format</a> and prompt strategies to:</p>
|
||
<ul>
|
||
<li>parse the dataset based on the <em>dataset format</em></li>
|
||
<li>transform the dataset to how you would interact with the model based on the <em>prompt strategy</em></li>
|
||
<li>tokenize the dataset based on the configured model & tokenizer</li>
|
||
<li>shuffle and merge multiple datasets together if using more than one</li>
|
||
</ul>
|
||
<p>The processing of the datasets can happen one of two ways:</p>
|
||
<ol type="1">
|
||
<li>Before kicking off training by calling <code>axolotl preprocess config.yaml --debug</code></li>
|
||
<li>When training is started</li>
|
||
</ol>

|
||
<h3 class="anchored" data-anchor-id="what-are-the-benefits-of-pre-processing">What are the benefits of pre-processing?</h3>
|
||
<p>When training interactively or for sweeps
|
||
(e.g. you are restarting the trainer often), processing the datasets can oftentimes be frustratingly
|
||
slow. Pre-processing will cache the tokenized/formatted datasets according to a hash of dependent
|
||
training parameters so that it will intelligently pull from its cache when possible.</p>
|
||
<p>The path of the cache is controlled by <code>dataset_prepared_path:</code> and is often left blank in example
|
||
YAMLs as this leads to a more robust solution that prevents unexpectedly reusing cached data.</p>
|
||
<p>If <code>dataset_prepared_path:</code> is left empty, when training, the processed dataset will be cached in a
|
||
default path of <code>./last_run_prepared/</code>, but will ignore anything already cached there. By explicitly
|
||
setting <code>dataset_prepared_path: ./last_run_prepared</code>, the trainer will use whatever pre-processed
|
||
data is in the cache.</p>

<section id="what-are-the-edge-cases" class="level3">
|
||
<h3 class="anchored" data-anchor-id="what-are-the-edge-cases">What are the edge cases?</h3>
|
||
<p>Let’s say you are writing a custom prompt strategy or using a user-defined
|
||
prompt template. Because the trainer cannot readily detect these changes, we cannot change the
|
||
calculated hash value for the pre-processed dataset.</p>
|
||
<p>If you have <code>dataset_prepared_path: ...</code> set
|
||
and change your prompt templating logic, it may not pick up the changes you made and you will be
|
||
training over the old prompt.</p>
