<p>This guide will walk you through training a model using Refiners. We built the <code>training_utils</code> module to provide a simple, flexible, statically type-safe interface.</p>
|
||
|
|
<p>We will use a simple model and a toy dataset for demonstration purposes. The model will be a simple <a href="https://en.wikipedia.org/wiki/Autoencoder">autoencoder</a>, and the dataset will be a synthetic dataset of rectangles
|
||
|
|
of different sizes.</p>
|
||
|
|
<h2 id="pre-requisites">Pre-requisites<a class="headerlink" href="#pre-requisites" title="Permanent link">¶</a></h2>
|
||
|
|
<p>We recommend installing Refiners targeting a specific commit hash to avoid unexpected changes in the API. You also
|
||
|
|
get the benefit of having a perfectly reproducible environment.</p>

<p>We now have a fully functional autoencoder that takes an image with one channel of
|

|
|
size 64x64 and compresses it to a vector of size 256 (x16 compression). The decoder then takes this vector and reconstructs the original image.</p>

<p>We will now create a Trainer class to handle the training loop. This class will manage the model, the optimizer, the loss function, and the dataset. It will also orchestrate the training loop and the evaluation loop.</p>
|
||
|
|
<p>But first, we need to define the batch type that will be used to represent a batch for the forward and backward pass and the configuration associated with the trainer.</p>

<h3 id="batch">Batch<a class="headerlink" href="#batch" title="Permanent link">¶</a></h3>

<p>Our batches are composed of a single tensor representing the images. We will define a simple <code>Batch</code> type to implement this.</p>

<p>We will now define the configuration for the autoencoder. It holds the configuration for the training loop, the optimizer, and the learning rate scheduler. It should inherit <code>refiners.training_utils.BaseConfig</code> and has the following mandatory attributes:</p>
|
||
|
|
<ul>
|
||
|
|
<li><code>TrainingConfig</code>: The configuration for the training loop, including the duration of the training, the batch size, device, dtype, etc.</li>
|
||
|
|
<li><code>OptimizerConfig</code>: The configuration for the optimizer, including the learning rate, weight decay, etc.</li>

<li><code>LRSchedulerConfig</code>: The configuration for the learning rate scheduler, including the scheduler type, parameters, etc.</li>

<p>We can now define the Trainer subclass. It should inherit from <code>refiners.training_utils.Trainer</code> and implement the following methods:</p>
|
||
|
|
<ul>
|
||
|
|
<li><code>create_data_iterable</code>: The <code>Trainer</code> will call this method to create and cache the data iterable. During training, the loop will pull batches from this iterable and pass them to the <code>compute_loss</code> method. Every time the iterable is exhausted, an epoch ends.</li>
|
||
|
|
<li><code>compute_loss</code>: This method should take a Batch and return the loss tensor.</li>
|
||
|
|
</ul>
|
||
|
|
<p>Here is a simple implementation of the <code>create_data_iterable</code> method. For this toy example, we will generate a simple list of <code>Batch</code> objects containing random masks. Later you can replace this with <code>torch.utils.data.DataLoader</code> or any other data loader with more complex features that support shuffling, parallel loading, etc.</p>

<p>For the Trainer to be able to handle the model, we need to register it. </p>
|
||
|
|
<p>We need two things to do so: </p>
|
||
|
|
<ul>
|
||
|
|
<li>Add <code>refiners.training_utils.ModelConfig</code> attribute to the Config named <code>autoencoder</code>.</li>
|
||
|
|
<li>Add a method to the Trainer subclass that returns the model decorated with <code>@register_model</code> decorator. This method should take the <code>ModelConfig</code> as an argument. The Trainer's <code>__init__</code> will register the models and add any parameters to the optimizer that have <code>requires_grad</code> enabled.</li>
|
||
|
|
</ul>
|
||
|
|
<p>After registering the model, the <code>self.autoencoder</code> attribute will be available in the Trainer.</p>

<p>Exactly like models, we need to register the callback to the Trainer. We can do so by adding a <code>CallbackConfig</code> attribute to the config named <code>logging</code> and adding a method to the Trainer class that returns the callback decorated with <code>@register_callback</code> decorator. </p>
