<h2>Saving a trained model to disk<a class="headerlink" href="#saving-a-trained-model-to-disk" title="Permalink to this headline"></a></h2>

<p>Saving a model to disk involves saving two files to a target directory. These files store the model weights and the maui parameters (the arguments the maui model was instantiated with). <a class="reference internal" href="maui.html"><span class="doc">The Maui Class</span></a> implements a the save function</p>

<dl class="function">

<dt id="maui.Maui.save">

<code class="descclassname">maui.Maui.</code><code class="descname">save</code><span class="sig-paren">(</span><em>self</em>, <em>destdir</em><span class="sig-paren">)</span><a class="headerlink" href="#maui.Maui.save" title="Permalink to this definition"></a></dt>

<dd><p>Save a maui model to disk, so that it may be reloaded later using <code class="docutils literal notranslate"><span class="pre">load()</span></code></p>

<p>destdir:    destination directory in which to save model files</p>

</dd></dl>



<p>The function takes one required parameter, the destination directory where the two files will be saved. It is called directly on a maui model, like</p>

<div class="highlight-python notranslate"><div class="highlight"><pre><span></span><span class="n">maui_model</span><span class="o">.</span><span class="n">save</span><span class="p">(</span><span class="s1">&#39;/path/to/dir&#39;</span><span class="p">)</span>

<div class="section" id="loading-a-model-from-disk">

<h2>Loading a model from disk<a class="headerlink" href="#loading-a-model-from-disk" title="Permalink to this headline"></a></h2>

<p>Loading a model involves instantiating a new Maui instance using the parameters that were used on the model that is saved to disk, and then populating the weights of the model to the previously trained weights. Once a model is loaded, it can be used to transform new data to the latent space, or it can be trained further. <a class="reference internal" href="maui.html"><span class="doc">The Maui Class</span></a> has a static function to load a model from disk</p>

<dl class="function">

<dt id="maui.Maui.load">

<dd><p>Load a maui model from disk, which was previously saved using <code class="docutils literal notranslate"><span class="pre">save()</span></code></p>

<p>dir:    The directory from which to load the maui model</p>

<p>maui_model: a maui model that was previously saved to disk</p>

</dd></dl>



<p>It is called directly on the Maui class, like</p>
