<span id="recommend-saving-models"></span><h3>Recommended approach for saving a model<a class="headerlink" href="#recommended-approach-for-saving-a-model" title="Permalink to this headline">¶</a></h3>
<p>There are two main approaches for serializing and restoring a model.</p>
<p>The first (recommended) saves and loads only the model parameters:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">torch</span><span class="o">.</span><span class="n">save</span><span class="p">(</span><span class="n">the_model</span><span class="o">.</span><span class="n">state_dict</span><span class="p">(),</span> <span class="n">PATH</span><span class="p">)</span>
</pre></div>
</div>
<p>Then later:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">the_model</span> <span class="o">=</span> <span class="n">TheModelClass</span><span class="p">(</span><span class="o">*</span><span class="n">args</span><span class="p">,</span> <span class="o">**</span><span class="n">kwargs</span><span class="p">)</span>
<span class="n">the_model</span><span class="o">.</span><span class="n">load_state_dict</span><span class="p">(</span><span class="n">torch</span><span class="o">.</span><span class="n">load</span><span class="p">(</span><span class="n">PATH</span><span class="p">))</span>
</pre></div>
</div>
<p>The second saves and loads the entire model:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">torch</span><span class="o">.</span><span class="n">save</span><span class="p">(</span><span class="n">the_model</span><span class="p">,</span> <span class="n">PATH</span><span class="p">)</span>
</pre></div>
</div>
<p>Then later:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">the_model</span> <span class="o">=</span> <span class="n">torch</span><span class="o">.</span><span class="n">load</span><span class="p">(</span><span class="n">PATH</span><span class="p">)</span>
</pre></div>
</div>
<p>However in this case, the serialized data is bound to the specific classes
and the exact directory structure used, so it can break in various ways when
used in other projects, or after some serious refactors.</p>
