<h2>Highlights</h2>
<p>PyTorch Lightning 1.6 is the work of 99 contributors who have worked on features, bug-fixes, and documentation for a total of over 750 commits since 1.5. This is our most active release yet. Here are some highlights:</p>
<h3>Introducing Intel's Habana Accelerator</h3>
<p>Lightning 1.6 now supports the Habana® framework, which includes Gaudi® AI training processors. Their heterogeneous architecture includes a cluster of fully programmable Tensor Processing Cores (TPC) along with its associated development tools and libraries and a configurable Matrix Math engine.</p>
<p>You can leverage the <a href="https://pytorch-lightning.readthedocs.io/en/stable/accelerators/hpu.html">Habana</a> hardware to accelerate your Deep Learning training workloads simply by passing:</p>
<pre lang="python"><code>trainer = pl.Trainer(accelerator=&quot;hpu&quot;)
<h1>single Gaudi training</h1>
<p>trainer = pl.Trainer(accelerator=&quot;hpu&quot;, devices=1)</p>
<h1>distributed training with 8 Gaudi</h1>
<p>trainer = pl.Trainer(accelerator=&quot;hpu&quot;, devices=8)
</code></pre></p>
<h3>The Bagua Strategy</h3>
<p>The <a href="https://pytorch-lightning.readthedocs.io/en/stable/accelerators/gpu.html#bagua">Bagua Strategy</a> is a deep learning acceleration framework that supports multiple, advanced distributed training algorithms with state-of-the-art system relaxation techniques. Enabling <a href="https://github.com/BaguaSys/bagua">Bagua</a>, which can be considerably faster than vanilla PyTorch DDP, is as simple as:</p>
<pre lang="python"><code>trainer = pl.Trainer(strategy=&quot;bagua&quot;)
<h1>or to choose a custom algorithm</h1>
<p>trainer = pl.Trainer(strategy=BaguaStrategy(algorithm=&quot;gradient_allreduce&quot;)  # default
</code></pre></p>
<h3>Towards stable Accelerator, Strategy, and Plugin APIs</h3>
<p>The <code>Accelerator</code>, <code>Strategy</code>, and <code>Plugin</code> APIs are a core part of PyTorch Lightning. They're where all the distributed boilerplate lives, and we're constantly working to improve both them and the overall PyTorch Lightning platform experience.</p>
<p>In this release, we've made some large changes to achieve that goal. Not to worry, though! The only users affected by these changes are those who use custom implementations of Accelerator and Strategy (<code>TrainingTypePlugin</code>) as well as certain Plugins. In particular, we want to highlight the following changes:</p>
<ul>
<li>All <code>TrainingTypePlugin</code>s have been renamed to <code>Strategy</code> (<a href="https://github-redirect.dependabot.com/PyTorchLightning/pytorch-lightning/pull/11120">#11120</a>). Strategy is a more appropriate name because it encompasses more than simply training communcation. This change is now aligned with the changes we implemented in 1.5, which introduced the new <a href="https://github.com/PyTorchLightning/pytorch-lightning/releases/tag/1.5.0#strategy-and-devices"><code>strategy</code> and <code>devices</code> flags to the Trainer</a>.</li>
</ul>
