<section id="install-nerfstudio-dependencies">
<h3>1. Install Nerfstudio dependencies<a class="headerlink" href="#install-nerfstudio-dependencies" title="Permalink to this heading">#</a></h3>
<p>Please follow the Nerfstudio <a class="reference external" href="https://docs.nerf.studio/quickstart/installation.html">installation guide</a> to create an environment and install dependencies.</p>
</section>
<section id="install-the-repository">
<h3>2. Install the repository<a class="headerlink" href="#install-the-repository" title="Permalink to this heading">#</a></h3>
<p>Run the following commands:
<code class="docutils literal notranslate"><span class="pre">pip</span> <span class="pre">install</span> <span class="pre">git+https://github.com/KevinXu02/splatfacto-w</span></code></p>
<p>Then, run <code class="docutils literal notranslate"><span class="pre">ns-install-cli</span></code>.</p>
</section>
<section id="check-installation">
<h3>3. Check installation<a class="headerlink" href="#check-installation" title="Permalink to this heading">#</a></h3>
<p>Run <code class="docutils literal notranslate"><span class="pre">ns-train</span> <span class="pre">splatfacto-w</span> <span class="pre">--help</span></code>. You should see the help message for the splatfacto-w method.</p>

<h2>Running Splafacto-w<a class="headerlink" href="#running-splafacto-w" title="Permalink to this heading">#</a></h2>
<p>To train with it, download the train/test tsv file from the bottom of <a class="reference external" href="https://nerf-w.github.io/">nerf-w</a> and put it under the data folder (or copy them from <code class="docutils literal notranslate"><span class="pre">./splatfacto-w/dataset_split</span></code>). For instance, for Brandenburg Gate the path would be <code class="docutils literal notranslate"><span class="pre">your-data-folder/brandenburg_gate/brandenburg.tsv</span></code>. You should have the following structure in your data folder:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="o">|---</span><span class="n">brandenburg_gate</span>
<span class="o">|</span> <span class="o">|---</span><span class="n">dense</span>
<span class="o">|</span> <span class="o">|</span> <span class="o">|---</span><span class="n">images</span>
<span class="o">|</span> <span class="o">|</span> <span class="o">|---</span><span class="n">sparse</span>
<span class="o">|</span> <span class="o">|</span> <span class="o">|---</span><span class="n">stereo</span>
<span class="o">|</span> <span class="o">|---</span><span class="n">brandenburg</span><span class="o">.</span><span class="n">tsv</span>
</pre></div>
</div>
<p>Then, run the command:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">ns</span><span class="o">-</span><span class="n">train</span> <span class="n">splatfacto</span><span class="o">-</span><span class="n">w</span> <span class="o">--</span><span class="n">data</span> <span class="p">[</span><span class="n">PATH</span><span class="p">]</span>
</pre></div>
</div>
<p>If you want to train datasets without nerf-w’s train/test split or your own datasets, we provided a light-weight version of the method for general cases. To train with it, you can run the following command</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">ns</span><span class="o">-</span><span class="n">train</span> <span class="n">splatfacto</span><span class="o">-</span><span class="n">w</span><span class="o">-</span><span class="n">light</span> <span class="o">--</span><span class="n">data</span> <span class="p">[</span><span class="n">PATH</span><span class="p">]</span> <span class="p">[</span><span class="n">dataparser</span><span class="p">]</span>
</pre></div>
</div>
<p>For phototourism, the <code class="docutils literal notranslate"><span class="pre">dataparser</span></code> should be <code class="docutils literal notranslate"><span class="pre">colmap</span></code> and you need to change the colmap path through the CLI because phototourism dataparser does not load 3D points.</p>
