<h1>Configuring Logging for NMSLIB<a class="headerlink" href="#configuring-logging-for-nmslib" title="Permalink to this headline"></a></h1>
<p>This library logs to a Python logger named <code class="docutils literal notranslate"><span class="pre">nmslib</span></code>. This lets
you fully control the log messages produced by nmslib in Python.</p>
<p>For instance, to log everything produced by nmslib to a default
python logger:</p>
<div class="highlight-python notranslate"><div class="highlight"><pre><span></span><span class="c1"># setup basic python logging</span>
<span class="kn">import</span> <span class="nn">logging</span>
<span class="n">logging</span><span class="o">.</span><span class="n">basicConfig</span><span class="p">(</span><span class="n">level</span><span class="o">=</span><span class="n">logging</span><span class="o">.</span><span class="n">DEBUG</span><span class="p">)</span>
<span class="c1"># importing nmslib logs some debug messages on startup, that</span>
<span class="c1"># that will be output to the python log handler created above</span>
<span class="kn">import</span> <span class="nn">nmslib</span>
</pre></div>
</div>
<p>To quiet these messages you can just set the level for nmslib
as appropiate:</p>
<div class="highlight-python notranslate"><div class="highlight"><pre><span></span><span class="c1"># setup basic python logging</span>
<span class="kn">import</span> <span class="nn">logging</span>
<span class="n">logging</span><span class="o">.</span><span class="n">basicConfig</span><span class="p">(</span><span class="n">level</span><span class="o">=</span><span class="n">logging</span><span class="o">.</span><span class="n">DEBUG</span><span class="p">)</span>
<span class="c1"># Only log WARNING messages and above from nmslib</span>
<span class="n">logging</span><span class="o">.</span><span class="n">getLogger</span><span class="p">(</span><span class="s1">&#39;nmslib&#39;</span><span class="p">)</span><span class="o">.</span><span class="n">setLevel</span><span class="p">(</span><span class="n">logging</span><span class="o">.</span><span class="n">WARNING</span><span class="p">)</span>
