<p>I cannot declare type:</p>

<div class="highlight highlight-source-c++"><pre><span class="pl-k">using</span> KnnModel = mlpack::neighbor::NeighborSearch&lt;mlpack::neighbor::NearestNeighborSort,
                                                  mlpack::metric::ManhattanDistance,
                                                  arma::fmat,
                                                  mlpack::tree::KDTree&gt;;</pre></div>

<p>error:</p>

<pre><code>/usr/include/mlpack/core/tree/hrectbound_implhpp:372:30: 
error: no matching function for call to 
‘arma::Col&lt;double&gt;::Col(const arma::Op&lt;arma::subview&lt;float&gt;, arma::op_min&gt;)’
   arma::vec mins(min(data, 1));
</code></pre>

<p>Is threre no implementation for float or I'm doing something wrong?</p>
