<p>I looked into <code>mlpack-2.0.2/src/mlpack/core/tree/cosine_tree/cosine_tree.cpp</code>, and found it use Monte Carlo, so I tested Armadillo with the following codes:</p>
<pre><code>#include <iostream>
#include <armadillo>
using namespace std;
using namespace arma;
int main(int argc, char const* argv[])
{
cout << "check 1" << endl;
cout << arma_rng::randn<double>() << endl;
cout << "check 2" << endl;
return 0;
}
</code></pre>
<p>And the output is</p>
<pre><code>check 1
</code></pre>
<p>It stuck here too! I tried Armadillo 6.700.7 and 7.200.2, both have this problem. I don't know if this is related.</p>
