<p><code>mxnet</code> package is not installing in r (on windows 10) when I follow the steps given in its documentation.</p>

<pre><code>install.packages("drat", repos="https://cran.rstudio.com")

install.packages("mxnet")
</code></pre>

<p>It gives the following result</p>

<p>Kindly help me resolve this issue. I'm using R version 3.3.0. Is there any other way of installing it in R?</p>
