MXNET build model error on r
<p>When I try to use mxnet to build a feedforward model it appeared the following error:</p>

<blockquote>
  <p>Error in mx.io.internal.arrayiter(as.array(data), as.array(label), unif.rnds,  : 
    basic_string::_M_replace_aux</p>
</blockquote>

<p>I follow the R regression example on mxnet website but I change the data into my own data which contains 109 examples and 1876 variables. The first several steps can run without error until ran the model building step. I just can't understand the error information mean. I wonder that it is because of my dataset or the way I deal with the data. </p>
