   Hi @mdespriee 
   Nice try with Scala package! In your case, you can implement in the following ways:
   ```Scala
   Symbol.random_normal(i.output)()(Map("loc" -> mean, ...))
   ```
   Just put all of your args in the map. You can always check [Python API example](http://mxnet.apache.org/api/python/symbol/symbol.html#mxnet.symbol.random_normal). 
   
   BTW, in the future, you can call `Symbol.api.random_normal`. This is a brand new api set introduced in v1.3 (not coming yet..) here is an example:
   ```Scala
     /**
     * <pre>
     * Draw random samples from a normal (Gaussian) distribution.
     * 
     * .. note:: The existing alias ``normal`` is deprecated.
     * 
     * Samples are distributed according to a normal distribution parametrized by *loc* (mean) and *scale* (standard deviation).
     * 
     * Example::
     * 
     *    normal(loc=0, scale=1, shape=(2,2)) = [[ 1.89171135, -1.16881478],
     *                                           [-1.23474145,  1.55807114]]
     * 
     * 
     * Defined in src/operator/random/sample_op.cc:L85
     * </pre>
     * @param loc		Mean of the distribution.
     * @param scale		Standard deviation of the distribution.
     * @param shape		Shape of the output.
     * @param ctx		Context of output, in format [cpu|gpu|cpu_pinned](n). Only used for imperative calls.
     * @param dtype		DType of the output in case this can't be inferred. Defaults to float32 if not defined (dtype=None).
     * @return org.apache.mxnet.Symbol
     */
   @Experimental
   def random_normal (loc : Option[org.apache.mxnet.Base.MXFloat] = None, scale : Option[org.apache.mxnet.Base.MXFloat] = None, shape : Option[org.apache.mxnet.Shape] = None, ctx : Option[String] = None, dtype : Option[String] = None, name : String = null, attr : Map[String, String] = null) : org.apache.mxnet.Symbol
   ```
   @mxnet-label-bot can you label this as [scala] ?
