mdespriee opened a new issue #12140: Impossible to provide arguments to 
random_normal in scala ?
URL: https://github.com/apache/incubator-mxnet/issues/12140
 
 
   
   ## Description
   I'm trying to use random_normal in the Symbol API. In scala.
   The docs mentions that loc and scale could be Symbols and have a shape 
(that's what I'm looking for). Although, when I try to use the symbol:
   ```
   val mean:Symbol...
   val std:Symbol...
   Symbol.random_normal(i.output)(mean, std)()
   ``` 
   MXNet complains that arguments are incorrect.
   ```
   org.apache.mxnet.MXNetError: [23:24:15] src/core/symbolic.cc:290: Check 
failed: args.size() <= n_req (2 vs. 0) Incorrect number of arguments, requires 
0, provided 2
   ```
   Sounds like a bug to me. Or do I miss something ?
   
   ## Environment 
   - Linux setup using  
https://raw.githubusercontent.com/apache/incubator-mxnet/1.2.1/ci/docker/install/ubuntu_core.sh
 (actually in a Docker)
   - MXNet 1.2.1, scala 2.11.11
   
   ## Full code
   ```
   object NormalTest extends App {
     val means = Symbol.Variable("mean")
     val std = Symbol.Variable("std")
     val s = Symbol.random_normal("gaussian")(means, std)()
   
     val exec = s.bind(Context.defaultCtx, Map(
       "means" -> NDArray.array(Array(0f, 10f), Shape(2)),
       "std" -> NDArray.array(Array(1f, 2f), Shape(2))
     ))
   
     exec.forward()
     println(s"Result= ${exec.outputs.head.toArray.mkString(",")} ")
   }
   ```
