I’ve trained my model using mxnet_1.3 python HybridBlock. Then I load the 
trained model in Scala. I didn’t get any errors when I run 
[demo.Scala,](https://github.com/ustcfd/mxnet_scala/blob/master/scala_model_load/demo.scala)
 and the output is shown in the following.

But now I got few problems:
-  Is possible to get the true value of the NDarray? 
I followed the examples of the API 
[https://mxnet.apache.org/api/scala/ndarray.html](url) trying to print the 
value of NDarray by toarray. But I got an odd output looks like “F@4b553d2d” 
including the final output. I am very confused about the output value of 
NDArray.The demo code is shown in demo.Scala.

- The API document of Mxnet demonstrates that the type input of the 
NDArray.array is restricted to Array[float]. 
Do I have to flatten my n-dimension matrix to one-dimension Array[float] when I 
want to create my own data?
Are there any other strategies to feed my data just like Numpy or python which 
directly take a matrix as an input?
 
Maybe I was doing something wrong. Please suggest!
Thank you
