Description

np array version - to get an idea

==============

test1 = np.array([]) 

test1 = np.concatenate((test1, test2)) # test2 may any value

This is working... 

 

====================

mx.nd.array version - bug is here

=====================

test1 = mx.nd.array([], ctx=ctx)

mx.ndarray.concat(test1, test2, dim=0) # this return and assertion error (len > 1 on test1)

1. concatenating to an empty array is importatnt feature 

Note that same thing is working with np array
