gnikh opened a new issue #8595: how to implement function like numpy.random.choice using ndarray?
URL: https://github.com/apache/incubator-mxnet/issues/8595
 
 
   I want to sample from some discrete elements, each of which with a given probability, like the function of numpy:
   numpy.random.choice(a, size=None, replace=True, **p=None**)
   https://docs.scipy.org/doc/numpy-1.13.0/reference/generated/numpy.random.choice.html
   
   The sampling is one step of training on gpu, so I want to implement it using ndarray to avoid data copy between cpu and gpu.
   
    #Thanks.
