``mx.symbol.batch_take``
================================================

Description
----------------------

Takes elements from a data batch.


.. note::   `batch_take` is deprecated. Use `pick` instead.

Given an input array of shape ``(d0, d1)`` and indices of shape ``(i0,)``, the result will be
an output array of shape ``(i0,)`` with::

	 output[i] = input[i, indices[i]]
	 

**Example**::

	 
	 x = [[ 1.,  2.],
	 [ 3.,  4.],
	 [ 5.,  6.]]
	 
	 // takes elements with specified indices
	 batch_take(x, [0,1,0]) = [ 1.  4.  5.]
	 
	 
Usage
----------

.. code:: r

	mx.symbol.batch_take(...)
