Returns a symbolic sequence of booleans with the same length as ``seq``. The
first element of the sequence is 1 and all others are 0.
Example:
>>> x = C.input_variable(shape=(3,2))
>>> y = C.sequence.is_first(x)
>>> x0 = np.reshape(np.arange(24.0,dtype=np.float32),(4,3,2))
>>> y.eval({x:x0})
array([[ 1., 0., 0., 0.]], dtype=float32)
Args:
seq: the symbolic tensor denoting a sequence
name (str): the name of the node in the network
Returns:
