mindspore.ops.functional
=============================
functional算子是经过初始化后的Primitive， ：
.. code-block :: python
from mindspore import Tensor, ops
from mindspore import dtype as mstype
input_x = Tensor(-1, mstype.int32)
input_dict = {'x':1, 'y':2}
result_abs = ops.absolute(input_x)
print(result_abs)
result_in_dict = ops.in_dict('x', input_dict)
print(result_in_dict)
result_not_in_dict = ops.not_in_dict('x', input_dict)
print(result_not_in_dict)
result_isconstant = ops.isconstant(input_x)
print(result_isconstant)
result_typeof = ops.typeof(input_x)
print(result_typeof)
# outputs:
# 1
# True
# False
# True
# Tensor[Int32]
