mindspore.ops.functional
|
|
=============================
|
|
|
|
The functional operators are initialized Primitives and can be used directly as functions. An example of the use of the functional operator is as follows:
|
|
|
|
.. 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]
