您好，我想知道如何在python中使用Enum

Question

I made an enum file and tried to import in the file showing next code (another file) But showing this error following :

File "C:/Users/1/PycharmProjects/assignment3/Program.py", line 61, in Program
    NN.TrainByBackProp(100000, 0.1, GradDescType.STOCHASTIC)
NameError: name 'GradDescType' is not defined

and this host file seems not recognize import when I imported like import Myenum which is belonged enum file. What should I correct to deal with this issue? Thank you for your response in advance. If you need more information, let me know I will respond as soon as possible.

enum file

import enum

class GradDescType(enum.Enum):

    BATCH=1
    STOCHASTIC=2
    MINIBATCH=2

class ActivationFunction(enum.Enum):

    SIGMOID=1
    SOFTMAX=2

another file

NN.TrainByBackProp(100000, 0.1, GradDescType.STOCHASTIC)

在“另一个文件”中，您需要导入已定义的两个枚举：

from <enum_file> import GradDescType, ActivationFunction
