Python Fire 模块不在 `-h` 中显示 COMMANDS

Question

I am using the python Fire module with an abstract parent class and a child class. Not all functions are abstract, some functions do not need to be replicated for each child:

parent class

from abc import ABC, abstractmethod

class Foo(ABC):
    @abstractmethod
    def __init__(self, val=None):
        # some initialisations

    @abstractmethod
    def fun1(self, file=None):
       # Some calls

    def fun2(self):
       # Non abastract func... Some calls

child class (test.py)

import fire
from foo import Foo

class Child(Foo)
     def __init__(self, val=None):
        super().__init__(val)
        # some initialisations

     def fun1(file='path/to/file')
        # do some stuff

if __name__ == '__main__':
    fire.Fire(Child)

when I run python CLI with python -m test --help I do not get any COMMANDS ie Fire is not recognising any functions to run. However it is recognising the parent global variables and init flags to set so why is this happening?

Answer 1

try passing it the instantiated object instead like they do here

fire.Fire(Child())
