Когда я запускаю команду fab, я получил ошибку ниже, я не могу выполнить ни одну задачу fab, даже если это простая задача печати. Ошибка при разборе-задача:

Фрагменты моего фабфайла. Я подозреваю, что это связано с классом инициализации.

Ниже приведен внутренний класс для загрузки данных из файлов. как часть инициализации. Нет многопоточности.

 class All_Slave_Data(object):  
    all_loaded_slave_data = {}

    def __init__(self, directory='.'):
        # Make this the default logger
        log = _globallog

        self.initialized = False
        # Load from multiple files.
        fileCount = 0

        # Do not descend into subdirectories
        filenames = [f for f in glob.glob(os.path.join(_basepath, 'slaves_*.yaml'))]
        for filename in filenames:
            <some file operations>
            self.all_loaded_slave_data.update(partial_data)


    def getData(self):
        if not self.all_loaded_slave_data:
            self.__init__()
        return self.all_loaded_slave_data


_allSlaveData = All_Slave_Data()
_the_slave_data = _allSlaveData.getData()



 

ниже приведена простая задача, я пробовал, на самом деле я не могу выполнить ни одной задачи.

 @task  
def export_master_data(c, directory='.', log=_globallog):
   <some simple actions, from the error log, it did not touch the task body>
 

Я мог бы успешно выполнить ту же команду fab в python3.8.2.

Если у вас есть какие-либо подсказки или решения, мы будем очень признательны!

Утверждено, что это проблема с Python3.6.Проблема не существует в Python3. 7 и Python3.8.
