我怀疑这对我来说是一种 klugefest，但我正在使用 Luigi 和 Sciluigi 模块，它们在初始化返回“自我”之前设置了许多关键参数。如果我在返回 self 后尝试对这些参数进行粗暴处理，Luigi.Parameter 对象会以这样的方式掩盖它们，以至于我无法做我需要做的事情。
luigi 和 sciluigi 类（使用它们时）包含 no __init__。如果我尝试插入__init__或调用super(ChildClass, self).__init__(*args, **kwargs)...我会收到奇怪的错误“意外参数”错误。
所以 Sciluigi 类看起来像这样......
class MyTask(sciluigi.task):
param1 = sciluigi.Parameter(default='Yes') #String only
param2 = sciluigi.Parameter(default='No') #String only
def out_target(self):
return sciluigi.TargetInfo(self, self.out)
def run(self):
with self.out_target().open('w') as foofile:
foofile.write('foo\n')
所以...我希望我可以通过 setattr PRIOR 动态设置一些参数，以实际返回“自我”。但是 setattr 需要对象。
我希望我能做类似的事情......
setattr(inspect.stack()[?][?], 'DynamicVar', sciluigi.Parameter(default='Yes') )

好吧，我不确定哪些信息最有帮助。
第一个问题是；我无法添加初始化。实际代码如下，__init__添加了一个方法。如果我尝试运行它，我已经包含了结果错误。它同样的错误是如果我运行超级调用__init__
class FileConverter(sciluigi.Task):
"""
"""
in_target = None # Mandatory
out = sciluigi.Parameter() # <file>
exepath = sciluigi.Parameter(default = "")
def __init__(self):
self.var = 'anything'
def out_target(self):
log.debug("In 'FileConverter.out_target'... ")
return sciluigi.TargetInfo(self, self.out)
def run(self):
result = None
command = ''.join([
self.exepath, _slash, "FileConverter ",
" -in ", self.in_target().path,
" -out ", self.out_target().path,
" -out_type ", self.file_type
])
log.info("RUNNING COMMAND: " + command)
result = self.ex(command)
log.info("result: " + result[1])
错误

第二个问题是：
如果我等待 self 返回，我将无法再区分（例如使用上面的代码）......
in_target = None # Mandatory
out = sciluigi.Parameter() # <file>
如果我执行type(out), type 报告参数只是一个字符串（不是 sciluigi.Parameter 对象），所以如果我尝试使用 `ìsinstance(out, sciluigi.Parameter)...它返回 False。
底线是：
我需要能够动态（以编程方式）设置 sciluigi.Parameter 对象，随后能够区分 sciluigi.Parameter() 对象变量（如out）和“真实” str() 对象（如in_target）
我希望这是有道理的。
