为什么会出现此错误？
TypeError: super(type, obj): obj must be an instance or subtype of type
这是我的models.py文件
class Lambda(Layer):
@interfaces.legacy_lambda_support
def __init__(self, function, output_shape=None,
mask=None, arguments=None, **kwargs):
super(Lambda, self).__init__(**kwargs)
self.function = function
self.arguments = arguments if arguments else {}
if mask is not None:
self.supports_masking = True
self.mask = mask
if output_shape is None:
self._output_shape = None
elif isinstance(output_shape, (tuple, list)):
self._output_shape = tuple(output_shape)
else:
if not callable(output_shape):
raise TypeError('In Lambda, `output_shape` '
'must be a list, a tuple, or a function.')
self._output_shape = output_shape
def call(self, inputs, mask=None):
arguments = self.arguments
if has_arg(self.function, 'mask'):
arguments['mask'] = mask
return self.function(inputs, **arguments)
完整的错误消息在这里，
647 def call(self, inputs, mask=None):
648 arguments = self.arguments
--> 649 if has_arg(self.function, 'mask'):
650 arguments['mask'] = mask
651 return self.function(inputs, **arguments)
TypeError: super(type, obj): obj must be an instance or subtype of type
有人可以向我解释错误的原因以及如何解决吗？如果需要，我愿意提供更多信息。
