嗨
我有一些代码在我的CI失败（本地运行不会失败）。问题是类示例未通过isinstance()检查。

编码：

文件：main.py

class MyController(SuperController):
    # Overrides default definition of get_variables_context()
    from my_options import get_variables_context

文件：my_options.py

...
def get_variables_context(self: SuperController, **kwargs):
    from main import MyController
    self: MyController
    
    print(f"type(self) is {type(self)} (it {'IS' if (isinstance(self, MyController)) else 'IS NOT'} a subclass of MyController)")
    _super = super(MyController, self).get_variables_context(**kwargs) or dict()
    _super.update({ 'some_field': 'some value' })
    return _super

得到输出和错误：

type(self) is <class '__main__.MyController'> (it IS NOT a subclass of MyController)
Traceback (most recent call last):
  File "main.py", line 24, in <module>
    MyController.main(**params)
  File "/tmp/example/flow.py", line 391, in main
    _tests_suite, _, _ = self.prepare()
  File "/tmp/example/flow.py", line 359, in prepare
    context['variables_context'] = self.get_variables_context(**context)
  File "/tmp/example/my_options.py", line 81, in get_variables_context
    _super = super(SomeController, self).get_variables_context(**kwargs) or dict()
TypeError: super(type, obj): obj must be an instance or subtype of type
