cython 编译的 celely run 失败 [属性错误：'method-wrapper'对象没有属性"__module__"]

Question

我用python中的celener开发了一个项目，并使用cython编译pyd文件，每个文件都很好，但tasks.pyd无法运行。我想这个bug可能与@decator有关，我尝试了一些没有解决方案的方法，谁能帮我？首先谢谢。

这是我在tasks.py 中的代码

from celery.utils.log import get_task_logger
logger = get_task_logger(__name__)
@app.task
def myTaskFunc(arg1=None, arg2=None):
some code

如果没有一个最小的可复制示例，就不可能知道，所以下面是一个猜测。

我怀疑@app.task要求函数具有Cython默认情况下不提供的某些内省属性。尝试的东西：

1. 使用指令#cython: binding=True。这使得Cython函数成为一种行为更像常规函数的自定义对象类型
2. 使用Cython 3 alpha(尽管谁知道你在这里使用的是什么版本的Cython，因为你没有说(。它包含一些对功能内省的改进(默认情况下启用binding=True(
3. 用Python编写这段代码(例如，可以使用exec(
