cython 编译 celely 运行失败 [AttributeError: 'method-wrapper' object has no attribute '__module__']

Question

我用python中的celery开发了一个项目，并使用cython编译pyd文件，每个文件都很好但是tasks.pyd，它无法运行。我认为该错误可能与@decarator有关，我尝试了没有解决方案的sererval methons，谁能帮助我？先谢谢了。

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

Answer 1

没有minimal reproducible example 就不可能知道，所以接下来是猜测。

我怀疑@app.task 要求函数具有一些 Cython 默认不提供的自省属性。尝试的事情：

1. 使用指令#cython: binding=True。这使得 Cython 函数成为一种自定义对象类型，其行为更像常规函数。
2. 使用 Cython 3 alpha（虽然谁知道你在这里使用的是什么版本的 Cython，因为你没有说）。它包含对函数自省的一些改进（并默认启用binding=True）。
3. 用 Python 编写这段代码（例如，您可以使用 exec）。
