python执行的Traceback输出不足

Question

如何进一步解决 Django 问题，即在回溯输出中仅列出内置包文件，而不是那些用户创建的文件，这并不能说明我创建的 *.py 文件中有什么问题。

Traceback (most recent call last):

关于如何进一步排除故障有什么想法吗？

Answer 1

您还没有添加代码。

此外，代码已经解释了那里发生的事情。您正在使用 wagtail 装饰器，您必须检查 decorator 方法的工作原理。

错误从最后一个开始

 File "/usr/local/lib/python3.7/site-packages/wagtail/utils/decorators.py", line 29, in __get__
    return self[owner]

我注意到您的问题与 threading 有关，我猜您正在处理大型数据集或文件。

在这里你可以提高费率

import sys, threading
sys.setrecursionlimit(10**7) # max depth of recursion
threading.stack_size(2**27)  # new thread will get stack of such size
