英文:
prevent AssertionError: daemonic processes are not allowed to have children
问题
I am running stuff using Pool/multiprocessing.
Whenever I call Pool again (nested) within one of the child processes of the main process, this error is raised?
prevent multiprocessing gives AssertionError: daemonic processes are not allowed to have children
Is there a way to detect if code is running already part of a Pool, to be able to prevent this error?

可以获取当前进程实例并检查它是否为守护进程：
from multiprocessing import process
print(f"当前进程是否为守护进程: {process.current_process().daemon}")
输出：
当前进程是否为守护进程: False
在进程池内，该 .daemon 属性将为 True。
英文:
Yes, you can get the current process instance and check whether it is daemonic or not:
from multiprocessing import process
print(f"is current process daemonic: {process.current_process().daemon}")
Output:
is current process daemonic: False
Inside a pool, that .daemon property will be True
