Getting a Process.start() error pickle.PicklingError: Can't pickle : it's not found as __builtin__.module with Python 2.7

[marc nicole via Python-list]

Hello,

I am using Python 2.7 on Windows 10 and I want to launch a process
independently of the rest of the code so that the execution continues while
the started process proceeds. I am using Process().start() from Python 2.7
as follows:

from multiprocessing import Process
def do_something(text):
print(text)
if __name__ == "__main__":
q = Process(target=do_something,args=("somecmd") )
q.start()
# following code should execute right after the q.start() call (not
until it returns)
.


But getting the error at the call of Process().start():
pickle.PicklingError: Can't pickle : it's not found as
__builtin__.module

anybody could provide an alternative to call the function do_something() in
a separate thread ?

Why? Install Python 3.12 and it will be easier to get help and support.
If you have legacy that still needs porting then you can install 3.12 along side
the unsupported 3.12.
