What are some common mistakes when using multiprocessing in Python?
Some common mistakes include not using the if __name__ == '__main__':
guard, which can lead to issues on Windows.
Why is the if __name__ == '__main__':
guard important?
It's crucial because it prevents the child processes from executing the main module code again, which can cause recursion.
Are there any performance issues I should be aware of?
Yes, using too many processes can lead to overhead and context switching, which may degrade performance.
How can I effectively manage the number of processes?
You can use the multiprocessing.Pool
class to manage a pool of worker processes and control the number of concurrent tasks.
