Web6 dec. 2024 · As the current implementation of multiprocessing has been extensively refactored to be based on contexts, we need to provide a NoDaemonContext class that has our NoDaemonProcess as attribute. MyPool will then use that context instead of the default one. That said, I should warn that there are at least 2 caveats to this approach: WebIn this lesson, you’ll dive deeper into how you can use multiprocessing.Pool. It creates multiple Python processes in the background and spreads out your computations for you … how to set up snowsql
