In this Python multiprocessing example, we will merge all our knowledge together. Suppose we have some tasks to accomplish. To get that task done, we will use several processes. So, we will maintain two queue. One will contain the tasks and the other will contain the log of completed task...
Can anyone help provide an example of how to use Faiss with python multiprocessing? Currently I can only load faiss index in each individual process, and in each process the index is loaded into its own memory (leading to large memory consumption). Any build-in way I can load the index ...

In general, start-methods can be modified with multiprocessing.set_start_method(method). Since Python 3.8, macOS also uses 'spawn' instead of 'fork' as default. It's general a good practice to separate any script in upper "definition" and lower "execution as main", to make code ...
