How to use multi-threading to speed up Python imports?

I need to import two modules: A and B. Module A (which will be later used by B) takes too much time to load which slows down the whole code when it's ran sequentially.

Is there a way to import A concurrently while B is running in order to speed up the code? The idea being that A would be completely loaded by the time B gets to needing it without the latter having to wait for it.

Thanks.

For CPython, the GIL will prevent two threads from running concurrently so unless IO is being performed when your modules are imported then multiple threads will probably not help – Iain Shelvington Sep 14 '21 at 11:59
