In particular: The fork-emulation done in spawn mode will try to serialize some of the main module's state for transfer to the child process to initialize the child similarly; multiprocessing.Process itself is not picklable as of Python 3.7 (though there's a patch pending to fix it), so you definitely don't want to have it anywhere it might get pickled. So basically I want to pickle a figure object, compress it (size reduction+encryption) and then save it to disk. In particular: Find text between specific id beautifulsoup.
