In Python 3.8 the default start method has changed from fork to spawn on macOS. https://docs.python.org/3/whatsnew/3.8.html#multiprocessing get_all_start_methods() says: "Returns a list of the supported start methods, the first of which is the default." https://docs.python.org/3/library/multiprocessing.html?highlight=finalize#multiprocessing.get_all_start_methods However, it appears to still return fork as default: Python 3.8.1 (default, Dec 22 2019, 03:45:23) [Clang 10.0.1 (clang-1001.0.46.4)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import multiprocessing >>> multiprocessing.get_all_start_methods() ['fork', 'spawn', 'forkserver'] >>> Thank you! |

Good catch, Stefen! This seems like we forgot to update multiprocessing.get_all_start_methods() when making the change to make "spawn" the default on macOS. I suggest updating it accordingly. |
