When trying to run dask distributed on ARM you will end with a segmentation fault on multiple in multiple tests; Works on AMD64 but does not work on ARM or AARCH64 and results in a Signal 11. Example; # python Python 3.6.6 (default, Sep 29 2018, 05:50:41) [GCC 4.2.1 Compatible FreeBSD Clang 6.0.1 (tags/RELEASE_601/final 335540)] on freebsd12 Type "help", "copyright", "credits" or "license" for more information. >>> from dask.distributed import Client >>> client = Client() Segmentation fault (core dumped) # gdb /usr/local/bin/python3.6 python3.6.core GNU gdb (GDB) 8.1 [GDB v8.1 for FreeBSD] Copyright (C) 2018 Free Software Foundation, Inc.
