Yes, it surprised me as well, because VMs are supposed to be clones. All goes right in the VM, with the exception of q2 commands. Htop, ls, Firefox etc. I suspect then that it has to be something very specific of python vs the new Intel i9 CPUs (of course, beyond my knowledge). And I hope that it only happens within VMs. FYI, I found a thread with sombody complaning for the same error, using numpy in a VM Ubuntu 16.04 (but with Intel i3 CPU): Numpy crashes during tests with a "Illegal instruction (core dumped)". · Issue #9532 · numpy/numpy · GitHub
I will check if we can install Linux as OS and then report the result. Thanks!
