Segmentation fault: 11 - SMAC - MacOS catalina

[tsiakmaki]

Hi all and thank you for your contribution.

I am trying to use SMAC optimizer in my tests on a Mac with Catalina os.
I have

• installed swig
• run the: CFLAGS=-stdlib=libc++ pip install smac
• run the: pip install lale[full]
  in my virtual python environment, but running my code with SMAC optimizer with my custom operator, and I am getting:
  Segmentation fault: 11
  Any ideas what i have done wrong?

(when using Hyperopt, I am getting results)

Thank you in advance for you time.

Thank you for your feedback! Quoting from the Auto-Sklearn installation instructions:

We currently do not know if auto-sklearn works on OSX.

Also, some SMAC users have reported difficulties with segmentation faults in this issue. That means this might be a problem in the underlying library and it is unclear whether there is anything we can do at the Lale level that would alleviate it.

I was unable to fix it. Anyway, thank you for your time.
