"Fatal error: 'omp.h' file not found" when importing plugins

[ElisabethGriesbauer]

Hi!
I am on macOS 14.0 using python 3.9.18 and conda 23.5.2. I created a conda env and cloned synthcity and then in python tried:

import synthcity.plugins

But I get the following error message:

Intel MKL WARNING: Support of Intel(R) Streaming SIMD Extensions 4.2 (Intel(R) SSE4.2) enabled only processors has been deprecated. Intel oneAPI Math Kernel Library 2025.0 will require Intel(R) Advanced Vector Extensions (Intel(R) AVX) instructions.
<stdin>:1:10: fatal error: 'omp.h' file not found
#include <omp.h>
         ^~~~~~~
1 error generated.
[KeOps] Warning : omp.h header is not in the path, disabling OpenMP.
[KeOps] Warning : Cuda libraries were not detected on the system ; using cpu only mode

Same thing happens when I install synthcity with pip. How can I solve this?
