Invalid CPU Type

[GregoryGelfond]

I'm currently attempting to use problog on macOS Tahoe (26.2), installed via pip 25.3 with python 3.13, and am running into an issue when attempting to query the tutorial program:

% Probabilistic facts:
0.5::heads1.
0.6::heads2.

% Rules:
someHeads :- heads1.
someHeads :- heads2.

% Queries:
query(someHeads).

Here is the crash log I get when executing problog test.problog:

Traceback (most recent call last):

An unexpected error has occurred.

Any help getting this working would be appreciated.

It seems to me that this is an issue with the bundled dsharp compiler, as it is not compiled for ARM processors. An alternative is to use the PySDD backend, which should be used automatically when available. Install with pip install pysdd
