Installation of pycddlib dependency on MacOS

[stephane-caron]

From your log, the main error is that pip fails to build pycddlib which is a key dependency for pypoman. Let's continue the investigation in mcmtroffaes/pycddlib#49

Dear @stephane-caron, I tried to install pypoman on a MacOS 11.6 with Python 3.8.
I didn't get any problem during the installation but when I try to run your example program I get the following message:
File "/Users/user1/.conda/envs/ExtremePoints/lib/python3.8/site-packages/pypoman/duality.py", line 120, in compute_polytope_vertices
mat = cdd.Matrix(hstack([b, -A]), number_type='float')
AttributeError: module 'cdd' has no attribute 'Matrix'

What am I doing wrong? I thank you in advance for your help.

@davidaino this seems like a different problem than the original question from @alphaville. Can you open a separate issue for it?

In your issue description, please include the output of:

import cdd
print(cdd.__version__)
