Hello,
Yeah sure I’m checking with them as well. Meanwhile, this is a purely python related error following what you suggested to me about installing the wheel package:
I tried installing the wheel package using
(venv) Bernards-MacBook-Pro:Python Bernard$ pip install /Users/Bernard/Downloads/CoolProp-6.4.1-cp38-cp38-macosx_10_9_x86_64.whl
but it gave me this error
ERROR: CoolProp-6.4.1-cp38-cp38-macosx_10_9_x86_64.whl is not a supported wheel on this platform.
I assume this means that i need python 3.8 for this wheel to work, which I have. I typed python3 in terminal it gave me 3.8.10, i typed python3 in PyCharm and it gave me 3.9.5, how come? So i searched for python 3.9 in my MacBook and i couldn’t find any traces of it, except for in a project folder: /Users/Bernard/PycharmProjects/Isentropic SUS Model/venv/lib/python3.9
However, 3.8 exists in the Applications folder. Any idea how to remove all traces of 3.9?
Thanks and regards,
Bernard Marjaba
