This worked for me:

git clone --branch python3_10 git@github.com:kapulkin/fn.py.git 
cd fn.py/
python setup.py install

Then

pip install cadCAD==0.4.28

succeeded.

Thanks @chuck-h that worked for me too. Seems like fn should be added to requirements for cadcad.

[LinuxIsCool]

In case anyone working with a requirements.txt file, having the following lie before cadcad works for me.

In requirements.txt:

...
https://github.com/kapulkin/fn.py/archive/refs/heads/python3_10.zip
...

Then:

pip3 install -r requirements.txt
