I have installed haddock2.4-2020-06 on a Mac (version 10.12.6), following the instructions from here: https://www.bonvinlab.org/education/HADDOCK-local-tutorial/
The computer uses Python 3:
bash-3.2$ which python
The Python scripts are all written in Python 2. I adapted them accordingly.
However, I am running into a more difficult issue when the script haddock/Haddock/ThirdParty/DictWithDefault.py
tries to import UserDict (line 3).
After some research, I found out that the module UserDict has been removed and cannot be found in Python 3.
