AttributeError: 'CID' object has no attribute 'is_dconnected' in Why_fairness_labels notebook

Describe the Issue A clear and concise description of what the Issue is.

Your environment

• PyCID version/commit hash : 114e1fdcd4
• Python version : 3.9.7
• Operating System : Ubuntu

Steps to reproduce In the Why_fair_labels_may_yield_unfair_models_AAAI_22 notebook, in cell [4], I get the error:

AttributeError: 'CID' object has no attribute 'is_dconnected'

Pgmpy renamed a method name (that we inherit) from "is_active_trail" to "is_dconnected", and we've updated accordingly. Try upgrading your pgmpy to 0.1.17 to fix the problem.

Thank you. This was indeed an environment issue. It's fixed on my end.

For what it's worth, I'm getting different results in two different environments still:

• In the development environment set up with python3 -m pip install --editable .[test] from a clone of master, it works. pgmpy is version 0.1.17

• In a general Python 3 environment, pycid is installed by the notebook with the following code block:

#importing necessary libraries
try:
    import pycid
except ModuleNotFoundError:
    import sys
    !{sys.executable} -m pip install git+https://github.com/causalincentives/pycid
    import pycid

For some reason, in this environment pgmpy is installed as version 0.1.13.

Good! Re the general Python3 environment, I think git calls setup.py, which calls setup.cfg, which does currently include the code install_requires=pgmpy==0.1.17. Not sure why it's not working. @Jamesfox1 , any ideas?

Thanks for identifying this @sbenthall ! I think I've now fixed this problem with the latest PyCID release.

Namely, running the following does now install pgmpy as version 0.1.17:

try:
    import pycid
except ModuleNotFoundError:
    import sys
    !{sys.executable} -m pip install git+https://github.com/causalincentives/pycid
    import pycid
