Hard "No module named 'decorators'" Problem..

[Physalis87]

Dear Ankur Ankan,

could you be so kind and have a look at the error thrown by running python manage.py runserver ?
It is hard for me to trace back to any source, already spent many hours adopting files and versions of packages back and fourth.

Thank you and best
Daniel

Hi @Physalis87 , this project hasn't been maintained (and doesn't have many useful features) in a while so I am not sure if there is an easy way to get it back working easily. I am not sure what your usecase is ?, but if you are looking for a graphical way to work with DAGs/bayesian networks, you can also look into http://dagitty.net/

[Physalis87]

Hi @ankurankan, thanks a lot for your quick reply and your suggestion. I checked dagitty.net, but as far as I see now it may not meet my requirements. I would like to

• Export the visual graph from graphical editor as a pgmpy (networkx!?) compatible format to use in my code
• Even more so run the pgmpy-Code (and my own implemented Algorithms) interactively with the graphical user interface (I think dagitty does this for d-seperation and other, but I am not sure if I can integrate my stuff there?)

Best, Daniel

[ankurankan]

@Physalis87 Yes, you are right. dagitty mainly focuses on the causal interpretation of Bayesian networks. I don't think there is any simple way for your use case right now. This current repo is quite outdated, and you will need to add quite a few features yourself to have everything that you need. If you don't care much about the graphical interface, then you can use the pgmpy package directly.
