bayesian networks and data science

Question

I'm trying to build a bayesian.network using Pyagrum in python, now when it comes to importing data, I have a csv file, i tried to use it as a database for my BN, however this message keeps showing:

MissingVariableInDatabase: [pyAgrum] Missing variable name in database: Variable 'Mois' is missing

'Mois' is the title of thefirst varaible in my database.

Answer 1

it looks like in your BN, there is a variable "Mois" but not in your csv. Does it make sense?

Answer 2

(I tried to add this as a comments to the last answer but formatting is not easy in comment so I add it as a new answer)

You could try to create your learner without the bn

learner = gum.BNLearner('Donnees.csv')

and look at the foudn variables in the csv:

print(learner.names())
