Error with python package pgmpy #

[myrasika]

I'm running into error using pgmpy doing calculations for conditional probability (bayesian network)

This is the structure of the network.
weather_chart = BayesianModel([('Weather', 'Temperature'),
('Weather', 'Wind'),
('Weather', 'Rain'),
('Temperature', 'Bring_Jacket'),
('Wind', 'Bring_Jacket'),
('Rain', 'Bring_Jacket'),
('Temperature', 'Bring_Umbrella'),
('Wind', 'Bring_Umbrella'),
('Rain', 'Bring_Umbrella')])

The error I get is when running : model.check_model()

The error I get:
ValueError Traceback (most recent call last)
in
1 # Check model for correctness
----> 2 weather_chart.check_model()

~/Library/Python/3.9/lib/python/site-packages/pgmpy/models/BayesianNetwork.py in check_model(self)
427 # Check if the values of the CPD sum to 1.
428 if not cpd.is_valid_cpd():
--> 429 raise ValueError(
430 f"Sum or integral of conditional probabilities for node {node} is not equal to 1."
431 )

ValueError: Sum or integral of conditional probabilities for node Temperature is not equal to 1.
