Issue with shapes of values of TabularCPD

[FiorenzoParascandolo1]

`cpd_covid = TabularCPD(variable='Covid',
variable_card=2,
values=[[0.01, 0.15],
[0.99, 0.85]],
evidence=["Follow_rule"],
evidence_card=[2],
state_names={'Covid': ['Positive', 'Negative'],
'Follow_rule': ['Yes', 'No']})

cpd_influence = TabularCPD(variable='Influence',
variable_card=2,
values=[[0.01, 0.09],
[0.99, 0.91]],
evidence=["Follow_rule"],
evidence_card=[2],
state_names={'Influence': ['Positive', 'Negative'],
'Follow_rule': ['Yes', 'No']})

cpd_pneumonia = TabularCPD(variable='Pneumonia',
variable_card=2,
values=[[0,27, 0,26, 0.01, 0.01],
[0.73, 0.74, 0.99, 0.99]],
evidence=['Covid', 'Influence'],
evidence_card=[2, 2])`

evidence_card=[2, 2]) raise TypeError("Values must be a 2D list/array") TypeError: Values must be a 2D list/array

I've a problem with the shapes of evidence. Is there a tutorial which explain its? The notebook "pgmpy_notebook" doesn't work with the representation of arrays of "values"

@FiorenzoParascandolo1 There seems to be a typo in your values argument. Instead of 0.27, it is 0,27. Same for 0.26.
