@arita37 BdeuScore
has been changed to BDeuScore
in the latest version: https://github.com/pgmpy/pgmpy/blame/dev/CHANGELOG.md#L16
Sure, But, how to solve in
import bnlearn ?
Change manually the code ?

@arita37 I have updated the notebook to fix this. Thanks for reporting it.
Sorry, This is not notebook BUT pip install pgmy code

In that case, you can just change the import from Bdeu
to BDeu
in your code and it should work.
Think you need to re-publish the package to pip.
Thanks

@arita37 Are you still getting errors? It's working fine for me:
In [1]: from pgmpy.estimators import BDeuScore
In [2]: score = BDeuScore?
Init signature: BDeuScore(data, equivalent_sample_size=10, **kwargs)
Docstring: <no docstring>
Init docstring:
Class for Bayesian structure scoring for BayesianModels with Dirichlet priors.
The BDeu score is the result of setting all Dirichlet hyperparameters/pseudo_counts to
`equivalent_sample_size/variable_cardinality`.
The `score`-method measures how well a model is able to describe the given data set.
Parameters
----------
data: pandas DataFrame object
datafame object where each column represents one variable.
(If some values in the data are missing the data cells should be set to `numpy.NaN`.
Note that pandas converts each column containing `numpy.NaN`s to dtype `float`.)
equivalent_sample_size: int (default: 10)
The equivalent/imaginary sample size (of uniform pseudo samples) for the dirichlet hyperparameters.
The score is sensitive to this value, runs with different values might be useful.
state_names: dict (optional)
A dict indicating, for each variable, the discrete set of states (or values)
that the variable can take. If unspecified, the observed values in the data set
are taken to be the only possible states.
complete_samples_only: bool (optional, default `True`)
Specifies how to deal with missing data, if present. If set to `True` all rows
that contain `np.Nan` somewhere are ignored. If `False` then, for each variable,
every row where neither the variable nor its parents are `np.NaN` is used.
This sets the behavior of the `state_count`-method.
