I am trying to pdp_isolate the ‘Sex’ feature in the Titanic competition, but I get an error if I try running the same code as shown in the lesson. Contrary to the original lesson’s code, pdp_isolate requires a new argument in addition to feat: features (the features of the model). So I did:
features = [feat for feat in df_raw.columns]
['PassengerId', 'Survived', 'Pclass', 'Name', 'Sex', 'Age', 'SibSp', 'Parch', 'Ticket', 'Fare', 'Cabin', 'Embarked']
def plot_pdp(feat, clusters=None, feat_name=None): feat_name = feat_name or feat p = pdp.pdp_isolate(m, df_raw, features, feat) return plot_pdp(p, feat_name, plot_lines=True, cluster=clusters is not None, n_cluster_centers=clusters) plot_pdp('Sex')
But I get this error:
TypeError: can't multiply sequence by non-int of type 'float'
Did anyone have any trouble using this function? What does this TypeError mean?
