Hi, I have encountered the same problem, you should refer to pdp’s documentation.

def plot_pdp(feat_name, clusters=None):
#feat_name = feat_name or feat
    p = pdp.pdp_isolate(m, x, feature=feat_name, model_features=x.columns)
    return pdp.pdp_plot(p, feat_name, plot_lines=True,
                   cluster=clusters is not None, n_cluster_centers=clusters)

And then

plot_pdp(feat_name='YearMade')

Hi, my code above doesn’t work?

It worked fine for me! you need to specify another argument model_features.

I understand I maybe talking about this late, but I went instead with below code:

def plot_pdp(feat, clusters = None, feat_name = None):
    feat_name = feat_name or feat
    p = pdp.pdp_isolate(m, x, feature = feat, model_features = x.columns)
    return pdp.pdp_plot(p, feat_name, plot_lines = True,
                        cluster = clusters is not None,
                        n_cluster_centers = clusters)
