Error when trying to create PCA biplot with target label. Following this tutorial:
https://www.reneshbedre.com/blog/principal-component-analysis.html

pca_scores = PCA().fit_transform(X_st)
cluster.biplot(cscore=pca_scores, loadings=loadings, labels=X.columns.values, var1=round(pca_out.explained_variance_ratio_[0]*100, 2),
var2=round(pca_out.explained_variance_ratio_[1]*100, 2), colorlist=target)
